在HL-1M装置氢弹丸注入实验中,通过观测注入截面中的氢原子的H_α线发光强度对时间和空间的变化,在对几十发不同直径的弹丸注入方法进行分析的基础上,重点研究了氢弹丸的穿透特性、注入深度与弹丸速度之间的关系。 Spitzer于1954年就提出了采用弹丸注入方法对等离子体进行加料的设想,但时隔20年后,这种设想才引起人们的关注。由于弹丸注入加料效率高,且为控制等离子体密度提供了灵活性,而用中性气
Hydrogen projectile injection experiment HL-1M device, by observing the H_α emission intensity of hydrogen atoms in the injection cross-section changes in time and space, on the dozens of different projectile injection methods of different diameters on the basis of an analysis focused on The penetration characteristics of hydrogen projectiles, the relationship between injection depth and projectile velocity. Spitzer in 1954 put forward the idea of using the pellet injection method to feed the plasma, but after 20 years, this idea has aroused people’s attention. Due to the high feed efficiency of projectile injection and the flexibility to control plasma density, neutral gas
