Special Features:

Manufacturer classification: beam triode; envelope material: metal; weapon system essential

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).
