本文提出了一种制备示踪剂包封固体小球（TESPEL）的新方法，用于示踪剂离子在堆芯等离子体中的局部沉积和粒子输运的精确测量。该方法允许制造聚苯乙烯壳形式的TESPEL，其内部含有氢化锂作为示踪剂。TESPEL加速已经成功进行，飞行中的弹丸照片证实了TESPEL的完整性。对于直径为300-400 μm、壁厚为40-50 μm的颗粒，颗粒脆性变得不显著。TESPEL烧蚀率的计算表明，所获得的弹丸速度和尺寸适合于注入中等尺寸的等离子体。有人提出，为了更好地定位等离子体中沉积的示踪剂离子，对示踪剂含量进行分级。这些实验中获得的数据证明，注射由塑料壳制成的TESPEL可以是一种很有前途的粒子传输工具。
A new method for producing a tracer-encapsulated solid pellet (TESPEL) has been developed for a local deposition of the tracer ions in the core plasma and an accurate measurement of the particle transport. The method allows manufacturing of TESPELs in the form of polystyrene shells containing lithium hydride inside as a tracer. The TESPEL acceleration has been successfully performed and photos of the pellets in flight confirmed the TESPEL integrity. For the pellets with diameter 300–400 μm and wall thickness 40–50 μm the pellet fragility becomes insignificant. Calculation of the TESPEL ablation rate has showed that the achieved pellet velocities and sizes are appropriate for the injection into a medium size plasma. It was proposed to fractionate the tracer contents in order to provide better localization of the deposited tracer ions in the plasma. The data obtained in these experiments have proved that injection of the TESPEL made from the plastic shells can be a promising tool for the particle transport ...
