A 2 MV, multichannel, oil-dielectric, triggered spark gap
Abstract
A 2 MV, low jitter, multichannel, oil-dielectric spark gap was developed to be used for switching the transmission lines of proposed new relativistics electron beam (REB) accelerators with substantially increased peak power. The switch is designed for operation in a strip-line geometry with three 122 cm long electrodes, two smooth bars, and one sharp-edged trigger blade. When a voltage pulse that rises to 1.5 MV in 20 nsec is applied to the trigger electrode, about 10 arcs will close simultaneously in 30 nsec with a standard deviation less than 2 nsec. The spark gap was installed on one of two 22 omega 20 nsec strip transmission lines connected as a Blumlein test. The Blumlein output voltage pulse risetime decreases with increasing number of switch channels (13 nsec with 2 channels to 5 nsec for 14 channels). The effects of the interelectrode capacitance and isolation resistance on the operation of the switch are discussed. Design data for a prototype REB accelerator using twelve of these switches in parallel are presented.
