PLS-II 전자총 진공이원화와 빔 전류 인출시험
PLS-II separator the vacuum electron gun beam current emission test
초록
The linear accelerator of Pohang Accelerator Laboratory(PAL) will drive a top-up mode operation in PLS-II(Pohang Light Source-II). Due to this kind of the operation mode, the electron gun is expected to have shorter life time of the cathode. Further in the PLS-II, two gate valves will be installed in front of the electron gun. The distance between the pre-bunching section and the electron gun will increase by 400 mm compared to the existing system due to the insertion of these gate valves. As a result the incident electron beam. One of the goals to improve the beam pulse width is by incorporating suitable biased voltage. In this paper, we will present test results of beam pulse width as a function of different biased voltage and focusing solenoid coil.
