The old kicker control system which has been operated over 5 years cannot satisfy the requirements of current special physics experiments. The main reason is the 5 ns time precision restricts the improvement of the precision for the phase detection of the beam bunches.展开更多

The control software package is developed by Visual C++, which is ableto control and monitor all of the equipment for the SECRAL system with about 130 parameters. The previousanalog powers are discarded and four digital high powers are used newly at high voltage platform, which containtwo stove powers, a bias voltage power, and a sputter power. Moreover, four servo motors are added newly, whichcontain work gas, support gas, bias voltage, and sputter voltage. Reflecting vacuum value picturesquely, we plot agraph of inject vacuum, elicit vacuum, and beam vacuum against time. In order to prevent the misoperation whichmay cause the quench of the superconducting magnet, alarm and interlock-protection functions are added to thesoftware and hardware. Simultaneously, added stretch buttons are able to void accidental on-click that might bringabout serious outcome.展开更多

Before the SFC-ES position monitoring system was build, the actual position of the cuttingpole and the high voltage cathode pole cannot be "seen" for beam tuning stuff. So they can only tuning the beam"blindly". This is very dangerous, in case of over adjusting the pole, serious damage may be caused. To avoid thiskind of damage, a route limit monitoring system was built in 2012. Using this system, the beam tuning stuff canget the information whether the cutting pole/the high voltage cathode pole is reaching the route limit. If the polehas reached the limit, there will be alarm information in the GUI interface to inform the beam tuning stuff to stopthe motor and change the moving direction. Although this can prevent big damage, precision position detectionfunction cannot be reached, and the SFC extraction electrostatic deflection plate still should be pulled out to checkthe position manually.展开更多
