为了向海德堡重离子储存环TSR注入高强度的单电荷重离子，研制了一套由两个双腔和8个射频七隙腔组成的高频加速器系统HSI。使用不同的离子源，该系统现在用于提供能量在150 keV/a.m.u.之间的正或负原子和分子离子束。和5.3 MeV/a.m.u.对于MP串联后加速器系统的未来替换，新的HSI加速器将配备用于高强度高电荷离子的ECR源。一个先进的商业ECR源与18 GHz射频速调管和可调提取系统的适应范围广泛的注入能量已委托制造商和交付。目前，海德堡正在准备测试台的运行。在注入器和后加速器之间正在建造一个带有消色差电荷状态选择器的汽提段。其它离子源，例如，用于超冷H3+分子离子束的技术正在开发中。
A specialized rf-accelerator system HSI consisting of two RFQ’s and 8 rf seven-gap cavities was built for injection of high intensities of singly charged heavy ions into the Heidelberg heavy ion storage ring TSR. With different ion sources, this system now is used to deliver positive or negative, atomic and molecular ion beams with energies between 150 keV/a.m.u. and 5.3 MeV/a.m.u. final energy.For a future replacement of the MP-tandem-postaccelerator-system the new HSI-accelerator is to be equipped with an ECR source for high intensities of highly charged ions. An advanced commercial ECR source with a 18 GHz rf klystron and an adjustable extraction system for adaption of a wide range of injection energies has been commissioned at the manufacturer and is delivered. Test bench operation presently is in preparation at Heidelberg. A stripper section with an achromatic charge state selector is under construction between injector and postaccelerator. Other ion sources, e.g., for ultra cold H3+ molecular ion beams are under development.
