Multipurpose Pseudospark Switch for High Energy Electron Beams

CFDRC announces the award of US patent # 7,579,578, “Advanced Multipurpose Pseudospark Switch”. This invention provides increased electron beam brightness, lower beam emittance, and higher average electron energy than existing e-beam generators. This invention provides e-beams for applications such as free electron lasers, high power magnetrons, and compact x-ray generators and can be used as a high power switch for laser and microwave HV units, capacitor discharge, and crow bar protection; and in materials processing applications such as cutting, drilling, and film deposition.

“We have achieved improvement in e-beam quality over a classic pseudospark switch by strong ionization of gas inside a hollow cathode chamber, prior to main gap breakdown,” stated Mr. Sami Habchi, EVP, Aerospace & Defense Solutions at CFDRC. CFDRC plans to pursue multiple opportunities within the high energy beam industry as well as contribute to breakthroughs in ongoing particle physics research and development.
