  • Abstract
    The operation of a new type of crossed-field amplifier called the DEMATRON will be described. This device is in the final stage of development. To date, various developmental models of the DEMATRON have yielded, at X-Band, a pulsed power output of 500 kw, 13 db gain, 15% bandwidth, and 35% efficiency. The DEMATRON is a forward-wave, crossed-field amplifier with non-reentrant beam and wave. It utilizes distributed emission, that is, its cathode extends all the way along the interaction space. Due to its large cathode, the DEMATRON has excellent potential as a low-impedance, very high power tube. Its slow-wave structure which is of the folded waveguide type has exhibited very good thermal characteristics.
