地球物理研究所将安装减速机，以便提供和研究裸重核或只有很少电子、能量极低甚至静止的重核。在相对论能量下剥离会产生高电荷离子。电子在实验存储环中冷却和减速后，离子以4mev /u的速度从存储环中喷射出来，并以IH和RFQ结构的组合方式进一步减速。最后，它们被注入潘宁阱，在那里离子被冷却到4k。从这里，离子可以以准直流电或脉冲模式转移到不同的实验装置。本文介绍了该项目的技术概念和拟进行的重点实验。
A decelerator will be installed at GSI in order to provide and study bare heavy nuclei or heavy nuclei with only few electrons at very low energies or even at rest. Highly‐charged ions will be produced by stripping at relativistic energies. After electron cooling and deceleration in the Experimental Storage Ring the ions are ejected out of the storage ring at 4 MeV/u and further decelerated in a combination of an IH and RFQ structure. Finally, they are injected into a Penning trap where the ions are cooled to 4 K. From here, the ions can be transfered in a quasi dc or in a pulsed mode to different experimental setups. This article describes the technical concepts of this project as well as planned key experiments.
