Special Features:

Lh=low hysteresis model, application a, b, y, sensitivi type 3500, window area densi type 1.8-2.0, window effictive diameter 44.5, 1.75, recommended operating voltage 900, plateau slope 10, dead time 50, background 30 max, test circuit figure 1, resistor, r 3.3, resistor, r1 1.0, operating temp -20 to +55, cathode material cr/fe, width 31.7/1.25 inches, length 53.6/2.11 inches

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).
