An electron beam controlled opening switch with a conduction period of ∼1 μs has been used in an inductive store system to generate a 280-kV, 60-ns full width at half-maximum voltage pulse across an open circuit by interrupting a 10-kA discharge. The switch was pressurized to 5 atm with a 99:1 mixture of CH4:C2F6. Degraded voltage performance was obtained with pure CH4 or N2. These results support the conjecture that a judicious choice of gas mixture can lead to optimization of such an opening switch in a parameter regime of interest to pulsed power applications.

    The trigger to generate high-voltage pulse is one of the most important parts in a pulsed-power system, especially for the conduction characteristics of the main switch. However, traditional triggers usually have the drawbacks of large structure and worse long-term working stability, which goes...

    Because a direct measurement of the voltage (V) in pulsed power bremsstrahlung sources can be difficult, the energy spectrum of x rays emitted is sometimes used to infer V. Both the voltage and current in such sources vary with time. Moreover, for modern x-ray simulators with multiple cathodes,...
