THE X626 HIGH POWER KLYSTRON DEVELOPMENT PROGRAM
EITEL-MCCULLOUGH INC SAN BRUNO CALIF
A NEW METHOD FOR MODULATING ELECTRON BEAMS FOR PULSE APPLICATIONS AND LINEAR AMPLITUDE MODULATION SYSTEMS, by George M. W. Badger. Paper presented at the I.R.E. Convention, 26 Mar 57, 7p. incl. illus. The development is described of the X626 klystron and the equipment necessary to build and test the tube. The tube was designed as a final amplifier for high duty, long pulse, continuous radar service and was built to combine in groups of 2 to 8 tubes for high peak power 10 Mw operation at 400-450 mc. The X626 will deliver over 1.25 Mw peak power and over 75 KW average power at approximately 100 kv beam voltage and approximately 1.9 amperes average beam current, with a gain of 26 db. The X626 is a three cavity, externally tunable, modulating anode, pulsed type, liquid and forced air cool d, unipotential cathode, insulated collector, 400-450 mc, amplifier klystron. Author
