Study on the initial development of high-power millimeter wave sources. Final report

Under NRL contract number N00173-77-C-0215, JAYCOR has performed an analytic and experimental study of some of the fundamental aspects of cyclotron masers (gyrotrons). In particular, JAYCOR has designed and tested a high power gyrotron oscillator, and has designed and used a gyrotron testing facility. This report discusses the results of this project in detail. The JAYCOR-NRL contract includes the following work statement: (1) Design and test a 200 kw cyclotron maser testing facility which includes the modulator, pulse transformer, power supply, superconducting magnet, and auxiliary subsystems. (2) Design and test maser components to include the RF interaction structure and output coupling network. (3) Design and test the RF instrumentation package to include a millimeter wave calorimetric load and an output mode analyzer. (4) Test and evaluate the magnetron injection gun to be used in the cyclotron maser. Compare measured performance with theoretical predictions and optimize gun performance. (5) Design and test the RF driver package. Essentially this work statement calls for the design of a laboratory for the testing of cyclotron masers and the design and test of the various components of an initial device.
