Publication Year: 2017, Article Sequence Number: 1302307
| | PDF (856 KB) | HTML

Test point insertion and set/scan techniques for enhanced testability in superconductive single-flux-quantum (SFQ) logic are proposed here. Test point insertion reduces the overhead of a set/scan chain while maintaining most of the functionality. Multiple ways of replacing costly (in terms of the number of Josephson junctions) SFQ multiplexers with mergers and blocking gates are proposed. The mult... View full abstract»

• ### Modeling Nonlinearity in Superconducting Interdigital Capacitors and Its Effects on Metamaterial Structures

Publication Year: 2017, Article Sequence Number: 1502909
| | PDF (1125 KB) | HTML

Superconducting devices are known to indicate nonlinear behaviors such as harmonic generation and intermodulation distortion even at low input powers. In this paper, a nonlinear equivalent circuit model for a superconducting interdigital capacitor (SIDC) is proposed. A numerical approach based on a 3-D finite-element method is used to compute the current distribution in SIDCs. Then, closed-form ex... View full abstract»

Publication Year: 2017, Article Sequence Number: 3602208
| | PDF (505 KB) | HTML

Multiseeded YBaCuO bulk crystallized by melt growth process is usually employed as the levitated magnet in high-temperature superconducting (HTS) maglev system. However, to the state of art, the intergrain supercurrent between different domains in the multiseeded bulk superconductor is much harder to simulate than the intragrain supercurrent in the single-seeded bulk, hindering the numerical study...

• ### Investigation of Adopting Shrink-Fit Multilayered Aluminum Shell in High-Field Common-Coil Accelerator Dipole Magnet

Publication Year: 2017, Article Sequence Number: 4004504
| | PDF (480 KB) | HTML

This paper presents the shrink-fit multilayered aluminum shell (SMAS) used for withstanding large Lorentz force in a 20-T shell-based common-coil accelerator dipole magnet. Finite element analysis (FEA) is carried out to optimize the required shell thickness when a single layer aluminum shell is used to support the 20-T dipole magnet. Also, FEA is carried out to study the performance of a three-la... View full abstract»

• ### Modeling Coil-Pole Debonding in ${rm Nb_{3}Sn}$ Superconducting Magnets for Particle Accelerators

Publication Year: 2017, Article Sequence Number: 4004611
| | PDF (1194 KB) | HTML

Superconducting magnets often experience premature quenches, requiring a training phase to reach the desired current. Mechanical disturbances are considered the main causes of such a behavior. A prestress is applied in order to limit these disturbances, compressing the coil against the winding pole. Measurements show that the prestress is continuously reduced by the electromagnetic forces. In some... View full abstract»

The superconducting magnet system in Hall B being designed and built as part of the Jefferson Lab 12 GeV upgrade requires powering two conduction cooled superconducting magnets-a torus and a solenoid. The torus magnet is designed to operate at 3770 A and the solenoid at 2416 A. Failure modes and effects analysis determined that voltage level thresholds and dump switch operation for magnet protecti... View full abstract»

| | PDF (1675 KB) | HTML

This paper describes the test facility and load test program for a 3-MW high-temperature superconducting (HTS) motor for ship propulsion. The test facility was used to conduct a constant-load test and a variable-load test. The program consisted of the constant-load test, the variable-load test, and the inspection after tests. During the constant-load test, the motor efficiency was measured at vari... View full abstract»

• ### Influence of Substrate Magnetism on Frequency-Dependent Transport Loss in HTS-Coated Conductors

Publication Year: 2017, Article Sequence Number: 6603807
| | PDF (860 KB) | HTML

The magnetism of substrate has significant influence on the transport loss in high temperature superconducting (HTS) coated conductors (CCs). Taking three types of substrates (i.e., nonmagnetic, weakly magnetic, and strongly magnetic) into account, a study on the frequency dependence (in the range of 10-1000 Hz) of transport loss in HTS CCs with these substrates is performed numerically and experi...

• ### Strain Distribution in REBCO-Coated Conductors Bent With the Constant-Perimeter Geometry

Publication Year: 2017, Article Sequence Number: 6604010
| | PDF (1163 KB) | HTML Media

Cable and magnet applications require bending REBa2Cu3O7-δ (REBCO, RE = rare earth) tapes around a former to carry high current or generate specific magnetic fields. With a high aspect ratio, REBCO tapes favor the bending along their broad surfaces (easy way) than their thin edges (hard way). The easy-way bending forms can be effectively determined by the co...

• ### Dendritic Flux Avalanches of the Nonhomogeneous/Granular Superconducting Thin Films: Numerical Simulations

Publication Year: 2017, Article Sequence Number: 8001607
| | PDF (985 KB) | HTML

Superconductors can get unstable in the applications due to its thermomagnetic instability characteristics. Superconducting thin films, fabricated by either the pulsed laser deposition or chemical evaporation, usually show nonhomogeneous or granular microstructures. Thus, nonhomogeneous distribution of the superconducting properties is intrinsically introduced into the thin films. In this paper, w... View full abstract»

The mechanical behaviors of a composite superconducting strand, which is composed of a variety of materials with different mechanical properties, are difficult to be accurately predicted using traditional mechanical methods due to the complex modeling process and difficulties in dealing with the interactions among different materials as well as material failure. In this paper, a three-dimensional ... View full abstract»
