Novel Cryogenic and HTS Technologies

Oral

Interest in high-temperature superconducting (HTS) technologies is surging across fusion energy, large electric transport, data centers, and electric utilities due to their unmatched power density. Notably, liquid hydrogen (LH2) platforms simplify HTS integration by utilizing LH2 at 20 K as an effective cryogenic heat sink. However, the advancement of these technologies is heavily constrained...

Oral

A high-capacity closed-cycle 1 K cryostat based on a capillary Joule–Thomson (J–T) expansion stage is developed and experimentally characterized for low-temperature physical property measurements of superconducting detectors. The cryostat achieves a base temperature of 1.37 K and provides a cooling power of approximately 30 mW at 1.54 K. By employing a lower-impedance capillary, the cooling...

Novel Cryogenic and HTS Technologies

Oral

Viable nuclear fusion reactors will need to gather in a constrained space a wide variety of elements related to the fuel cycle, and plasma initiation, shaping, and positioning, amongst others. Tokamaks rely upon several sets of coils for plasma control [1]. The large currents circulating through those magnets make the use of superconductors advantageous. For practical purposes, superconductors...

Novel Cryogenic and HTS Technologies

Oral

Turbomachinery based cooling systems have advantages compared to other cooling systems in terms of low maintenance due to the oil-free gas bearing, low micro-vibration emission as they are continuous flow machines with well-balanced rotor, and the low specific energy consumption (W per W of cooling) due to their high efficiency. In a first concept, they are applied as turbo compressor and...
