Abstract:

The Hybrid Radiation Source HRS is a compact pulsed power generator consisting of a commercial flash x-ray system that has been retrofit with a custom front-end assembly, replacing a sealed glass tube. The HRS diode hardware consists of a tapered tungsten anode extended through an annular stainless steel cathode. The HRS has been successfully fielded, however, some source parameters, such as voltage, current, and source size, were not known. These parameters as well as the dose have now been measured with an array of diagnostics. Also, a circuit model has been developed to enable optimization and analysis of the complete system. The source size has been dramatically reduced by using a 1-mm-OD tapered anode. Anode heating has been shown to mitigate anode disintegration, allowing for multiple shots on a 1-mm-OD anode.
