• A computational study has been made on the design of a 150-kV triodelike switchable electron gun. A smooth magnetic cusp arrangement was used to produce an axis-encircling beam. Numerical optimization of this arrangement led to a gun design that produced beam parameters of I_{b} \sim \hbox{6}\ \hbox{A} , \alpha = \hbox{1.2} , and d\alpha \sim \hbox{15}\% . It has also been shown that this triode design can produce beam suppression at \sim 2 kV while not interfering with the beam parameters under operation conditions.
