EAST上离子回旋加热系统现状

Current Status of ICRF Heating Experiments on EAST

摘要: 离子回旋加热是EAST上主要的辅助加热技术之一。目前, 离子回旋系统设计的总功率为6MW, 未来, 离子回旋系统提供的总的加热功率将达到10MW。在2010年EAST实验中, 已经投入3套1.5MW的加热系统, 频率范围在25-70MHz。在EAST上我们设计了二套离子回旋天线, 每套天线沿环向有二根电流带, 每个电流带由一台1.5MW的发射机提供功率。本来将介绍离子回旋系统的能力, 特别是在2010年的实验中获得一些结果。

Abstract: Radio frequency (RF) heating in the ion cyclotron range of frequencies (ICRF) is one of the primary auxiliary heating methods for EAST. The ICRF system provides 6 MW power in primary phase and will be capable of 10 MW later. Three 1.5 MW ICRF systems in a frequency range of 25 to 70 MHz have already been in operation. The ICRF heating launchers are designed to have two current straps with each driven by a RF power source of 1.5 MW. In this paper a brief introduction of the ICRF heating system capability in EAST and the preliminary results in EAST are presented.
