Résumé :

Abstract An array of twelve 0.28 kg lithium molybdate (LMO) low-temperature bolometers equipped with 16 bolometric Ge light detectors, aiming at optimization of detector structure for CROSS and CUPID double-beta decay experiments, was constructed and tested in a low-background pulse-tube-based cryostat at the Canfranc underground laboratory in Spain. Performance of the scintillating bolometers was studied depending on the size of phonon NTD-Ge sensors glued to both LMO and Ge absorbers, shape of the Ge light detectors (circular vs. square, from two suppliers), in different light collection con

Abstract The Terahertz (THz) region lie in the range 0.1 THz to 10 THz. It can pass easily through fog, smoke, thin walls, and clothes and be focused as a light wave to create images of objects. Terahertz waves are applied in imaging technology, such as safety, navigation, and non-destructive evaluation (NDE) technique used for materials analysis.

Résumé :

Bolometers are low temperature particle detectors with high energy resolution and detection efficiency. Some types of bolometric detectors are also able to perform an efficient particle identification. A wide variety of radiopure dielectric and diamagnetic materials makes the bolometric technique favorable for applications in astroparticle physics. In particular, thanks to their superior performance, bolometers play an important role in the worldwide efforts on searches for neutrinoless double-beta decay. Such experiments strongly require an extremely low level of the backgrounds that can easi

This review aims to cover the history and recent developments on cryogenic bolometers for neutrinoless double beta decay (0ν2β) searches. A 0ν2β decay observation would confirm the total lepton charge non-conservation, which is related to a global U(1)LC symmetry. This discovery would also provide essential information on neutrino masses and nature, opening the door to new physics beyond the Standard Model.

Two-neutrino double β decay can create an irremovable background even in high energy resolution detectors searching for neutrinoless double β decay due to random coincidence of 2ν2β events in the case of poor time resolution. Some possibilities for suppressing this background in cryogenic scintillating bolometers are discussed. It is shown that the present bolometric detector technologies enable one to control this form of background at the level required to explore the inverted hierarchy of the neutrino mass pattern, including the case of bolometers searching for the neutrinoless double β dec

The characteristics of voltage biased HTc bolometers have been analysed by numerically solving the heat continuity equation of the system for ohmic and non-ohmic behaviour. The solutions show that the time constant and the linearity range of response depend strongly on biasing condition. For a bolometer in ohmic regime and operating in strong electrothermal feedback, the time constant can be reduced of more of one order of magnitude and linearity range increased of about 100 times with respect to the same device biased at low bias voltage.

Résumé :

Abstract A prototype version of the Q & U bolometric interferometer for cosmology (QUBIC) underwent a campaign of testing in the laboratory at Astroparticle Physics and Cosmology laboratory in Paris (APC). The detection chain is currently made of 256 NbSi transition edge sensors (TES) cooled to 320 mK. The readout system is a 128:1 time domain multiplexing scheme based on 128 SQUIDs cooled at 1 K that are controlled and amplified by a SiGe application specific integrated circuit at 40 K. We report the performance of this readout chain and the characterization of the TES. The readout system

Résumé :

Image analysis-based measurement techniques are gaining popularity thanks to their ability of measuring different kinds of mechanical fields without interfering with the measurand. Thermoelastic Stress Analysis is a full field, non-contact technique that uses IR images and the principle of thermoelasticity to measure stress distributions. The low amplitude of the temperature variations and the high frequency excitations required, make it mandatory to use fast and expensive IR imaging systems. Using systems based on micro-bolometers instead of photonic sensor, could significantly reduce the cos

Résumé :

A comparative analysis of the characteristics of the main types of bolometers is indicated in the article. The constructive solution of an uncooled thermal detector of the bolometric type, formed using the technology of microelectromechanical systems, is studied. By means of computer simulation in modern computer-aided design systems in microelectronics, a static mechanical analysis was performed to assess the effect of mechanical stresses arising in structural materials during their formation on the magnitude of deformation. It has been established that to ensure the normal functioning of the

Résumé :

TeO2 crystals have proven to be superb bolometers for the search of neutrinoless double beta decay in many respects. However, if used alone, they do not exhibit any feature that allows to discriminate an alpha energy deposit from a beta/gamma one. This fact limits their ability to reject the background due to natural radioactivity and eventually affects the sensitivity of the search. In this paper we show the results of a TeO2 crystal where, in coincidence with its bolometric heat signal, also the luminescence light escaping the crystal is recorded. The results show that we are able to measure

We present a prototype scintillating bolometer for the search for neutrino-less double β decay of 100Mo, consisting of a single ≈5 g ZnMoO4 crystal operated aboveground in the 20–30 mK temperature range. The scintillation light is read out by two thin Ge bolometers. The phonon signals are collected by NTD Ge thermistors. The ZnMoO4 crystal was grown with an advanced method (low-thermal-gradient Czochralski technique) and after purification of molybdenum. The results are very encouraging: the intrinsic energy resolution of the heat channel is ≈800 eV FWHM, the α/β rejection factor (crucial for

It has been established that in plates made of hot-pressed ferroelectric ceramics PZT-19 ([Formula: see text]C), after metal electrodes from Ag are burned into opposite surfaces with different depths of mechanical damage, counter-directional stationary deformation gradients and, accordingly, internal electric displacement fields create a stationary flexoelectric effect. As a result, unpolarized ceramics below the Curie temperature become a pyroelectric, and above it become a pyroelectric bolometer.

Photographs in optical and X-ray wavelengths as well as a bolometirc picture are also obtained and compared with one another. When the temperature at the inner region of the disk is some 107 K, the X-ray and bolometric images are rather contrasty, while the brightness of the disk in the optical image gradually decreases from the inner region toward the fringe. X-ray light curves when the relativistic accretion disk is eclipsed by its companion are calcula

InfraRed Focal Plane Arrays (IRFPAs) are crucial components in a wide range of applications, including night vision, thermal imaging and gas sensing. Among the various types of IRFPAs, micro-bolometer-based ones have gained significant attention due to their high sensitivity, low noise and low cost. However, their performance is heavily dependent on the readout interface, which converts the analog electrical signals provided by the micro-bolometers into digital signals for further processing and analysis.

Résumé :

ABSTRACT Bolometric luminosity is an important quantity that tells us the radiative energy output of an active galactic nucleus (AGN). A common way to estimate bolometric luminosity is to use ultraviolet (UV) or optical luminosities as its proxies, but the UV- or optical-based-bolometric luminosity estimators can be easily affected by dust extinction. In this study, we present new methods for estimating bolometric luminosities using infrared (IR) hydrogen Paschen and Brackett line luminosities to alleviate the dust extinction effects. We show that there exist tight correlations between the bol
