摘要 闪烁快离子损失探针是聚变装置上诊断高能粒子的重要工具,可对损失离子能量和俯仰角进行同时测定.根据环流器二号(HL-2A)托卡马克装置上的具体测量要求,研制了一套可移动式的闪烁体快离子损失探针,并完成了在HL-2A上的安装和调试.该探针系统在有中性束加热的等离子体放电情形下实现了对损失快离子的探测,采集到了损失离子图像信息.根据已取得的初步实验结果,对HL-2A装置上的快离子损失探针系统的进一步完善进行了分析讨论. Scintillator-based fast ion loss detector （SFLID） is widely used as an important tool of energet-ic ions diagnosis on fusion device .SFILD can simultaneously measure the energy and pitch angle of esca-ping fast ions with the striking point on the scintillator plane .According to the measuring requirements of HL-2A tokamak device ,a movable SFILD has been designed and installed in HL-2A .The movable SFLID has been used to detect lost fast ions in plasma discharge with neutral beam injection （NBI）on HL-2A .Images of fast ion loss have been obtained by this movable SFILD .In addition ,the improve-ments of the design of detector head are also discussed .
