Study on the loss of neutral beam injected fast ions in EAST

Abstract

Abstract:

By means of classical guiding center orbit code ORBIT and combining with equilibrium code EFIT, as well as transport code TRANSP, the loss of neutral beam injected fast ions in EAST is calculated. 29% and 31% of the injected neutral beam ions were lost, with the beam power and energy given by 4MW (80keV) and 2MW (50keV), respectively, and the lost fast ions are strongly localized.

Key words: Neutral beam injection, Loss of fast ions, Guiding center code

摘要：

利用经典导心轨道程序ORBIT，结合平衡程序EFIT和输运程序TRANSP，计算了EAST中性束注入后快离子的损失情况。结果表明，4MW(80keV)氘离子的损失份额为29%，2MW(50keV)氘离子的损失份额为31%，损失的快离子有很强的局域性。
