Abstract :
A periodically focused, metal-ceramic traveling-wave amplifier that produces 100 kw peak power at 1290 Mc is described. The unique features of this tube are a gridded, convergent flow solid-beam electron gun that can be operated at perveance 
and a structure design that allows the tube to be operated with the cathode, input and output coaxial lines, and body shell at ground potential and the collector at high voltage. The tube operates at about 23 kv de and 14 amperes peak beam current. The grounded cathode design greatly simplifies the grid modulator problem, particularly in complex phased-array applications.
