An improved design of a longitudinally sensitive resonant Schottky cavity pickup for the heavy ion storage rings of the Facility for Antiproton and Ion Research in Europe (FAIR) project is reported. The new detector has a higher measured Q value of ∼3000 and a higher simulated shunt impedance of 473.3 kΩ. It is possible to vary the sensitivity of the cavity with a motorized mechanism by inserting a dissipative blade during the operation based on experimental needs. Apart from a lower price tag, the new design features a more robust and production-friendly mechanical structure suitable for a series production in the future FAIR project. The manufactured cavity was built temporarily into the experimental storage ring and had delivered its first results using stored heavy ion beams. The structure, simulation results, and performance of this cavity are presented in this work.

用于重离子存储环的 410 MHz 谐振腔拾音器

据报道，欧洲反质子和离子研究设施 (FAIR) 项目的重离子存储环纵向敏感谐振肖特基腔拾音器的改进设计。新检测器的测量 Q 值更高，约为 3000，模拟分流阻抗更高，为 473.3 kΩ。根据实验需要，在操作过程中插入消散刀片，可以通过电动机构改变腔体的灵敏度。除了较低的价格标签外，新设计还具有更坚固和生产友好的机械结构，适用于未来 FAIR 项目的批量生产。制造出的空腔临时内置在实验存储环中，并使用存储的重离子束提供了第一个结果。结构、仿真结果、
