Electrical properties of Xe-filled thermionic diodes in nuclear reactor core radiation, obtaining I-V curves in radiation induced plasma between electrodes
Microwave power generation using arrays of varactor diodes, noting distributed heat sources and technique for preventing spurious parametric oscillations
Use of small silicon diodes as radiation dosimeters in proton beams
Crystal-diffraction spectrometer, combined with a lithium-drifted Ge-diode detector, performs high-resolution gamma ray spectroscopy on the complicated neutron-capture gamma ray spectra. The system is most useful in the 1-3 MeV energy range and improves the signal to background ratio.
Stripline varactor harmonic multiplier uses a device for positioning the varactor diode with respect to the stripline circuit to obtain series resonance. The device also reduces detuning effects, due to thermal expansion, over a wide temperature range.
Improved method fabricates electroluminescent planar P-N gallium arsenide diodes. GaAs is masked with silicon monoxide to allow P-type impurities to be diffused into unmasked portions of GaAs to form P-N junctions.
Backward-diode pressure transducer retains the advantages of a tunneling mechanism, requires no shunting resistor, operates at a low voltage level, and consumes little power.
