Title: Advanced High Power mm-Wave Microwave Devices Final Report CRADA No. TC-0287-92

Abstract

The purpose of this CRADA was to improve existing high-average-power microwave devices and develop the next generation microwave devices for energy and defense applications. A Free Electron Maser was under test at the FOM Institute (Rijnhuizen) Netherlands with the goal of producing a lMW-long pulse to CW microwave output in the range 130GHz to 250GHz. The DC acceleration and beam transport system is eventually to be used in a depressed collector cotilguration requiring 99.8% beam transmission in order that the high voltage 2MV supply be required only to supply 20 milliamps of body current. A relativistic version of the Herrmann optical theory originally developed for microwave tube beams was used to take into account thermal elections far out on the gaussian distribution tail that can translate into beam current well outside the ideal beam edge. This theory was applied to the FOM beamline design and predicts that the beam envelope containing 99.8% of the current can be successfully transported to the undulator for a wide range of assumed eminence values.
