| Abstract: | The 2mm-band microwave scanning heterodyne radiometer (MSR) in the HL-1M tokamak was upgraded by changing the BWO and upgrading the high voltage power supply and control system.Meanwhile,the IF amplifier of MSR with high gain,broadband and low noise has been developed.The methods for calibration of new BWO frequency,frequency response and sensitivity of the detector are described in this paper.The results of calibration and adjustment of the MSR system are presented.The design circuit of the IF amplifier for this receiver and its measurement results are also presented. |
