The Infinity One Fusion machine is an HTS-based stellarator currently being designed by Type One Energy Group Inc. Several components of this machine such as its superconducting magnets, current leads, thermal shields, vacuum pumping system, and fuel injection system require cooling at cryogenic temperatures. The cryogenic distribution system is responsible for delivering helium at the...
This paper explores the cooling demands of high-temperature superconducting microwave receiver front-ends, specifically aiming at microstrip antennas within a cryogenic subsystem. Firstly, a transient heat transfer model was developed based on experiments with a 3W@77K pulse tube cryocooler. Then, a cryogenic system with a 15W@77K cryocooler was designed from this model, achieving a cooling...
High temperature superconducting (HTS) power cables offer promising solutions for electric aircraft and ships with power demands of up to 50 MW and 100 MW, respectively. However, their cryogenic cooling requirements present challenges. While liquid nitrogen is used for the grid applications of HTS cables, its limited temperature range (63-77 K) and asphyxiation risks make it suboptimal for...
As the demand for electric energy continues to grow, high-
However, all practical superconducting materials still require operation at cryogenic temperatures. These...
