摘要
为了在HT—6M托卡马克装置上开展低杂波驱动等离子体电流的实验研究,我们建立了一套颇有特色的低杂波射系统。该系统主要由微波源、传输系统和天线三部分组成。我们采用独特的磁场调制方法实现了连续波磁控管的脉冲运行,峰值输出功率为P=30kW,脉冲宽度τ<30mS。研制了一种新型的Grill——多结波导阵天线,使传输系统大为简化。该系统已成功地应用于低杂电流驱动实验,取得了予期的实验结果。
We have set up a Lower hpbrid wave RF System with some particular in order to perform lower hybrid current drive experiments in the HT-6M Tokamak. The System consists of three parts mainly:microwave Source.transmission line and antenna.Pulse operation of the magnetron source with Pmax=30kW andτ>30ms has been brought into being by means of magnetic field moduration.A new kind of Grill— multijunction waveguide array antenna has been developed,which simplifies the tran- smission system largely.Lower hybrid current drive experiments using this RF system have been carried out in HT—6M Tokamak successfully and obtsined ideal results.
