초록

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.
