Cathodic arc deposition of barium oxide for oxide-coated cathodes

Summary form only given. Cathodic arc deposition is used to create a barium oxide plasma which is then deposited/implanted onto a cathode nickel substrate. The primary motivation for this work is the critical need for a reliable, repeatable thermionic cathode for the production of high power, micros...

Summary:Summary form only given. Cathodic arc deposition is used to create a barium oxide plasma which is then deposited/implanted onto a cathode nickel substrate. The primary motivation for this work is the critical need for a reliable, repeatable thermionic cathode for the production of high power, microsecond duration microwave pulses.
