论文摘要
我们报告了在SPARC（存储的颗粒原子物理学研究协作）中开发的新型磁性微氧计探测器（MMC）的首次整合到GSI，DARMSTADT的储存环的实验环境中，即在Cryring@ESR的电子冷却器上。这些检测器系统中的两个位于0 $^\ Circ $和180 $^\ Circ $查看较冷段的端口，以获得高分辨率的X射线光谱，该光谱源自与冷却器电子相互作用的氢样铀的存储光束。虽然在GSI的加速器设施处使用微钙化器的先前测试测量是以完善的独立操作的方式进行的，对于本实验，我们实施了几种显着的修改，以利用这种类型的检测器的全部潜力，以实现储存重型离子的Precision X射线光谱。其中包括与GSI多分支系统数据采集平台兼容的新读数系统，即准加速器设施的运行周期，将准连续的能量校准同步，以及首次利用Maxs探测器的时间分辨率，以将光量的巧合用于检测光子和电荷的巧合。
We report on the first integration of novel magnetic microcalorimeter detectors (MMCs), developed within SPARC (Stored Particles Atomic Physics Research Collaboration), into the experimental environment of storage rings at GSI, Darmstadt, namely at the electron cooler of CRYRING@ESR. Two of these detector systems were positioned at the 0$^\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.
