With the unprecedented range of ion species and energies offered by the newly commissioned CRYRING facility, the availability of single ion detectors is of significant importance as part of standard instrumentation as well as for novel experiments. A detector system was constructed on the basis of the YAP:Ce crystal scintillator, which is at once radiation‐hard, fast, and affordable. Results of a characterization experiment confirmed the feasibility of the setup for incident ion rates on the order of MHz and found a critical fluence of some 10¹³ cm⁻² upon which the crystal is rendered locally blind to further ion irradiation. The device was first used in CRYRING commissioning runs in August and November 2018. Future efforts will complete the integration of the detector into the GSI control and data acquisition system MBS.

基于闪烁体的粒子探测器，用于CRYRING @ ESR

由于新投入使用的CRYRING设施提供了前所未有的离子种类和能量范围，因此单个离子检测器的可用性对于标准仪器以及新颖的实验都至关重要。在YAP：Ce晶体闪烁器的基础上构建了一个探测器系统，该探测器系统辐射强度高，速度快且价格适中。表征实验的结果证实了设置兆赫量级入射离子速率的可行性，发现临界通量约为10 ¹³ cm ^-2在此之后，晶体对进一步的离子辐照变得局部不可见。该设备于2018年8月和11月首次在CRYRING试运行中使用。未来的努力将使检测器完全集成到GSI控制和数据采集系统MBS中。
