Abstract:
Investigations were conducted to establish the feasibility of building and operating high temperature, nuclear radiation resistant, integrated, thermionic electronic circuitry of high efficiency and long life. Small size heaterless electron tubes, resistors, and capacitors were made of titanium and ceramic materials. Typical characteristic test results for diodes, triodes, resistors, and capacitors are depicted by curves. Preliminary half adder and shift-register circuits were assembled and tested using representative, available components. Studies were made of their tolerances and of their sensitivity to supply voltage changes. The gating system for the shift-register circuitry was developed and is presented along with schematic diagrams of these circuits. Circuit testing techniques are discussed, along with special test equipment modifications necessary for the 580 C environment. A materials investigation program was initiated to develop a protective coating for the titanium electrodes and module interconnections. Author
