Abstract

An electron gun system for the Pohang Light Source has been installed and operated successfully. The basic design parameters are acceleration voltage of 80 kV, maximum peak emission current of 5 A, minimum pulse width of 1 ns, and maximum repetition rate of 100 Hz. The gun has a triode structure and is composed of a cathode, a focusing electrode(Wehnelt), and an anode. To sustain a $5{\times}10^{-9}$Torr vacuum, a $230{\ell}/s$ Ion pump has been adopted. We adopted a control and monitoring system based on the fiber-optic technology. In this article, we present the structure and operation principle of the system with special interest on the nanosecond pulser, remote control and monitoring system.
