Description
technical field [0001] The invention belongs to the field of vacuum chambers, in particular to a high-power long-pulse neutral beam injector vacuum chamber. Background technique [0002] Neutral beam (NBI) injection heating is one of the main auxiliary heating methods for magnetic confinement fusion experimental devices. Major large and medium-sized tokamaks in the world are equipped with strong neutral beam systems. With the expansion of fusion experimental equipment and the deepening of fusion plasma experimental research, the injection power, beam particle energy and beam pulse width required by the neutral beam heating system continue to increase, and the resulting engineering and technical difficulties are also increasing. In order to realize the physical goal of the upgraded HL-2M device of the HL-2A device, three new NBI beamlines need to be developed, and the power of each NBI heating beamline can reach 5MW. [0003] Different parts of the neutral beam injector have...
