高频冰冻弹丸制备系统的研制及其工程调试

Development of High-frequency Cryogenic Pellet Preparation System and its Engineering Commissioning

与俄罗斯培林实验室联合研制的60Hz高频冰冻弹丸制备系统已研制完成:能制备直径Φ1.0mm、长度L1.0mm~1.3mm可调节的圆柱形冰冻弹丸;最高注入频率60Hz;注入速度100m/s~300m/s。工程调试结果表明,弹丸制备系统能稳定可靠地运行,能较好地制备冰冻弹丸,为在HL-2A/2M装置上开展弹丸注入相关物理研究提供基础。

The 60 Hz high-frequency cryogenic pellet preparation system was successfully developed with the collaboration of PELIN Laboratory Ltd.It was designed to produce cylindrical cryogenic pellets with diameter of 1.0 mm and adjustable length of1.0 mm~1.3 mm.The pellets can be injected into the plasma at a frequency within 60 Hz with an adjustable speed at 100 m/s~300 m/s.The engineering commissioning shows that the preparation system meets the design requirements of preparing pellets,and can run stably and reliably.It provides a basis for the physical research of pellet injection on the HL-2 A/2 M tokamak.
