摘要：

在HL-2A装置的电子回旋辐射(ECE)外差测量中，为实现电子温度剖面分布的绝对测量，采用双温度法和磁场扫描法分别对扫频和多道ECE测量系统进行了标定，获得了各道间的相对标定系数，并利用等离子体中心道Thomson散射测量的电子温度对ECE测量系统进行了绝对标定。结果表明，这两种方法都能实现可靠的标定，并对两者的优劣进行了比较和讨论。

Abstract:

In the heterodyne measurement of electron cyclotron emission (ECE) on the HL-2A tokamak, in order to realize the absolute measurement of electron temperature profile, the two-temperature and the magnetic scanning methods are employed to relatively calibrate the frequency-scanning and the multi-channel ECE measurement systems respectively. The relative calibration coefficients between the channels are obtained. The absolute calibrations of ECE measurement systems are conducted by using the center electron temperature measured by Thomson scattering. The results show that both methods provide reliable calibration. The differences between the two methods are also compared and discussed.

Key words: Electron cyclotron emission, Heterodyne radiometer, Two-temperature calibration, Magnetic scanning calibration
