Abstract:
Superconducting Josephson junctions have major advantages as detectors of millimeter wave radiation. Frequency of the radiation can be easily derived from the Shapiro steps of the current-voltage characteristics. However, system performance is highly sensitive to impedance mismatch between the antenna and the junction; therefore, optimization is essential. We analyzed and implemented an improved antenna structure, in which the junction is displaced from the antenna center and placed between the ends of two matching strips. Based on theoretical analysis and advanced electromagnetic simulations, we optimized strip dimensions, which affect both the detection magnitude and the frequency of the reflection coefficient dip. Accordingly, two Au bow-tie antennas with different matching strip widths were fabricated. Superconducting Yttrium Barium Copper Oxide (YBCO) thin films were deposited exactly at the bicrystal substrate misorientation points, forming Josephson junctions at the ends of two matching strips. We found a very high correlation between the simulations and the response to Radio Frequency (RF) radiation in the range of 145–165 GHz. Experimental results agree extremely well with the design, showing best performance of both antennas around the frequency for which impedance matching was derived.

O estudo do comportamento de vórtices em supercondutores de tipo II com centros de aprisionamento (CAs) vem atraindo muita atenção nas últimas décadas devido a possibilidade de aumento da corrente crítica, assim como pela variedade de comportamentos que o sistema pode apresentar. Muito foi feito nos últimos anos na tentativa de compreender os mecanismos de aprisionamento, incluindo estudos de filmes infinitos sob influência de arranjos periódicos e quase-periódicos focando nos efeitos de comensurabilidade, correntes críticas e fases dinâmicas. No entanto, quando se trata de fitas supercondutoras muito trabalho ainda é necessário, especialmente para verificar como os CAs influenciam o sistema. Neste trabalho, foi simulado computacionalmente, utilizando técnicas de Dinâmica Molecular, o comportamento dinâmico de vórtices no interior de uma fita supercondutora do tipo II sob a influência de CAs com distribuição aleatória, hexagonal e dois tipos de arranjos conformes. A simulação foi feita considerando fitas imersas no plano xy, finita em x e infinita em y, com um campo magnético aplicado perpendicularmente ao plano das fitas e temperatura nula. Como resultado, encontramos que a fita com aprisionamento aleatório apresentou, na média, um decaimento suave da força de depinning (força necessária para libertar os vórtices dos CAs) em função do campo aplicado. Além disso, foi observada a presença de vórtices intersticiais fracamente ancorados, resultando em baixos valores de força de depinning. Já a fita com arranjo hexagonal apresentou efeitos significativos de comensurabilidade apenas no primeiro matching field, onde há um grande aumento da força de depinning, diferentemente do observado em filmes supercondutores infinitos, onde vários picos de comensurabilidade na corrente crítica são observados. Para os arranjos conformes, a força de depinning muda muito pouco em função do campo aplicado apresentando uma leve tendência decrescente, o que está de acordo com o que foi observado em filmes infinitos. Este comportamento está associado ao gradiente de defeitos e a simetria hexagonal que a rede conforme preserva, tornando o aprisionamento mais efetivo. Em um dos arranjos conforme foi obtido um aumento significativo nas forças de depinning em baixos campos, quando comparado aos outros arranjos. Com relação aos regimes dinâmicos, em fitas os vórtices tendem a formar canais devido a influência da corrente superfícial, que reduz o movimento transversal dos vórtices, diferentemente do observado em filmes infinitos.
The behavior of vortices in type II superconductors in the presence of artificial pinning centers has attracted much attention in the last two decades, due to the possibility of enhancing the critical currents, as well as the variety of behaviors that the system can exhibit. Much has been done in recent years to understand the pinning mechanisms, including studies of infinite films under the influence of periodic and quasi-periodic arrays focusing on the commensurability effects, critical currents and vortex dynamic phases. However, when it comes to superconducting strips a lot of work is still required, especially when the system is under the influence of pinning centers. In this work, we study the dynamic behavior of vortices inside a type II superconducting strip in the presence of pinning centers with random distribution, hexagonal and two types of conformal arrays. The simulation was performed considering strips using Molecular Dynamics technique, each with different arrays of defects, immersed in the xy plane, with finite dimension in x and infinite in y, under a magnetic field applied perpendicular to the plane of the strips and zero temperature. As a result, it was found that the strip with random pinning distribution showed a gentle decay of the depinning forces as a function of the applied field. In addition, the presence of weakly pinned interstitial vortices was observed, resulting in low values of depinning force. The hexagonal array showed significant commensurability effects only at the first matching field, where there is a great increase of the depinning force, unlike that observed in infinite superconducting films, where several commensurability peaks in the critical current is observed. For the conformal arrays, we observed a depinning force stability as a function of the applied field, which agrees with what has been observed in infinite films. This stability is associated to the gradient distribution of defects in the central region of the sample associated with sixfold symmetry that the conformal transformation preserves, resulting in a more effective pinning. In one of the conformal lattices, a significant increase in the depinning forces in low fields was obtained when compared to the other arrays. Concerning to the dynamic regimes, vortices in strips tend to form well defined channels due to the influence of the surface current, which reduces the transverse motion of the vortices, different to that observed in infinite films.

Superconducting magnets will play a central role for the success of the International Thermonuclear Experimental Reactor (ITER). ITER is a current driven plasma experiment that could set a milestone towards the demonstration of fusion as a source of energy in the future. Cable-in-Conduit is the typical geometry for the conductor employed in superconducting magnets for fusion application. The cable is composed of over 800 strands. Once energized, the magnets produce an enormous electromagnetic force defined by the product of the current and the magnetic field. The strands move under the effect of this force, and the force accumulates against one side of the conduit thereby pressing transversally against the strands. The experiment proposed here has the goal of assessing the functionality of the apparatus designed to study the effect of transverse load on a cable composed of 36 superconducting strands (with a 3x3x4 pattern) by mechanically simulating the ITER Lorentz stress condition. The apparatus was assembled at MIT and preliminary tests at 77 K and room temperature were made to improve the design prior to carrying out the actual experiments. These were done at the National High Magnetic Field Laboratory (NHMFL) located in Florida. Ideally, the transverse conditions simulating the ITER conditions should be created by Lorentz forces due to current and magnetic field. Unfortunately to create such a high level of stress, currents higher than the power supply capability at NHMFL (10 kA) would be required. This is the driving reason to have an apparatus simulating the same stress condition mechanically.
The first test was conducted in October 2005. It was possible to test the structure and its range of operation. Critical current measurements were made as a function of different fields. However during the first measurement, under the loading conditions, the sample was irreversibly damaged and no other measurements were possible. The successful test of the structural behavior of the apparatus motivated a second test carried out in January 2006. With the improvements made between the two experiments, it was possible to successfully measure the degradation of the cable as a function of the transverse pressure applied, measuring degradation as high as 50% with a transverse load of 100 MPa. The ultimate goal of these studies is to characterize the critical current behavior as a function of transverse load in order to predict the response of a full sized Cable-in-Conduit. The work in this thesis was used to explore a setup for measurements and measurement technique. A set of empirical equations describing the behavior of full size cables is needed and should be addressed with a new project that extends the work done so far.

Abstract:
Nous présentons ici, l'analyse détaillée et l'étude de la stabilité de nouvelles solutions de type vortex dans le secteur bosonique de la théorie électrofaible. Les nouvelles solutions généralisent le plongement des solutions d'Abrikosov-Nielsen-Olesen dans la théorie électrofaible et reproduisent les résultats précédemment connus. Les vortex, génériquement porteurs d'un courant électrique, sont constitués d'un coeur massif de bosons chargés W entouré d'une superposition non-linéaire de champs Z et Higgs. Au loin la solution est purement électromagnétique avec un potentiel de Biot et Savart. Les solutions sont génériques de la théorie et existent en particulier pour les valeurs expérimentales des constantes de couplage. Il est en particulier démontré que le courant dont l'échelle typique est le milliard d'Ampères peut être arbitrairement grand. Dans un second temps la stabilité linéaire des vortex supraconducteurs vis-à-vis des perturbations génériques est considérée. Le spectre de l'opérateur de fluctuations est étudié qualitativement. Lorsque des modes instables sont détectés, ils sont explicitement construits ainsi que leurs relations de disperion. La plupart des modes instables sont supprimés par une périodisation du vortex. Il subsiste cependant un unique mode instable homogène. On peut espérer qu'un tel mode puisse être supprimé par des effets de courbure si une portion de vortex est refermée afin de former une boucle stabilisée par le courant électrique.

Nous presentons les premiers resultats obtenus avec un dispositif experimental permettant de changer la contrainte uniaxiale continument a tres basse temperature. Le principe de l'appareil consiste a controler la pression d'helium appliquee sur un soufflet metallique connecte thermiquement a la boite de melange d'un refrigerateur a dilution. Nous etudions l'effet de la contrainte uniaxiale, appliquee selon l'axe c du compose tetragonal uru#2si#2. Nous trouvons que la temperature de transition supraconductrice t#c varie de facon parabolique en fonction de la contrainte #c avec une pente de 76 mk/kbar a #c = 0 kbar et une pente nulle a 6. 5 kbar. La temperature de transition antiferromagnetique t#n varie lineairement en fonction de la contrainte avec une pente egale a 32 mk/kbar. Nous rapportons les premieres mesures de l'evolution du gap des excitations de la phase antiferromagnetique en fonction de la contrainte uniaxiale selon l'axe c. Il decroit lineairement avec une pente de 0. 63 k/kbar. Grace aux mesures de champ critique, nous donnons la premiere estimation de la croissance de la masse effective avec la contrainte selon l'axe c, m*(6. 5 kbar) = 1. 07 m*(0 kbar). Pour le compose hexagonal upt#3, nous confirmons que la temperature de transition supraconductrice t#+#c decroit, d'abord avec une pente de 14. 71. 5 mk/kbar, pour une contrainte appliquee suivant l'axe c inferieure a 2 kbar puis decroit, avec une pente de 5. 20. 7 mk/kbar, pour des contraintes superieures. En variant de 0 a 8. 4 kbar la contrainte #a appliquee selon l'axe a, nous trouvons que la temperature t#+#c decroit regulierement avec une pente de 2. 00. 7 mk/kbar. A partir de l'evaluation du coefficient a de la loi = #0+at#2 et de la pente du second champ critique a bas champ, nous trouvons que la masse effective augmente avec la contrainte suivant l'axe c et diminue avec la contrainte suivant l'axe a:m*(#c = 6. 5 kbar) = 1. 26 m*(#c = 0 kbar) ; m*(#a = 6. 5 kbar) = 0. 86 m*(#a = 0 kbar).

Abstract:
Due to the continuous resources’ reduction and cost increase of conventional fossil fuel along with the global trend to decrease the greenhouse effect, clean energy production from renewable sources has been given a global great concern. Among renewable energy sources, wind energy conversion systems have received a worldwide notable attention. It is expected that more than 10% of the global electricity demand will to be generated by wind energy conversion systems by the year 2020. During their early implementation stage, wind turbines were to be disconnected during abnormal and fault conditions within the electricity grid it is connected to. Owing to the fact that current wind installations supply a significant portion of the load demand, disconnecting windfarms may lead to business interruption and discontinuity of power supply to the end user. As such, transmission line operators have developed strict grid codes that wind turbine generator must meet to maintain its connection to support the grid during various fault conditions. To comply with these codes, flexible AC transmission systems have been widely used with current wind energy conversion systems to modulate reactive and/or active power at the point of common coupling of the wind turbine generator and the grid. This book presents the applications of various flexible ac transmission system devices to wind energy conversion systems. Devices such as unified power flow controllers, superconducting magnetic energy storage and static synchronous compensator are covered in this book. Topologies, control systems along with case studies of the aforementioned devices are presented and discussed. This book will be useful for postgraduate research students, upper-division electrical engineering students and practicing engineers.

Abstract:
Abstract An analytical thermal stress calculation and an in situ thermal stress measurement are developed at low temperatures (from room temperature to liquid helium temperature) on a cylindrical specimen made from an inner bulk niobium wall and a copper alloy VPS coating. This kind of structure is proposed for superconducting cavities in order to reduce the cavity frequency shift due to Lorentz forces. Since the superconducting cavity works at liquid helium temperature (below 4 K) and the niobium thermal expansion ratio is very different from the thermal expansion ratio of copper, thermal stress evaluations during the cool down are necessaries. The experimental approach consists in two series of measurements, the first series of measurements is performed at bulk niobium, bulk copper and thermal sprayed copper since the use of strain gage at liquid helium temperature is unknown from the manufacturer and the behaviour of the strain gage on the copper alloy coating is also unknown, the thermal compensation of strain gage from helium temperature to room temperature is imperative. Then the strain measurements are realized at inner surface (bulk niobium substrate) and outside (copper alloy VPS coating) of the cylindrical specimen. The analytical calculation takes into account non linear thermal expansivities of the materials, the calculated prediction of thermal stress is verified by measurement, a first observation on the copper alloy coating thermal expansion behaviour at low temperatures is established. Key words: thermal spray coating, thermal stress calculation and measurement, liquid helium temperature, superconducting radiofrequency cavities stiffening

Abstract:
A new design code has been developed for construction and operation/maintenance of the International Thermonuclear Experimental Reactor (ITER). A superconducting magnet system is one of the key components of ITER and its design code includes new cryogenic materials and design approach with taking account of unique features of a performance of the superconducting magnet. The new materials are nitrogen strengthened austenitic stainless steels, which have a yield strength (Sy) of over 1000 MPa and fracture toughness (KIc) of over 200 MP√m at liquid helium temperature (4K). The feature of the design approach is use of the allowable stress defined by only 2/3 Sy measured at 4K. A concept and reliability of the new design approach using new cryogenic materials for the ITER superconducting magnet system are discussed in this paper.

Abstract:
Superconducting magnets are structures which have an important role in Tokamak-type fusion reactor plants. They are huge and complicated structures exposed to very low temperature, 4K and the methods for keeping their integrity need to be newly developed. To maintain their structural integrity during the plant operation, a procedure for structural design was developed as a part of JSME Construction Standard for Superconducting Magnet. General structures and requirements of this procedure basically follow those of class 1 and class 2 components in light water reactor plants as specified in Section III, Division 1 of the ASME Boiler and Pressure Vessel Code, and include the evaluation of primary stress, secondary stress and fatigue damage. However, various new aspects have been incorporated considering the features of superconducting magnet structures. They can be summarized as follows: (i) A new procedure to determine allowable stress intensity value was employed to take advantage of the excellent property of newly developed austenitic stainless steels. (ii) Allowable stress system was simplified considering that only austenitic stainless steels and a nickel-based alloy are planned to be used. (iii) A design fatigue curve at 4K was developed for austenitic stainless steels. (iv) In addition to the conventional fatigue assessment based on design fatigue curves, guidelines for fatigue assessment based on crack growth prediction were added as a non-mandatory appendix to provide a tool of assurance for welded joints which are difficult to evaluate nondestructively during the service.
