Abstract

The invention discloses a low energy big flow and strong irradiation device for materials. The key points of the technical scheme of the device are as follows: the device comprises an air supply system, an air pressure monitoring device 2, a plasma generation system, a sample table 13, a laser heating system 6, a temperature measurement system 9, a vacuum extraction system 5, a water-cooling circulating system 4 and a power supply system. When the material surface is processed by the device, the irradiation environment of a nuclear fusion reactor can be effectively simulated, and further, changes of characteristic, structure and function of the irradiated material can be studied.

Description

technical field [0001] The invention relates to a low-energy, high-flow, high-intensity irradiation device capable of simulating the irradiation environment in the nuclear fusion reaction process, such as the interaction between high-temperature, low-energy ions and the first wall material of a fusion reactor, in the field of nuclear fusion tokmak NBI technology. Background technique [0002] The International Thermonuclear Experimental Reactor (ITER) program is one of the largest international scientific and technological cooperation programs for large-scale scientific engineering in the world today, and it is also the largest international scientific and technological cooperation program that my country has participated in so far. , Russia, the United States and other major nuclear powers and technological powers in the world will participate together. Approved by the State Council in 2007, my country established the "China International Thermonuclear Experimental Reactor (...
