Abstract:

A low impedance high power pulsed electron beam accelerator utilizing a water dielectric coaxial pulse line has been developed. The electron pulse is initiated by the simultaneous triggering of four parallel, 2 MV, low inductance, gas insulated spark gap switches with a scatter of less than 2 ns. The electron beam pulse, produced in a 15 nH field emission diode, has a peak amplitude of 835 keV at 850 kA, a 1e current risetime of 20 ns and a duration of 80 ns. The 1.5 ohm pulse line is directly charged from a fast Marx generator and is matched through the switches into a transfer section connected to the diode. This section has sufficient shunt capacity to suppress the prepulse associated with the charging pulse. The beam power and total energy are in good agreement with the calculated output. Author
