为测量HL-2A装置上的电子温度分布，设计了一台新型的32道电子回旋发射辐射计并进行了测试。该系统基于中频滤波检测技术，具有工作频率范围宽、空间分辨率高等特点。研究了两种相对定标方法：扫描环形磁场和跳频本振输出频率。初步结果表明，两种方法都能保证合理的剖面。
A novel 32-channel electron cyclotron emission radiometer has been designed and tested for the measurement of electron temperature profiles on the HL-2A tokamak. This system is based on the intermediate frequency filter detection technique, and has the features of wide working frequency range and high spatial resolution. Two relative calibration methods have been investigated: sweeping the toroidal magnetic field and hopping the output frequency of the local oscillator. Preliminary results show that both methods can ensure reasonable profiles.
