Abstract:

Photoconductive switching of the Stacked Blumlein pulsers, developed at the University of Texas at Dallas, currently produces high power, nanosecond pulses with risetimes on the order of 200 ps. The device has a compact geometry and is commutated by a single GaAs switch triggered by a low power laser diode array. This report presents the progress toward improving the high gain switch operation and lifetime in stacked Blumlein pulsers. Feasibility of the use of amorphic diamond to enhance the switch operation and longevity is discussed Improvement in switch lifetime was demonstrated by coating the triggered face of a GaAs switch cathode with highly adhesive film of amorphic diamond.
