HL-2A装置2MW电子回旋共振加热系统研制

Development of 2MW ECRH system on the HL-2A tokamak

HL-2A装置电子回旋共振加热系统的主要指标是2MW/1s/68GHz,系统由4个单元组成,每个单元包括一只回旋管,微波传输系统,控制保护测量和冷却等子系统。通过对ECRH系统和回旋管的调试,每只管子微波输出功率500kW,脉冲宽度1s,四管并联运行时总输出功率达到1.63MW,系统使用效率高于80%。

The main parameters of ECRH system in HL-2A tokamak are output power 2MW, pulse duration ls and frequency 68GHz. The system consists of four units, which are comprised of a gyrotron, a transmission line and control, protection, measurement and cooling subsystem each. After commissioning, the 500kW/ls output power has been obtained for every gyrotron and the total output power was up to 1.63MW for four gyrotrons parallel operation. The efficiency of the ECRH system is over 80%.
