Pulsed electrostatic kickers with low beam impedance for AmPS
Abstract
The characteristics of the pulsed electrostatic kickers for the Amsterdam Pulse Stretcher (AmPS) are presented. During 3 turns injection into AmPS, two identical electrostatic kickers create a local vertical displacement of the closed orbit of the ring by a 2.75 mrad bend. Within 10 microseconds, the 1570 mm long parallel plates of the kickers are charged to + and - 35 kV by a triode switch. The fast discharge of the plates, required at the end of the injection cycle of 2.1 microseconds, is achieved by using very fast thyratrons. A discharge time of less than 100 ns is shown in bench tests. The synchronous discharge of the two kickers requires a timing error of less than 1 ns. Timing jitter is reduced by the improved stability of the thyratron adjustments. The measured longitudinal broadband impedance (Z/n) of the kicker is (0.21 +/- 0.05) omega.
