摘要： A method for the pulsating load refrigeration of a component of a Tokamak using a refrigeration device subjecting a working fluid to a working cycle. At least one “periodic and symmetrical” operating mode of the Tokamak includes an operating mode in which plasmas of preset duration Dp are generated periodically with intervals of duration Dnp between two successive plasmas. Dnp=Dp±30%. The cooling device cooling power is increased to a relatively high level in a plasma generation phase and reduced to a relatively low level when the Tokamak is no longer in a plasma generation phase. The refrigerating power variation brings gradual increases and reductions in refrigerating power. The increase in the refrigeration device refrigerating power is triggered in advance, in response to a signal (S) generated during a plasma starting step before the thermal load on the component increases.

摘要： 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.
