建立了一种用于制造示踪剂包裹的低温小球的装置，以用于精确的输运诊断系统，以测量磁约束装置中平行和垂直于磁场线的粒子输运。对于示踪剂包覆小球的典型构型，建议将一个50-250μ的直径为50-250 mm的示踪剂，由锂、碳等轻原子封装在1-3 mm直径的圆柱形氢球的中心。为了演示装置的操作，将一个直径为240μ的碳球封装在一个直径为3 mm的圆柱形氢气球的中心，并在试验室中用轻气炮加速到400-800m/S的速度。从两个方向同时拍摄了小球，并将两个二维图像重建为三维图像。从而论证了该装置的工作原理。
A device for producing a tracer-encapsulated cryogenic pellet is constructed for an accurate transport diagnostic system to measure particle transport both parallel and perpendicular to the magnetic-field lines in magnetic confinement devices. As for the typical configuration of the tracer-encapsulated pellet, it is proposed that a 50–250 μm diam tracer made of a light atom such as lithium, carbon, etc., is encapsulated in the center of a 1–3 mm diam cylindrical pellet of hydrogen. For demonstration of the device operation, a 240 μm diam carbon sphere is encapsulated in the center of a 3 mm diam cylindrical pellet of hydrogen, and accelerated by a light gas gun to velocities of 400–800 m/s in a test chamber. The pellet has been photographed simultaneously from two directions and the two two-dimensional images are reconstructed to a three-dimensional image. Thus, the proof of principle of the device operation has been demonstrated.
