| 内容記述 | In this paper, the JT-60SA cryogenic system and the results of the commissioning and annual operations are summarized. During the commissioning of the cryogenic system, performances for each component and the automatically controlled operation sequence have been confirmed. Notably, mitigation of cryogenic heat load fluctuations in large superconducting tokamak machines is essential. The automatic mitigation of variable loads becomes a challenging control to perform on large scale refrigeration system for tokamaks. Hence, for JT-60SA cryogenic system, an active control method for cryogenic heat load fluctuation has been successfully tested. We have established an active control method for cryogenic heat load fluctuation in the JT-60SA cryogenic system. The commissioning was completed toward an integrated commissioning test of the whole JT-60SA system for the first plasma discharge. | |||||
