APPLIED RESEARCH ON A HIGH-POWER MILLIMETER-WAVE GENERATOR
Abstract
Efforts were continued to demonstrate the feasibility of generating very high power, specifically 100 kw peak and 1000 watt average at 100 Gc by means of an O-type backward-wave oscillator operating at very high voltage. During the eighth quarter, experimental tube No. 3 was completed and some test data has been obtained. Testing of tube No. 3 will be continued during the next quarter of the program. Peak and average power have been measured at 107 kw and 215 watts respectively. Very recent results have shown average power of over 300 watts. The 435-1C gun is used in tube No. 3. Test results show improved focusing with a reduced magnetic field as compared with guns used in previous tubes. The rf output power is terminated in helical stainless steel waveguides. These rf loads are water cooled for use with the calorimeter for average power measurement. A tungsten insert was used to collimate the electron beam at the anode to prevent peak heating damage to the disk loaded waveguide circuit.
