基于闪烁体的快离子损失探针的设计研究

摘要

The Scintillator based lost fast ion probe system is a detector which is used to measure the flux of es caping fast ions versus pitch angle and energy with time running in Tokamak devices. It is an important tool to study the transport and confinement of energetic ions. It studied the size of the scintillator screen,the proper scintillator material, and the collimation system of the lost fast ion probe to be used in HL -2A. The scintillator materials used for ITER is also studied.%基于闪烁体的快离子损失探针是用于测量托克马克装置中损失快离子的重要诊断设备.它能对损失快离子的能量和俯仰角进行同时测定,得到损失快离子通量随时间演化的信息,对研究快离子的约束输运行为有重要意义.针对HL - 2A对损失快离子诊断的具体需求,对用于HL - 2A的快离子损失探针的闪烁体屏尺寸、闪烁材料种类以及准直系统做了研究设计.同时对适用于ITER的闪烁材料种类进行了分析讨论.
