Extenuation mechanism of energy pulses in cryogenic distribution system of the fusion devices

Fusion devices with superconducting magnets in tokamak configuration generate energy pulses because of their configuration and operating nature. Deposition of energy into magnet system and in turn to the cryogen is primarily dependent on plasma pulse duration and secondarily on the process of heat transfer. The thermodynamic parameters of the cryogen vary during the plasma pulse, causing a dynamically unbalanced condition, which need to be attenuated to give rise to a stable operating condition. Process simulation approach with modeling and associated results including performance comparison of various configurations of distribution system has been realized to achieve the most suitable scheme.
