97. Role of Cryogenics in Superconducting RF (SRF Technology

Shrikant Pattalwar (UKRI- STFC Daresbury Laboratory)

Big Science including accelerators

Oral

Superconductivity plays a significant role in modern high-energy accelerators as it enables:

• High field magnets for bending, focusing, and wiggling charged particle beams
• High field magnets in large detectors for particle identification from colliders
• Superconducting RF cavities for charged particle beam acceleration

In this talk I will give a briefely describe the role of...

103. Numerical Study of AC Loss in Fast-Ramping REBCO Coils with Micro-Filamentary Tape for Magnetic Refrigeration

Novel Cryogenic and HTS Technologies

Oral

Magnetic refrigeration and hydrogen liquefaction based on the active magnetic regenerator cycle require the applied field to be ramped up and down repeatedly. In a superconducting drive coil the resulting AC loss is dissipated directly into the cryogenic environment, so it competes with the useful cooling power of the device and sets a practical ceiling on the achievable cycle rate. Reducing...

91. Producing neon from liquid-hydrogen cold energy to expand the usable inventory as coolant for HTS applications

Novel Cryogenic and HTS Technologies

Oral

Below the 77 K of liquid nitrogen, the practical liquid-cryogen candidates are essentially three, namely helium, hydrogen, and neon. Among them neon is distinctive. It liquefies near 27 K, possesses an exceptionally high volumetric latent heat, about forty times that of helium and three times that of hydrogen, and, as an inert noble gas, is non-flammable and does not embrittle materials. It...

101. Effect of temperature-gradient orientation on dissipative work in a tandem active magnetic regenerator

Novel Cryogenic and HTS Technologies

Oral

Tandem active magnetic regenerator (AMR) configurations, in which two AMR beds are magnetized and demagnetized in antiphase, are attractive because the magnetic forces acting on the beds largely cancel each other and the mechanical work required to drive the beds is reduced. In our previous force-based evaluation, however, the achieved reduction of the magnetic work was smaller than that...
