摘要

电子回旋共振离子源(ECRIS)操作的重要特征用数字代码精确再现。该代码使用细胞内粒子技术来模拟ECRIS等离子体中离子的动力学。结果表明，气体动力离子约束机制足以使ECRIS的离子生成速率接近实验观测值。对提取的离子电流进行了计算，并与实验进行了比较。随着进入源腔的气体流量和微波功率的变化，提取的离子流发生了变化。研究了ECRIS设计的经验标度规律，并讨论了潜在的物理效应。

Numerical model of Electron Cyclotron Resonance Ion Source

Important features of Electron Cyclotron Resonance Ion Source (ECRIS) operation are accurately reproduced with a numerical code. The code uses the particle-in-cell technique to model a dynamics of ions in ECRIS plasma. It is shown that gas dynamical ion confinement mechanism is sufficient to provide the ion production rates in ECRIS close to the experimentally observed values. Extracted ion currents are calculated and compared to the experiment for few sources. Changes in the extracted ion currents are obtained with varying the gas flow into the source chamber and the microwave power. Empirical scaling laws for ECRIS design are studied and the underlying physical effects are discussed.

期刊介绍： Physical Review Special Topics - Accelerators and Beams (PRST-AB), is a peer reviewed, purely electronic journal, distributed without charge to readers and funded by contributions from national laboratories. It covers the full range of accelerator science and technology: subsystem and component technologies, beam dynamics; accelerator applications; and design, operation, and improvement of accelerators used in science and industry. This includes accelerators for high-energy and nuclear physics, synchrotron radiation production, spallation neutron sources, medical therapy, and intense beam applications.
