Abstract:

We present a hybrid microwave superconducting quantum interference device (SQUID) multiplexer that combines two frequency-division multiplexing techniques to allow multiplexing a given number of cryogenic detectors with only a fraction of frequency encoding resonators. Similar to conventional microwave SQUID multiplexing, our multiplexer relies on inductively coupling non-hysteretic, unshunted rf-SQUIDs to superconducting microwave resonators as well as applying flux ramp modulation for output signal linearization. However, instead of utilizing one resonator per SQUID, we couple multiple SQUIDs to a common readout resonator and encode the SQUID input signals in sidebands of the microwave carrier by varying the flux ramp modulation frequency for each SQUID. We prove the suitability of our approach using a prototype device and argue by means of fundamental information theory that our approach is particularly suited for reading out large cryogenic bolometer arrays.

Abstract:

Squid (Loligo sp) is a potential fishery commodity in Indonesia.Squid consumption in Indonesia is dominated by fresh squid product. There are not many diversified squid products. The flouring process is one form of diversification of squid product.Squid flour can be used as processed food such as cakes or as an additional flavoring to food. The quality of flour is determined by the proximate content of the flour. This research aims to determine the nutritional content through proximate analysis of squid flour. Squid flour is processed from the head, body, and ink of squid. The squids body parts are cleaned, weighed, and then dried in an oven. The next procedures is proximate analysis. The results showed that the highest protein content was found in squid body flour (68.98%), and the lowest was in squid ink flour (50.87%). The highest fat content was found in squid head flour (4.91%) and the lowest in squid ink flour (2.59%). The highest water content was found in squid ink flour, 15.32 (%) and the lowest in squid body flour (3.22%).

MORPHOLOGY, CLASIFICATION, AND DISTRIBUTION OF SQUID FAMILY LOLINGINIDAE. Squids are one of Indonesian export commodities that is produced in frozen, salted, dried or canned, however the information about biology, ecology, habitat and distribution of squid are little known. Squid have ten tentacles equipped with suction, and generates ink to defend against their enemies. Squids are demersal or semi-pelagic animal that lives in the waters column up to a depth of 400 m with diurnal movements. Squids reproduce sexually and by deocious. Squids with family Lolinginidae (genus Lolious) are distributed across the Indonesian waters with temperatures of 8 to 32 C and salinity of 8.5 to 30 ppm. Familly Lolinginidae is grouped into several genera included Afrololigo, Allotheuthis, Dorytheuthis, Heterololigo, Loliolus, Lollinguncula, Pickfordiateuthis, Sepioteuthis, dan Urotheuthis

Abstract:

The data presented provides new information on the distribution of Antarctic squids and on the summer diet of the emperor penguins. The diet of 58 adult emperor penguins (Aptenodytes forsteri) on the fast ice of the Drescher Inlet, Vestkapp Ice Shelf (72°52′S, 19°25′W) in the eastern Weddell Sea was investigated. Prey consisted principally of squid, fish, krill, amphipods and isopods. Squids were identified by the lower beaks and allometric equations were used to estimate the squid biomass represented. Beaks occurred in 93% of the stomach samples. Each sample contained a mean of 27 beaks (range 1–206). Ninety-two percent of the squids could be identified by the lower beaks and belonged to four families (Onychoteuthidae, Psychroteuthidae, Neoteuthidae and Gonatidae). The most abundant squid was Psychroteuthis glacialis which occurred in 52 samples with lower rostral lengths (LRL) ranging from 1.4–7.2 mm. Forty-five samples contained Alluroteuthis antarcticus (LRL range 1.8–5.8 mm), 17 Kondakovia longimana (LRL range 4–12.1 mm), and four Gonatus antarcticus (LRL range 4.1–6.1 mm). In terms of biomass K. longimana was the most important species taken by the penguins comprising 50% of total estimated squid wet mass (245348 g) in 1990 and 48% in 1992 (154873 g). However, if only fresh beaks were considered for estimations of squid consumption, i.e. beaks that have been accumulated for not longer than 5–6 days in the stomachs, squid diet was of minor importance. Then total squid wet mass accounted for only 4809 g in 1990 and 5445 g in 1992 which implies that one penguin took c.30 g squid d−1 with P. glacialis and A. antarcticus being the most important by mass. The prey composition suggests that emperor penguins take squid at the steep slope regions of the eastern Weddell Sea.

Abstract:

The dc SQUID had been presented for use in the rf SQUID instead of a weak link. The new device, referred to as “double SQUID”, possesses a large output signal (hundreds of microvolts) in operating in a hysteretic mode. For making an operating mode a double SQUID is coupled to a circuit traditional for rf SQUIDs containing a tank circuit and an rf current pumping generator. The magnetic flux being measured is recognized by the dc SQUID quantization loop which results in changing its critical current. As a result the height of the flat part of the tank circuit I–V characteristics coupled to a double SQUID is modulated. It is this modulation that is the SQUID output signal. The experimental investigations of the double SQUID showed the validity of the assumptions under consideration. Output signals up to 690 μV, noise spectral density ≈2×10−5ϕ0/ Hz 1/2 (ϕ0 is the flux quantum) and energy resolution ≈1.4×10−29 J/Hz have been obtained.

Abstract:

Giant squids ( Architeuthis ) are a legendary species among the cephalopods. They live in the deep sea and are well known for their enormous body and giant eyes. It has been suggested that their giant eyes are not adapted for the detection of either mates or prey at distance, but rather are best suited for monitoring very large predators, such as sperm whales, at distances exceeding 120 m and at a depth below 600 m (Nilsson et al. 2012 Curr. Biol. 22 , 683–688. ( doi:10.1016/j.cub.2012.02.031 )). However, it is not clear how the brain of giant squids processes visual information. In this study, the optic lobe of a giant squid ( Architeuthis dux , male, mantle length 89 cm), which was caught by local fishermen off the northeastern coast of Taiwan, was scanned using high-resolution magnetic resonance imaging in order to examine its internal structure. It was evident that the volume ratio of the optic lobe to the eye in the giant squid is much smaller than that in the oval squid ( Sepioteuthis lessoniana ) and the cuttlefish ( Sepia pharaonis ). Furthermore, the cell density in the cortex of the optic lobe is significantly higher in the giant squid than in oval squids and cuttlefish, with the relative thickness of the cortex being much larger in Architeuthis optic lobe than in cuttlefish. This indicates that the relative size of the medulla of the optic lobe in the giant squid is disproportionally smaller compared with these two cephalopod species. This morphological study of the giant squid brain, though limited only to the optic lobe, provides the first evidence to support that the optic lobe cortex, the visual information processing area in cephalopods, is well developed in the giant squid. In comparison, the optic lobe medulla, the visuomotor integration centre in cephalopods, is much less developed in the giant squid than other species. This finding suggests that, despite the giant eye and a full-fledged cortex within the optic lobe, the brain of giant squids has not evolved proportionally in terms of performing complex tasks compared with shallow-water cephalopod species.

Abstract:

Squids, when spawning, attach their eggs to the preferred substrate to develop well in the selected conditions. Experimental fishing research was conducted by direct observation of squid activities in the spawning area where squid eggs were attached to different substrates. The adult squid would first conduct an inspection and then attach their eggs to the selected substrate. The results showed that squid egg attachment time was conducted in the morning from 06.00 AM to 07.00 AM for 15 minutes at a duration of about 10-30 seconds. The number of egg capsules found in squid houses and various substrates in nature was 1,698 and 1,568 egg capsules. Squid eggs were found at a depth of 1-7 meters, with the most at a depth of 3 meters with 2,718 egg capsules.

Abstract:

We propose a scheme to realize the optimal 1 → 2 universal quantum cloning (UQC) in 2-dimension with superconducting quantum-interference device (SQUID) qubits in a microwave cavity. In our scheme, three-SQUIDs are fixed in a microwave cavity via a Raman transition for their manipulation. Using this method, no transfer of quantum information between the SQUIDs and the cavity is required, the cavity field is only virtually excited and thus the cavity decay is suppressed during the cloning process. Furthermore, our scheme only requires using the two lower flux states of the SQUID system and the excited state is not excited. So the effect of decoherence based on the levels of the SQUID system is possible to minimize.

Abstract:

Scanning Superconducting Quantum Interference Device (SQUID) Susceptometry simultaneously images the local magnetic fields and susceptibilities above a sample with sub-micron spatial resolution. Further development of this technique requires a thorough understanding of the current, voltage, and flux ( I V Φ ) characteristics of scanning SQUID susceptometers. These sensors often have striking anomalies in their current–voltage characteristics, which we believe to be due to electromagnetic resonances. The effect of these resonances on the performance of these SQUIDs is unknown. To explore the origin and impact of the resonances, we develop a model that qualitatively reproduces the experimentally-determined I V Φ characteristics of our scanning SQUID susceptometers. We use this model to calculate the noise characteristics of SQUIDs of different designs. We find that the calculated ultimate flux noise is better in susceptometers with damping resistors that diminish the resonances than in susceptometers without damping resistors. Such calculations will enable the optimization of the signal-to-noise characteristics of scanning SQUID susceptometers.

Abstract:

Les systèmes de télécommunication de type radio logicielle ou "Software Defined Radio" (SDR) exploitent les techniques numériques qui permettent leur reconfigurabilité, que ce soit en termes de fréquence, de bande passante utilisée, ou de méthode de modulation/démodulation des signaux. Ceux-ci nécessitent des architectures permettant la numérisation des signaux analogiques RF à des fréquences d'échantillonnage de plusieurs dizaines de GHz, avec des bandes passantes de plusieurs dizaines de MHz et une résolution supérieure à 10 bits. Ces objectifs sont très difficiles à atteindre avec la technologie actuelle des semi-conducteurs. La logique à quantum de flux magnétique ou logique "Rapid Single-Flux-Quantum" (RSFQ) se présente comme un candidat séduisant pour la conception de tels systèmes.En effet, celle-ci permet d'atteindre des fréquences d'horloge de plusieurs centaines de GHz pour une consommation d'environ 100 nW par porte logique. Le travail de thèse a consisté en la réalisation d'un prototype de chaîne de réception RF analogique-numérique en technologie RSFQ. L'étude et la conception des différents blocs la constituant comme le convertisseur analogique-numérique et ceux de traitement du signal numérisé en aval a été réalisée. Les premiers résultats expérimentaux confirment la fonctionnalité des cellules RSFQ de base constituant le bloc de traitement numérique. La difficulté à faire fonctionner expérimentalement les blocs plus complexes a soulevé la question de la sensibilité des cellules RSFQ aux perturbations magnétiques extérieures. Cette problématique a été étudiée sur des circuits RSFQ simples et a permis de conclure qu'un champ magnétique externe de quelques dizaines de $mu$T était suffisant pour dégrader le fonctionnement de tels circuits. Une solution de prise en compte des effets d'un champ magnétique externe dans le simulateur utilisé a été développée pour anticiper ces problèmes dès la conception. Celle-ci a été validée expérimentalement avec un Superconducting Quantum Interference Device (SQUID)
Information and telecommunication Software Defined Radio (SDR) systems are mainly based on digital techniques, which enable to easily reconfigure them, in terms of frequency, bandwidth and modulation techniques. They can process the information entirely in a digital way, by directly sampling the input RF signal and require analog-to-digital converters with strong performances. Indeed, SDR systems have to work at sampling frequencies of several tens of GHz, with large bandwidths and a suitable resolution ($geq$ 10 bits). Rapid-Single-Flux-Quantum logic (RSFQ) seems to be an interesting solution to design such systems. This technology can reach clock frequencies of several hundreds of GHz with a power consumption of only 100 nW per logic gate. This work deals with the design of a superconductive RF front-end receiver based on RSFQ technology. The study of the different parts of the chain was done, such as the analog-to-digital converter and the signal processing part of the digital signal. Experimental results confirm that all simple RSFQ cells work with correct margins. Complex circuits work with more difficulty, raising the issue of the sensitivity of RSFQ cells to external magnetic disturbances. This point was studied on basic RSFQ cicuits and shows that a magnetic field of about 10 $mu$T is sufficient to spoil the operation of the circuit. Moreover, a solution to take into account magnetic effects in the simulation of the circuits was developed and experimentally validated on a Superconducting Quantum Interference Device (SQUID)

This thesis relates to the analysis and design of a SQUID microscope. Superconductor theory is discussed in depth to provide a thorough understanding of Josephson junctions and of dc SQUID magnetometers. The behaviour and suitability of different types of single-layer dc SQUIDs are looked at. The quality of the superconducting material patterned onto a substrate and the Josephson junction design used affect the behaviour of a practical dc SQUID. Noise and cooling play an integral part in the design and operation of a dc SQUID. The source of noise is looked at in an effort to minimize its effect. Cryocooling is essential to real world operation so different cooling strategies and their consequences are analyzed. This thesis focuses on modeling the behaviour of the dc SQUID to creating a practical system for use inside a SQUID microscope. Operating the dc SQUID with the appropriate electronics will linearize the device, reduce the effect of noise, and create a device with wide bandwidth. Each step in creating a practical system is discussed in detail. Simulations are used to create models predicting the behaviour of the dc SQUID and the electronics. They are then used to design and create practical electronic systems. Measurements are performed on Josephson junctions and dc SQUID magnetometers using the designed electronics. The Josephson junctions behave as predicted and were successfully tested. The dc SQUIDs did not behave as predicted and were not successfully tested. The SQUIDs were damaged, either by a malfunction in the cryocooler or through age related deterioration. A full test of the flux-locked loop was not possible and the dc SQUID was not linearized.

Abstract:

Thesis (MTech (Mechanical Engineering))--Cape Peninsula University of Technology, 2017.
In South Africa, squid fishing vessels need to find and then anchor above benthic squid egg beds to effect viable catches. However, waves acting on the vessel produce a dynamic response on the anchor line. These oscillatory motions produce impact forces of the chain striking the seabed. It is hypothesised that this causes damage to the squid egg bed beneath the vessels. Different mooring systems may cause more or less damage and this is what is investigated in this research. The effect of vessel mooring lines impact on the seabed during squid fishing is investigated using a specialised hydrodynamic tool commercial package ANSYS AQWA models. This study analysed the single-point versus the two-point mooring system’s impact on the seabed. The ANSYS AQWA models were developed for both mooring systems under the influence of the wave and current loads using the 14 and 22 m vessels anchored with various chain sizes. The effect of various wave conditions was investigated as well as the analysis of three mooring line configurations. The mooring chain contact pressure on the seabed is investigated beyond what is output from ANSYS AQWA using ABAQUS finite element analysis. The real-world velocity of the mooring chain underwater was obtained using video analysis. The ABAQUS model was built by varying chain sizes at different impact velocities. The impact pressure and force due to this velocity was related to mooring line impact velocity on the seabed in ANSYS AQWA. Results show the maximum impact pressure of 191 MPa when the 20 mm diameter chain impacts the seabed at the velocity of 8 m/s from video analysis. It was found that the mooring chain impact pressure on the seabed increased with an increase in the velocity of impact and chain size. The ANSYS AQWA impact pressure on the seabed was found to be 170.86 MPa at the impact velocity of 6.4 m/s. The two-point mooring system was found to double the seabed mooring chain contact length compared to the single-point mooring system. Both mooring systems showed that the 14 m vessel mooring line causes the least seabed footprint compared to the 22 m vessel.

Abstract:

Nano-electromechanical systems (NEMS) are an important new class of device, with a growing range of applications, from tests of quantum mechanics through to nanoscale metrology and a vast number of different sensors. Cryogenic operation is also possible, and at low temperatures, nanoscale resonators exhibit quantum behaviour. NEMS resonators require readout of ultra-small, atomic scale displacements. To achieve this at low temperatures we have developed an ultrasensitive nanoSQUID readout of a coupled current-carrying NEMS resonator. The NanoSQUIDs are fabricated by gallium focussed ion beam milling and are based on niobium nanobridge weak links (Dayem bridges). The nanoSQUIDs have low loop inductance and low junction capacitance resulting in high flux and energy sensitivity. This work focusses on the characterisation of the resonator and nanoSQUID after they have been incorporated onto one chip. This is done through nanoindentation to characterise resonators and electronic measurements of the SQUID using a low-temperature preamplifier. It is found that the model used based upon an Euler-Bernoilli beam is correct close the centre of the sample but does not fit data points well close to the contacts. It is found the resonators have Young’s modulus in the range of 3GPa-241GPa. Both beam and paddle-shaped resonators are investigated and the models are made based upon the two different shapes. That for the paddle is based upon the same as the beam but uses a rectangular function to describe the changing area moment of inertia along the length of the resonator. The SQUID devices are characterised and found to have a typical noise floor of 0.2μ 0/pHz. Problems which have arisen due to the orientation of the two magnetic fields and their effect on the SQUID performance are discussed. We consider the geometry and optimum coupling of rectangular and square Si3N4 resonators to matching similar shaped nanoSQUID loops. We also discuss simulations of the nanoSQUID response versus resonator position for both symmetric and asymmetric configurations. It is found that optimal coupling is achieved in the asymmetric case due to the cancelling of the change in flux in the symmetric case. The use of a normal conducting or superconducting resonator is compared. It is found that a superconducting resonator provides a much larger SQUID response when actuated towards the device but cannot be used in the regime due to limitations of the superconducting transition temperature of Al (the resonator) being lower than the non-hysteretic operable temperature of the SQUID. Preliminary measurements are conducted on the coupled devices. It is noted that the signal from the device in the conducting case may be read out at 2! due to the sinusoidal change in flux through the SQUID loop and position of the resonator. The possibility of measuring such a signal is first investigated using a spectrum analyser but it is found the SQUID is pushed to nonlinear regions of its transfer curve. This results in a component of the signal at 2! due to the nonlinearity of the SQUID response. Conditions under which the SQUID is still operating in small signal mode (to preserve linearity of the SQUID response) are considered and from this we conclude there is a need to use phase sensitive detection to achieve optimum sensitivity. This technique is used to conduct the final measurement of the motion of the resonator by the SQUID and a preliminary result is found.

Abstract:

With the development of superconducting quantum interference device (SQUID) detectors for measuring very weak magnetic fields, it has become possible to map those fields generated by electrical activity in humans. New medical diagnostic tools are now emerging using this technology. We describe the historical development of these diagnostic tools. We begin with some experiments which predate the SQUID. Next we give a brief intuitive explanation of SQUID operating principles. We continue the historical descriptions with developments in magnetoencephalography and magnetocardiography. Finally, we move to a newly developing area: SQUID imaging. In SQUID imaging, SQUID measurement and computer processing are combined to provide images of the currents' sources. Analogies to optical imaging systems are shown, and modifications of common characterization tools (PSF and OTF) are presented.

Abstract:

Abstract Scanning superconducting quantum interference device (SQUID) microscopy using high-TC SQUID sensor has been slowly gaining acceptance in the failure analysis (FA) community as a number of silicon device manufacturers are applying the tool and technique to an ever-broadening spectrum of silicon technologies for detecting the location of leakage and short failures by imaging the current path through the die and package. This paper will present the application of scanning SQUID microscopy to short isolation on die and explore the integration of this technique into the FA flow. From the examples presented in this paper, it can be seen that die level short isolation has been possible even when the separation from SQUID sensor to current is about 800-900µm. Several potentially useful techniques that will increase the accuracy of locating the die level short nondestructively are also discussed.
