Abstract :
Design and performance characteristics are presented for a high-power bar-line-type traveling wave tube: TOP 1304. Peak power up to 220 kW and average power of 2.5 kW have been measured on a 15% bandwidth. The tube utilizes a sturdy copper delay line derived from French TPOMI (M-type traveling wave tubes) bar lines, the TWT is operated in the fundamental space harmonic. Although the beam is solenoid focused, a PPM system with conventional magnetic material could be integrated with the tube because of the small outside diameter of the delay line.
