摘要：
我们报告了将SPARC（存储粒子原子物理学研究合作组织）开发的新型磁性微量热计探测器（MMC）首次集成到达姆施塔特GSI的存储环实验环境中，即CRYRING@ESR的电子冷却器中。两个这样的探测器系统被放置在0 $^\circ$和180 $^\circ$观察口的冷却器部分，以获得高分辨率的X射线光谱源于存储的类氢铀束与冷却器电子相互作用。虽然以前的测试测量与微量热仪在加速器设施的GSI进行了完善的独立操作的模式，对于本实验中，我们实施了几个显着的修改，以充分利用这种类型的检测器的潜力，精确的X射线光谱存储的重离子。其中包括与GSI的多分支系统数据采集平台兼容的新的读出系统，准连续能量校准与加速器设施的操作周期的同步，以及首次利用maXs探测器的时间分辨率来应用光子和电荷变化离子探测的符合条件。
英文摘要：
We report on the first integration of novel magnetic microcalorimeter detectors (MMCs), developed within SPARC (Stored Particles Atomic Physics Research Collaboration), into the experimental environment of storage rings at GSI, Darmstadt, namely at the electron cooler of CRYRING@ESR. Two of these detector systems were positioned at the 0$^\circ$ and 180$^\circ$ view ports of the cooler section to obtain high-resolution x-ray spectra originating from a stored beam of hydrogen-like uranium interacting with the cooler electrons. While previous test measurements with microcalorimeters at the accelerator facility of GSI were conducted in the mode of well-established stand-alone operation, for the present experiment we implemented several notable modifications to exploit the full potential of this type of detector for precision x-ray spectroscopy of stored heavy ions. Among these are a new readout system compatible with the multi branch system data acquisition platform of GSI, the synchronization of a quasi-continuous energy calibration with the operation cycle of the accelerator facility, as well as the first exploitation of the maXs detectors' time resolution to apply coincidence conditions for the detection of photons and charge-changed ions.
