以前的储存环CRYRING已经从斯德哥尔摩的Manne Siegbahn实验室运往达姆施塔特，作为瑞典对FAIR的实物捐赠。在ESR下游的新位置，目前ESR中可获得的所有离子都可以转移到CRYRING，其中可以存储刚性在1.44 - 0.054 Tm之间的离子。最初的瑞典式布局经过修改，重新配置了直线段的顺序，并将周长略微增加到ESR/2。离子可以从ESR或独立的300 keV/u RFQ测试注入器注入。环的仪器包括一个射频漂移管系统，用于加速和减速（1 T s−1，有可能升级到7 T s−1），电子冷却，自由实验部分，以及快速和慢速提取离子。我们报告了该项目的目前进展情况，给出了预期的时间表，并总结了该项目将使新的研究成为可能。储存环调试的第一束预计在2015年，2016年恢复超高真空条件的最终烘烤，并在2017年通过ESR注入离子束。
The former storage ring CRYRING has been shipped from the Manne Siegbahn Laboratory in Stockholm to Darmstadt as a Swedish in-kind contribution to FAIR. At its new location downstream of ESR all ion species presently accessible in ESR can be transferred to CRYRING, in which ions with rigidities between 1.44 and 0.054 Tm can be stored. The original Swedish layout has been modified by reconfiguring the sequence of straight sections and by slightly increasing the circumference to ESR/2. Ions can be injected from ESR or from an independent 300 keV/u RFQ test injector. The instrumentation of the ring includes an RF drift tube system for acceleration and deceleration (1 T s−1, with a possibility for an upgrade to 7 T s−1), electron cooling, a free experimental section, and both fast and slow extraction of ions. We report on the present progress of this project, give a prospective timeline, and summarize the new research which will be enabled by this project. First beam for commissioning of the storage ring is expected for 2015, final bakeout to restore ultrahigh vacuum conditions in 2016 and ion beams injected through ESR in ∼2017.
