A system which enables a closed line magnetic confinement device to be filled with a laser-produced hydrogen plasma has been constructed. The design and initial performance of this system using targets 0.25 mm in diameter is reported here. The device moves the laser focus to intercept an injected pellet within a specified target area. The system detects the path of the pellet after launching, electronically predicts its trajectory, and deflects mirrors to a position that will move the laser focus to intercept the pellet within the target area. Glass pellets were used to commission the system and all that passed through the detector area were successfully intercepted.
已构建了一种能使封闭磁力约束装置充满激光产生的氢等离子体的系统。本文报道了该系统使用直径为0.25毫米的靶材时的设计和初始性能。该装置移动激光焦点，以便在指定的靶区内拦截注入的小球。该系统在小球发射后检测其路径，通过电子方式预测其轨迹，并将反射镜偏转至一个位置，该位置会使激光焦点移动以在靶区内拦截小球。使用玻璃小球对该系统进行调试，所有通过探测器区域的小球均被成功拦截。
