Abstract

Abstract:

The engineering test of 1MW LHCD system has been carried out using one klystron. The LHCD system vacuum pumping had been set up for the transmission line and launch antenna. The vacuum in antenna and transmission are 2.3 Pa and 4.3×10² Pa respectively, and the leakage factor is 1.675×10^-4 Pa•m³•s^-1between antenna and tokamak. To improve capability of transmission power and avoid arcing in wave guide, gas is filled in the space between antenna and Tokamak. Vacuum characteristics of the LHCD system and its influence on the vacuum of HL-2A tokamak are studied preliminary.

Key words: LHCD, Vacuum

摘要：

HL-2A装置的1MW低杂波电流驱动系统在单只速调管的条件下进行了系统的工程调试。建立了低杂波真空系统，天线真空度为2.3 Pa，传输系统真空度为4.30×10² Pa，天线对装置的漏率为1.675×10^-4 Pa•m³•s^-1。采用低真空条件下充气的方法提高了系统的功率传输能力，有效地降低和避免了打火情况的发生，初步分析了低杂波系统的真空性能以及对HL-2A装置真空的影响。
