间断磁探针阵列诊断数据的振荡模式分析

ANALYSIS OF THE MAGNETO-OSCILLATION MODE DATA GIVEN BY A DISCONTINUOUS MAGNETIC PROBE ARRAY

托卡马克磁探针阵列通常是围绕等离子体均匀布置的完整环形系统。由于受到布置空间的限制,HL 2A装置的磁探针只能组成带空白区域的间断阵列。在分析了HL 1M极向磁场振荡———Mirnov振荡模式的基础上,探索了HL 2A磁探针阵列诊断应注意的问题。

A magnetic probe array for diagnosing magnetooscillation modes on tokamaks is usually a toroidal system of magnetic probes aligned and evenly spaced around the torus. Due to the space limit, probes of the HL2A tokamak can only compose a nonuniform array with discontinuous gaps. Some problems with the oscillation mode diagnostics on the HL2A tokamak have been explored by analyzing oscillation modes on the HL1M tokamak.
