Abstract
The invention relates to a method and device for pulsed charge cooling of a component of a Tokamak. The method uses a refrigeration device that subjects a working fluid such as helium to a work cycle including: compression, cooling, and decompression, as well as heat exchange with the member and heating. The refrigeration power produced by the refrigeration device is increased to a relatively high level when the Tokamak is in a plasma generation phase and is decreased to a relatively low level when the Tokamak is no longer in a plasma generation phase. The increase in refrigeration power produced by the refrigeration device is automatically triggered in response to a signal produced during a step for starting plasma in the Tokamak.
