摘要
根据EAST-NBI偏转系统工作原理,分析了束流在偏转系统传输的基本过程和特点。利用直接蒙特卡罗方法,发展了中性束注入器束偏转区域束流传输模拟程序。结果显示:EAST-NBI磁偏转系统可很好地剥离束流中的剩余离子;束偏转区域束流再电离损失约为2.43%;束流180°偏转所带来线聚焦过程使偏转磁体磁极护板局部面临较高的热流密度。
According to the working principle of EAST-NBI deflection system,the basic transmission process of the beam and characteristics of the deflection system were analyzed.Using Monte Carlo method,computer programs were developed to simulate the transmission of the neutral beam in the deflecting region.The results show EAST-NBI magnetic deflection system can strip the residual ions out of the beam passage;The loss of reionization in the beam deflection region is about 2.43%;Because of line focusing process caused by the 180 degrees deflection of the beam,the pole shields of the deflection magnet have high heat flux density.
