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-current radiation device capable of simulating the radiation environment in the nuclear fusion reaction process, such as the interaction of high temperature, low-energy ions and the first wall material of a fusion reactor in the technical field of nuclear fusion tokmak NBI. Background technique [0002] The International Thermonuclear Experimental Reactor (ITER) program is one of the world’s largest large-scale scientific engineering international science and technology cooperation programs, and it is also the largest international science and technology cooperation program that my country has participated in. It has attracted China, the European Union, India, Japan, and South Korea. , Russia, the United States and other major nuclear powers and technological powers in the world participated in the joint efforts. In 2007, my country established the "China International Thermonuclear Experimental Reactor (ITER) Speci...
