On Optical Properties Of Ion Beams Extracted From Electron Cyclotron Resonance Ion Source (1706.07583v1)
Published 23 Jun 2017 in physics.acc-ph
Abstract: 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.
