The JT-60SA Tokamak is provided with a cryogenic system with a refrigeration capacity of 9 kW (eqv).
Therefore, the target was emptied to recover the [18O]2 gas using a cryogenic system and a vacuum was created inside the target to remove traces of [18O]oxygen.
A cryogenic system has been designed and tested that reaches a temperature below 1.1 K, with an rms temperature stability of 25 μK.
A cryogenic system has been designed to make a thin target of solid hydrogen isotopes usable under vacuum, with a particle beam.
A cryogenic system for CDEX-10 has been designed and constructed.
The problem of the high-voltage insulation gets to be solved by this cryogenic system, and also the period of the filling with liquid nitrogen can be obviously prolonged due to the closed self-circulation, even without further extra filling.
Moderators are controlled by a cryogenic hydrogen system that has a hydrogen relief system, which consists of high and low pressure stage of manifolds, a hydrogen vent line and a stack, in order to release hydrogen to the outside safely.
In order to secure against unexpected emergencies and solve the problem of LN2 consumption, a hybrid cryogenic system was designed and installed.
Experimental efficiency is increased by a cryogenic exchange system for 3.2 mm rotors within the 89 mm bore.
Natural remanent magnetization (NRM) measurements with stepwise alternating field (AF) demagnetization were performed using a cryogenic magnetometer system with an in-line static AF demagnetizer (2G Enterprises model 760, Applied Physics Systems, Inc., Mountain View, CA, USA) in a magnetically shielded room of GSJ, AIST.
