Abstract :
Summary form only given. The Pulserad electron beam accelerator at the University of New Mexico (UNM) was refurbished and reconfigured to provide a voltage pulse with a very fast risetime, inspired by simulation results that indicated that the magnetron output characteristic was very sensitive to the voltage risetime. The modified Pulserad has a 2 ns risetime after which it maintains a flat-top for 30 ns and is capable of providing 350 kV into a matched load of 20 Ω. The main contributing factor for such a fast risetime is the low inductance oil breakdown switch located between the pulse forming line and the transmission line. Additionally, a low inductance transition region between oil and vacuum was designed to keep the degradation to the risetime minimal.
