This paper summarizes the development of a distributed x-ray source with up to 60kW demonstrated instantaneous
power. Component integration and test results are shown for the dispenser cathode electron gun, fast switching controls,
high voltage stand-off insulator, brazed anode, and vacuum system. The current multisource prototype has been
operated for over 100 hours without failure, and additional testing is needed to discover the limiting component.
Example focal spot measurements and x-ray radiographs are included. Lastly, future development opportunities are
This paper presents a progress update with the development of a distributed x-ray source. We present a high level
summary of the source integration, simulation and experimental results, as well as challenges in electron beam focusing,
beam current gating, voltage isolation, and anode technologies. We present focal spot measurements, x-ray images and
a summary of our distributed x-ray source concept.
