The PET cyclotron can provide 10 MeV proton beams, the beam intensity for 50 eμA . H− ion beams are accelerated to 10 MeV energy and then the proton beams are obtained by stripping. The control system includes several subsystems: data acquisition system, data processing system, data archiving system and machine protection system. On the hardware, the standard plugins of control modules, PLC and FPGA integrated circuits were used in data acquisition system. On the software, design patterns and modular design methods were applied. The control software based on the distributed control system structure was developed with Visual C++. The stability during beam commissioning verified reliability of the proposed control system. With the help of the control system, the ion source has successfully extracted the H− ion beams with expectations of a dc of 1.5 mA @ 25 KeV extraction energy and 2000 W arc power.

“…The devices placed on the platform are always operating in an extremely harsh environment, in which they can be exposed to maximal voltages of 60 kV. In addition, all of the devices and controllers operate under strong electromagnetic fields, radioactive radiation and high voltage surroundings [4] . These conditions may damage the controllers.…”

“…Moreover, inject vacuum, extract vacuum and beam vacuum are interlocked with High Voltage Power Supply and Microwave Machine too. The interlock protection and alarm is implemented by a self-developed module known as the VAC600 [4] . The sources used to trigger the interlock and protection alarm is implemented by "or" logic.…”

To improve the control efficiency of Superconducting Electron Cyclotron Resonance Ion source(SECRAL) for Heavy Ion Research Facility in Lanzhou(HIRFL), a upgrade version of control system for SECRAL is designed and set up. The control software package is developed by Visual C++, which is able to control and monitor all of the equipment for the SECRAL system about 130 parameters. The previous analog power supplies are replaced by four digital power units at High Voltage(HV) platform, The old slow speed of AC motors are upgraded to servo motors newly for higher precision, stability and linearity. Meanwhile, some control strategy and user interface are optimized. In order to prevent the incorrect operation which may cause the quench of the superconducting magnet, alarm and interlock protection functions are added to the software and hardware.Since the upgraded SECRAL control system is online, it has been running smoothly.
