Quench Simulation of REBCO Cable-in-Conduit Conductor With Twisted Stacked-Tape Cable

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Rainer Wesche

Quench protection is a critical issue for magnet using high-temperature superconducting (HTS) materials such as REBCO. For cable-in-conduit conductor (CICC) with twisted REBCO tapes, which is considered for high-current HTS conductor for fusion magnet, the ...

2020

Molybdenum ditelluride (MoTe2) is attracting considerable interest since it is the archetypal type-II Weyl semimetal and a candidate for topological superconductivity. We investigate the superconducting phase diagram of two MoTe2 polymorphs using the ab in ...

Understanding the electro-thermal behavior of high-temperature superconductor (HTS) materials is a critical aspect for designing efficient and reliable applications. In order to optimize cost and performance, one needs to understand the role played by the ...

Thermodynamic anomaly above the superconducting critical temperature in the quasi-one-dimensional superconductorTa4Pd3Te16

Philip Johannes Walter Moll

We study the intrinsic electronic anisotropy and fermiology of the quasi-one-dimensional superconductor Ta4Pd3Te16. Below T∗=20 K, we detect a thermodynamic phase transition that predominantly affects the conductivity perpendicular to the quasi-one-dimensi ...

Cryogenic Fab-on-a-Chip Sticks the Landing

Matthias Imboden, Han Han

Using a microelectromechanical systems (MEMS)-based Fab-on-a-Chip, we quench-condense lead thin-films. Suppressing the formation of lead islands makes it possible to grow a homogeneous and continuous film as thin as 2 nm, without the use of an adhesion lay ...

Quench Detection and Protection of the HTS Insert Coils

Natalia Hanna Glowa

As a result of extremely high upper critical fields B_c2, high temperature superconductors (HTS) have the potential to be used as high field insert coils in magnet systems where the background field is provided by low temperature superconductors (LTS) with ...

Critical Current Oscillations in the Intrinsic Hybrid Vortex State of SmFeAs(O,F)

Philip Johannes Walter Moll

In layered superconductors the order parameter may be modulated within the unit cell, leading to nontrivial modifications of the vortex core if the interlayer coherence length ξc(T) is comparable to the interlayer spacing. In the iron pnictide SmFeAs(O,F) ...

We investigate the mechanical properties of a doubly clamped, double-layer nanobeam embedded into an electromechanical system. The nanobeam consists of a highly pre-stressed silicon nitride and a superconducting niobium layer. By measuring the mechanical d ...

Irreversible Degradation in Nb3Sn Cable in Conduit Conductors

Ciro Calzolaio

One of the biggest goals for the international thermonuclear experimental reactor (ITER) is the steady state operation. For this reason all its coils will be superconducting and Nb3Sn material is used for both the toroidal field (TF) and the central soleno ...

Transition from slow Abrikosov to fast moving Josephson vortices in iron pnictide superconductors

Philip Johannes Walter Moll

Iron pnictides are layered high Tc superconductors with moderate material anisotropy and thus Abrikosov vortices are expected in the mixed state. Yet, we have discovered a distinct change in the nature of the vortices from Abrikosov-like to Josephson-like ...
