Vacuum arc ion sources, Penning ion sources, and filament driven multicusp ion sources are used for the production of high current ion beams of a variety of metallic and gaseous ions at the GSI accelerator facility. For accelerator operation, the ion sources have to provide a stable beam over a long period of time with an energy of 2.2 keV/u and a maximum mass over charge ratio of 65. The status of beam time operation at the high current injector is presented here giving an outline on important ion source data, such as ion beam current, ion beam spectrum, transversal emittance, life time, duty factor, and transmission along the low energy beam transport section.
在德国重离子研究中心（GSI）加速器设施中，真空电弧离子源、潘宁离子源和灯丝驱动的多尖离子源用于产生各种金属和气体离子的高电流离子束。对于加速器运行，离子源必须在很长一段时间内提供能量为2.2 keV/u、最大质荷比为65的稳定束流。本文介绍了高电流注入器的束流时间运行状态，概述了重要的离子源数据，如离子束电流、离子束光谱、横向发射度、寿命、占空比以及沿低能束流传输段的传输情况。
