| 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 tempera... |
