Description

technical field [0001] The invention relates to the field of supporting facilities used by nuclear fusion experimental equipment, in particular to a device for efficiently transporting plasma of nuclear fusion experimental equipment. Background technique [0002] At present, the global energy demand is increasing sharply. Among many new energy sources, nuclear fusion energy is considered to be one of the most potential sustainable energy sources due to its high efficiency and cleanliness. Therefore, all industrial powers in the world are now conducting continuous research on nuclear fusion. Great progress has been made. In the nuclear fusion experimental equipment, the plasma is pinched to form a beam spot with a certain diameter, and then irradiated on the sample. After the action of related facilities, the divertor on the nuclear fusion experimental equipment discharges the impurities inside the plasma, so that the sample nucleus The heat of fusion energy is released to d...

Problems solved by technology

Existing nuclear fusion experimental equipment only adopts a fixed-output magnetic confinement device, and the two coaxially distributed solenoid coils of the magnetic confinement device generate a magnetic field formed by the magnetic force lines along the axis of the solenoid coil to confine the plasma. In actual work, the magnetic force line will run out of the magnetic confinement device from the middle axis direction of the solenoid coil at both ends, and close the magnetic force line loop outside the magnetic confinement device, so that the plasma generated by the plasma source of the nuclear fusion experimental equipment will run out along the magnetic force line circuit. Plasma loss makes the subsequent plasma beam transported to the surface of the sample have low density and low ionization rate, which cannot meet the processing requirements of fusion materials. Moreover, during work, the operator cannot observe the ion beam bombardment of the sample at any time. It is impossible to adjust the appropriate magnetic field output strength in time according to the observed bombardment of the sample, so that the plasma beam can achieve the best output density and maximum ionization rate under the appropriate magnetic field strength
