Special Features:

A200 w, cw traveling-wave amplifier; 7.5 ghz to 16.5 ghz; periodic-permanent-magnet focused, coaxial input; waveguide output; conduction-cooled; focus-electrode modulated; single-stage collector

Properties:

An inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. The electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. Includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). Excludes items whose primary purpose is to produce light energy. Also excludes photoelectric cell; and semiconductor device (as modified).
