The Control System Design for 600kV High Voltage Platform of HIAF Electron Cooler

Published: 07 December 2021 Publication History

Abstract

HIAF is the next generation heavy ion accelerator in China, it contains lots of sub facilities. The electron cooler is one of the most significant facilities in HIAF of Spectrometer Ring (SRing). With the electron cooler, SRing could generate high quality and high intensity ion beam for the experiments. The electron cooler in HIAF was designed to produce 600KeV electron beam. To achieve this design target, high voltage needs to reach 600kV maximum and ripple wave less than 1*10-4. A new control system was designed for the high voltage platform which uses cascaded transformer construction. The system makes use of XGS-PON network as the main means of communication. Zynq 7015 as the CPU of the embedded controller. The controller integrated 2 DAC ports with 100KS/S and 4 ADC ports with 200KS/S for high voltage modules setting and high voltage divider monitor, 8 low-speed ADC ports for auxiliary power supplies, and the environment sensors. The embedded Ubuntu Linux and the EPICS frameworks were programmed in the controller, all of the control parameters were sent through channel access protocol. No need for host computer to participate in control logic, only used for display. The hardware mentioned above interacts with the operating system through the FPGA part of Zynq. The FPGA is programed as a coprocessor for communicating, data processing and interlock control. Corresponding drivers are integrated in the Linux system at the same time.
