The Super-KEKB[1] personnel protection system (PPS) takes care of not only Super-KEKB accelerator, but also Photon Factory - Advanced Ring (PF-AR), Positron Damping Ring (PDR)[2] and their beam transport lines (BT)[3]. The logic of the PPS has been changed to adapt the new accelerator operation scheme. The Experimental Physics and Industrial Control System (EPICS) was introduced into the PPS. Many tools developed under EPICS environment are used.

“…Interlock signals, block signals, and the reset signal are the input to the FPGA chip while LED signals and the control signal for the rf switch are the output. A Linux operating system is running on the FPGA chip with a cross-compiled EPICS IOC to monitor the interlock status [23]. A reset operation can be carried out remotely.…”

A new radio frequency (rf) conditioning system for power couplers has been developed for the High Energy Photon Source (HEPS) project. The system adopted a function-driven modular design, and the control software development was based on Experimental Physics and Industrial Control System (EPICS) platform to be compatible with the HEPS control system. Dedicated data acquisition system and in-house developed interlock system, as well as universal instruments and devices, constitute the main hardware infrastructure, while distributed EPICS input/output controllers, tailor-made operator interfaces, and data archiving comprise the control software pillars. Automatic control logics were developed to adjust the conditioning parameters according to vacuum pressure readings, thus largely spares human misoperations and considerably reduces the operator’s workload. Limited human supervision is required and the conditioning efficiency may be improved. Besides, data analysis and automatic report generation programs were developed and integrated into the conditioning system. Performances and behaviors of the couplers being conditioned can be easily obtained to help identify potential issues. The system has been used in the conditioning of power couplers and has also been customized to accommodate high-power tests of several other rf components thanks to its modular nature. The performance of both the hardware and the control software was excellent during the tests. The design, realization, and operation of the new rf conditioning system are presented.
