    The characteristics of TRAPATT oscillations in a p-in diode are discussed and an approximate semi-analytical solution for the diode voltage waveform is derived when the diode current is a square wave. It is shown that a traveling avalanche zone is not necessary to generate a dense "trapped" plasma and that the boundary conditions prevent the trapped plasma from completely filling the depletion lay...

    Experimental evidence is presented which distinguishes two mechanisms whereby an avalanche diode can efficiently generate microwaves at transit angles below those of classical transit-time oscillations. Measurements of external current waveforms and subsequent calculations of terminal voltage waveforms demonstrated that efficient generation (η ∼10 percent) of microwaves was possible at ...

    The dynamic pyromagnetic response of several materials with magnetic phase transitions near 300°K has been measured by a method initially described by Chynoweth [1]. The results indicate that practical broad-band pyromagnetic radiation detectors operating in a fast dynamic thermal mode are possible. The best results were obtained with gadolinium and manganese germanide crystals which have sec... View full abstract»

    The address and drive circuit requirements of dc gas discharge display panels are described with particular reference to devices developed by Weston and Hall [1]-[3] and de Boer [6.] Drive systems are being developed for displays both with and without inherent memory. The choice of system available is dependent both on the type of information to be displayed and the characteristics of the discharg... View full abstract»

  • Operating modes of a pulsed 50-GW diode

    Operational characteristics of a 50-GW high-field-emission diode are discussed in detail. The diode is shown empirically to have two distinct modes of operation, with corresponding impedances, which depend on the diode aspect ratio, pressure, and total voltage and current. The first mode indicates rectilinear electron flow, with impedance shown to be about ½ that predicted by the Child-Langmu... View full abstract»

  • A flame sensor for high-temperature ambients

    The flame sensor consists of a photoelectric counter tube which is triggered by ultraviolet photons emitted by flames in the spectral region beyond the solar cutoff. Tubes of this type have been made previously, but this new tube differs in being able to operate in ambient temperatures up to and in excess of 1000°F. The new tube has high sensitivity and a lower operating voltage than older tu... View full abstract»
