RESEARCH AND INVESTIGATION ON RADIATION RESISTANT, HIGH TEMPERATURE THERMIONIC CIRCUITRY
Abstract
TIMM tube research and development efforts were continued in the areas of electrical and mechanical design, materials evaluation, component fabrication and evaluation, module fabricationAND RADIATION EFFECTS STUDIES AND EVALUATION. Triode grid investigation programs were continued with emphasis being placed on improvement of previously used tensioning techniques and the evaluation of new techniques and means to stretch the mesh and to control grid flatness in the finished device. An optical grid transparency measuring instrument has been designed and is currently being used for 100 per cent sorting of grids. Programs are continuing to design a hexagonal mesh grid, equivalent to the 0.004 x 0.040 rectangular mesh, for improved mechanical strength. A TIMM pentode is being developed for improved electrical performance. Design parameters are discussed and desired electrical characteristics and cross section views of the device are presented.
