Description

Technical Field

[0001] The invention relates to the technical field of mechanical transmission, and in particular to an adjustable target plate device suitable for high heat load testing in a strong magnetic field environment. Background Art

[0002] The plasma-facing components in the fusion device need to withstand the particle flow and heat flow from the central plasma. The operating environment of the core components facing the plasma, such as the divertor and blanket, is extremely harsh. When studying the interaction process and mechanism between plasma and materials under future fusion conditions, it is necessary to conduct performance tests on the divertor and blanket materials under simulated fusion conditions. During the test, the plasma beam bombards the test target in a vacuum environment to meet the predetermined requirements. The magnets in the test device generate a strong magnetic field to constrain the plasma beam. After the plasma beam is constrained and shaped by the magnetic field and the limiter, the energy is concentrated on a smaller point. In order to achieve the impact effect on the target test surface, the position of the test target needs to be adjusted. At the same time, in order to obtain the comparative impact effects of multiple different materials in the same test, it is necessary to replace the test target without stopping the test.
