Design and Construction Features of a Variable Gap Thermionic Converter Tube

PDF Version Also Available for Download.

Description

Design and construction features are presented for a parallel-plane thermionic converter tube which has an interelectrode gap that may be precisely varied from zero to six inches. (auth) 3Z72 Thermionic diodes and pentodes (with their associated circuitry) were compared as elements in logarithmic current amplifiers. Diodes generally give greater accuracy, but pentodes have simpler associated circuitry and hence may be preferred for certain applications. Logarithmicto-linear transfer characteristics and stability were investigated for a number of tube types, and selected types were operated with heater voitage, current, and resistance separately held constant to examine the effects on long term drift.

Two logarithmic current amplifiers, one of them designed for radiation resistance, are presented as well as two methods of utilizing vacuum tubes as dynamic logarithmic current sources. (auth)
