为满足大型螺旋装置堆芯直接加料的需要,研制了一台20管固体氢弹丸注入器,该注入器能以1200 m/s的速度注入20个直径和长度在3.0 ~ 3.8 mm之间的圆柱形弹丸。在原位管枪的概念与紧凑的低温冷却器的使用,使稳定的操作作为一个基本的设施,在等离子体实验。两种颗粒喷射定时控制模式的组合,即,预编程模式和实时控制模式,允许在密度极限附近建立和维持高密度等离子体。在过去三年的铲运机试验中,弹丸喷射器表现出稳定的工作特性。
A 20 barrel solid hydrogen pellet injector, which is able to inject 20 cylindrical pellets with a diameter and length of between 3.0 and 3.8 mm at the velocity of 1200 m/s, has been developed for the purpose of direct core fueling in LHD (Large Helical Device). The in situ pipe gun concept with the use of compact cryo-coolers enables stable operation as a fundamental facility in plasma experiments. The combination of the two types of pellet injection timing control modes, i.e., pre-programing mode and real-time control mode, allows the build-up and sustainment of high density plasma around the density limit. The pellet injector has demonstrated stable operation characteristics during the past three years of LHD experiments.
