Description
Summary:The vertical test stand (VTS) plays a crucial role in evaluating the performance of superconducting radio-frequency (SRF) cavities. The VTS at the Platform of Advanced Photon Source Technology R&D (PAPS) has been developed by the Institute of High Energy Physics, Chinese Academy of Sciences (IHEP). In this paper, the digitalization (based on Field Programmable Gate Array, FPGA) and integration functionalities of VTS was carried out, which simplified the vertical test and improved efficiency greatly. Several vertical tests have been conducted at this upgraded VTS successfully, which adopted digital self-excited loop (SEL) and Experimental Physics and Industrial Control System (EPICS).
