Abstract

The invention belongs to the plasma discharge technology, and particularly relates to a superheated water circulation loop for tokamak vacuum baking, which comprises an electric heater, an expansion water tank, a water pump and a plurality of regulating valves, the electric heater and the expansion water tank are connected in series through a pipeline, a plurality of water pumps connected in parallel are installed on a water outlet pipeline of the expansion water tank, an inlet of the electric heater is connected with a load, and an adjusting bypass is arranged between a parallel outlet of the water pumps and the inlet of the electric heater. And the cooled circulating water is heated by the electric heater again, so that a complete cycle is completed. Heat can be fully provided, internal components such as the vacuum chamber and the divertor are reasonably heated, impurities, hydrocarbon and water vapor adsorbed by materials of the vacuum chamber body and the internal components are effectively removed, and a clean high-vacuum environment is provided for plasmas.

Description

technical field [0001] The invention belongs to the plasma discharge technology, and in particular relates to a superheated water circulation circuit used for vacuum baking of a tokamak. Background technique [0002] During the plasma discharge experiment of the tokamak device, it is necessary to provide high-quality ultra-high vacuum conditions for the plasma operation. In order to achieve the vacuum environment required for the plasma operation, the conventional vacuuming method can no longer meet the demand, and it needs to be baked. The internal components such as the vacuum chamber and the divertor are processed in the same way. [0003] The vacuum baking system is a heating system designed for heating and degassing internal components such as the vacuum chamber and divertor of the tokamak device. The performance of the system will directly affect the quality of the plasma and the safety and working life of the vacuum chamber. The baking system removes impurities, hydr...
