The flash X-ray systems developed at the University of Texas at Dallas (UTD) centers on two critical subassemblies: (1) a Blumlein pulsed power source and (2) an X-ray diode properly designed and matched to the pulse forming line. The pulse generator

In this paper we review a novel microwave power sensor, the operation of which is based on the electron-heating effect in semiconductors. The sensor has been specifically developed for the measurement of high-power microwave pulses. The sensor's prin

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

The stacked Blumlein pulse generators developed at the University of Texas at Dallas consist of several triaxial Blumleins stacked in series at one end. The lines are charged in parallel and synchronously commutated with a single switching element at

The dielectric strength of highly purified insulating transformer oil has been measured in the sub-nanosecond regime under single pulse and repetitive burst conditions. Single pulse breakdown fields have been measured to be 11 MV/cm. Repetitive burst

In this letter, we report on the numerical investigation of resonances within waveguide type resistive sensors used for measuring high power microwave pulse radiation in the X-band. We have applied a finite-difference time-domain method to determine

Silicon diodes operated in an avalanche breakdown mode can he used to reduce, or sharpen, the rise times of driving pulses. Proper operation of a diode in this manner requires the application of a driving pulse with sufficient time rate of change of

In the basic research efforts to define the optimum isomers for making a gamma-ray laser, a variety of radiation sources have been used to find the nuclear gateways that make the idea possible. The radiation sources have several roles to play in the
