We report here that the unique geometry of the rotating dielectric spark ga
p allows the diode-less operation of a command resonant charging pulser net
work. An average power of about 3.5 kW with a peak value of 75 MW was switc
hed at a repetition rate of 600 Hz into a dummy load resembling a typical T
EA CO2 laser. (C) 2001 American Institute of Physics.
