Continuous Operation of a 250 KW Thyratron
Abstract
ITT ETD has designed, fabricated and delivered three (3) high power thyratrons, Type F259, in which the use of a dispenser cathode is a major design improvement. By substituting the dispenser cathode in lieu of a conventional oxide coated structure, ITT is attempting to develop a device of extremely high average current compatibility (500 amperes is the Phase III objective). Present state of the art is eight ( 8) amperes. Two ( 2) of the F259' s have been tested by ETDL using it's high power modulator facilities. Both of these tubes have demonstrated the feasibility of operating above the Phase I objective of 18 ampheres. Continuous operation for several hours at an average current of 20 amperes and at a repetition rate of 1000 hertz has been achieved. A third tube was delivered to Lawrence Livermore Laboratory where it is currently being evaluated in the Free Electron Laser modulator. Testing is continuing to establish the ultimate peak current capability and barium depletion characteristics on life.
