| Abstract: | A new kind of pulse electron gun controller for 200 MeV LINAC at National Synchrotron Radiation Laboratory was introduced in this paper, including the working principle of the pulse electron gun, the applications of I~2C serial bus and embedded microcontroller in controlling system. The emphasis is on the hardware design of digital controlled current regulator, digital controlled switch voltage source and high voltage pulse power supply. The software design of fiber communication and PC controlling is also presented. The electron gun controller has successfully been used in NSRL. The result shows that it is quite reliable and the performance is good. This electronic digital system has completely replaced the old mechanical control system. |
