Title: EM computer model of the time dependent ATA injector voltage

Abstract

An acceptable beam initial condition is most easily generated for propagation experiments when the beam energy variation is as flat as possible. Small energy variation helps to suppress instabilities and minimize transport problems. The ATA injector determines the beginning beam energy variation from the stalk resistance and specification of the time dependence of the applied voltage. The injector emits a beam from a diode configured with two re-entrant stalks, driven by 10 gaps. Ideally the gaps are triggered with a time of flight delay. In order to study the injector behavior when ideal gap triggering is not realized or stalk resistance is varied, an electromagnetic PIC computer model has been used. 5 figs.
