APPLIED RESEARCH ON A HIGH-POWER MILLIMETER-WAVE GENERATOR
Abstract
Investigations were continued to demonstrate the feasibility of developing a backward-wave oscillator capable of generating 100 kw peak power and 1000 watts average power at 100 gc. A beam tester was completed and tested at voltages to 35 kv. Beam transmission of 95.5% was achieved through a 70 mil diameter drift tube 1 in. long by using auxiliary magnets to cancel leakage magnetic field in the region of the cathode. A new anode with an internal flux shield was designed to reduce the stray fields in the cathode region to an acceptable value. A thin mica window was successfully sealed by compression between two copper washers. A silicon carbide waveguide termination 0.77 in. long was developed with a reflection coefficient under 30% from 7085 gc. (Author)
