摘要
Resonant cavity Schottky detectors are powerful beam diagnostic devices which have been widely used in heavy-ion storage ring facilities worldwide. Aiming for a high signal-to-noise ratio and superior time resolution, a new cylindrical Schottky cavity detector with copper coating on the inner surface was developed and deployed in the HIAF-SRing Spectrometer Ring. The ultimate goal of the novel detector is to detect a single particle with a high signal-to-noise ratio (SNR). The detector operates at a nominal resonance frequency of 308 MHz (2.75 MHz tunable) and achieves a loaded Q-factor of ≈ 10, 000, ranking it as the top performer for heavy- ion detection among similar devices globally. The design considerations, simulation results, and measured performance of this cavity are presented in this work.
