Abstract : The Gamble 1 pulsed electron beam generator at NRL recently has undergone several major modifications. The modified generator has a nominal output into a matched 1.5 ohm load of 500 kA at 750 keV, with a 70 nsec (FWHM) pulse length and a 20 nsec (10 to 90%) voltage risetime. The distinguishing characteristics of low prepulse (< 1%) and high reproducibility in output voltage and current (plus or minus 3%) result primarily from conversion from operation with self breakdown water switches to operation with triggered high pressure gas switches. Fast pulse risetime was maintained by using a low inductance multichannel triggered output switch in conjunction with a new low inductance vacuum diode with a radial insulator. (Author)
