abstract = {Acceleration of electrons in plasma wakefields is one of
the prime candidates for complementing or partially
replacing conventional accelerator technology, due to its
superior acceleration gradients. The plasma acceleration
medium is often supplied independently of the acceleration
process by e.g. electrical discharging an external current
through a gas. Such discharge plasma sources are typically
operated at several 10’s of Hz but have also been operated
at up to kHz repetition rate. Here, we present the design of
a high voltage pulse modulator capable of supplying 10 kV,
400 A peak current pulses at 1 kHz repetition rate into
a dynamic plasma load. The pulse circuit is based on a
low-loss silicon carbide switch and passive
pulse-recirculation, which allows reduction of the power
consumption by up to $50\%$ and also monitoring of the
energy deposition in the plasma load.},
