Abstract:

Exploratory research work on irradiated inert gasfilled thermionic diodes. Tubes containing xenon and krypton have been tested in the radiation field of a 5-megawatt swimming pool type reactor, and cathode current outputs in the range of 1 amperesq. cm. have been obtained. Early breakdown effects have been observed in irradiated xenon-filled diodes at voltages as low as 0.3 volt, and this effect appears to be dependent on cathode-anode spacing and pressure. At radiation dosages between 10 to the 8th-10 to the 9th rads hr, the current output of inert gas-filled thermionic diodes increases approximatley linearly with radiation dosage. Experiments to increase output in the power quadrant of the thermionic diode, used as a converter, by the design of low anode work function tubes are also described. Author
