摘要：
A high intensity proton RFQ accelerator for injector II of China ADS project was developed at Institute of Modern Physics, Chinese Academy of Sciences. Compared with RF power source for conventional accelerator, the control accuracy of power source for RFQ is much higher and the control processing is more complicate. Frequency tuning was achieved by water temperature control in the control system and the control accuracy can reach 0.1°C. Besides, to avoid the RFQ cavity from thermal damage, it is necessary to complete temperature monitoring and interlock protection at any time. For these reasons, the RFQ control system was designed based on EPICS framework. High performance redundant controller was used in operation platform with key control code. IOC drivers with network redundancy were developed, and the control of interlock protection and RF system were realized. Through the test on the spot, the control system can communicate successfully and operate stably. For the redundant system, the switching time is in the order of millisecond, which satisfies the requirement of RFQ cavity control.
