摘　　要：介绍了安装在HT-7托卡马克装置上的电子回旋辐射外差诊断系统的原理;设计了一套测量系统,测量了石英玻璃和TPX材料在微波波段的插入损耗,为系统设计提供了必要的数据;研究了等离子体物理实验过程中在石英玻璃上沉积的膜的微波传输特性;测量了诊断系统的天线方向角,并分析了天线方向角给电子温度测量带来的影响。A set of heterodyne electron cyclotron emission radiometer has been employed on HT-7 tokamak to obtain plasma temperature. A compact System has been designed to measure the insertion loss of quantz glass and TPX in microwave band. The data of the insertion loss of these two materials is of importance for designing of microwave diagnostics in plasma devices. The influence of the deposition on quartz glass during plasma experiment is investigated. The antenna pattern of this radiometer has been measured and the resulting effect on electron temperature measurement has been analyzed.
