描述了一种基于电子束产生等离子体的新型离子源。它具有效率高、工作温度高(∼3000K)的特点。它不包含磁场，并提供适合质谱分析的高质量束流。不需要支持气体PER。研究了源的等离子体理论原理，计算了电离效率、延迟时间、载流子密度、压强、电流密度等参数。将这些计算与实验和计算机模拟进行了比较。
A novel ion source based on an electron-beam-generated plasma is described. It features high efficiency and high temperature operation (∼ 3000 K). It does not incorporate magnetic fields and delivers beam of high quality suitable for mass spectrometry. No support gas per is required. The plasma theoretical principle of the source is investigated and ionization efficiencies, delay times, charge carrier densities, pressure limits, current densities etc. are calculated. These calculations are compared with experiments and computer simulations.
