HL-1M装置的八发弹丸注入系统及工程实验

EIGHT-SHOT PELLET INJECTION SYSTEM FOR HL-1M AND ITS ENGINEERING EXPERIMENT

摘要: 八发弹丸注入系统自1996年投入HL-1M(中国环流器新一号)托卡马克加料实验并成功实现H₂弹丸的八发连续注入等离子体。描述了此系统及其在液氮和液氦条件下分别以CH₄和H₂为丸料气的工程实验。压力高于5MPa的He为推进剂,弹丸速度达800-1000m/s。

Abstract: Einght-shot pellet injection system has been experimented on HL-1M Tokamak for fueling in 1996 and eight H₂ pellets have been injected successively into plasma. This paper descriibes this system andit’s engineering experiments with liquid H₂ and liquid He, CH₄ and H₂ as pellet fuel gas respectively. Helium as propellant gas with pressure over 5MPa, the pellet velocity up to 800~1000m/s has been obtained
