Abstract

Abstract: The multi-dipole chamber is applied in this paper to simulate the existence of helium neutral particles near the divertor of a fusion reactor. Laser-induced fluorescence diagnostic is used to directly measure the velocity distribution of helium neutral particles. Additionally, the calibration of the measuring area's wavelength and the broadening of the diode laser's tunable range are discussed in detail. A feasible laser-induced fluorescence diagnosis technology scheme suitable for the divertor area of a future fusion reactor to measure the velocity distribution of helium neutral particles and detect helium ash elimination is promoted.

Key words: Helium ash removal, Velocity distribution of helium neutral particles, Laser induced fluorescence, Wavelength calibration

摘要： 利用多偶极腔体模拟聚变堆偏滤器附近氦中性粒子存在环境，通过激光诱导荧光诊断对于氦中性粒子的速度分布谱进行了直接测量，对测量区域的波长标定以及二极管激光器的可调谐范围的拓宽进行了研究。对该方案在聚变堆上的应用进行了评估。
