V. Mironov, S. Bogomolov, A. Bondarchenko, A. Efremov, V. Loginov

摘要:

利用NAM-ECRIS程序得到的离子在引出孔径处的初始分布,模拟了DECRIS-PM源的离子引出。对等离子体发射面进行了三维计算,并对引出区的离子进行了示踪。的离子束轮廓显示出强烈的畸变,由于等离子体弯月面的形状,空心束的功能再现,以及在不同的聚焦条件下的轮廓的变化。

英文摘要:

Ion extraction from DECRIS-PM source is simulated by using initial distributions of ions at the extraction aperture obtained with NAM-ECRIS code. Three-dimensional calculations of plasma emissive surface are done and ions are traced in the extraction region. The ion beam profiles show strong aberrations due to shape of plasma meniscus; hollow beam features are reproduced, as well as changes in profiles for different focusing conditions.
