Transmission efficiency of the ECRH system on HL-2A tokamak

Abstract

Abstract: The method for measuring the transmission efficiency of the HL-2A ECRH system is presented. The efficiency is about 90% by measuring the microwave power absorbed calorimetrically in the MOU, gyrotron output window and torus window of the EC system. A method of measuring power through parts of the transmission line besides MOU is provided.

Key words: ECRH, Power monitoring, Transmission efficiency

摘要： 介绍了HL-2A装置ECRH系统传输效率的测量方法。通过对MOU、回旋管输出窗口及真空密封窗口吸收功率的测量，得到HL-2A电子回旋系统的传输效率为90％左右。提出了除由MOU处测量微波功率外，可以由传输线的其他部位确定功率的方法。
