    When a photon pulse impinges on a cavity, it causes electrons to be emitted from the cavity walls, thereby producing electromagnetic fields in the cavity. This constitutes what is known as Internal Electromagnetic Pulse (IEMP). The produced fields for a given incident photon pulse and spectrum (in the case where transient space charge effects are important) is calculated by means of a particle-in-... View full abstract»

    Space-charge limiting of current transmission can be neutralized by introducing gas into the diode. The relationship between gas pressure and transmitted current is determined by a combination of several basic physical processes. A model that can predict experimental observations over a wide range of pressures is utilized to show which processes dominate current transmission in various pressure ra... View full abstract»

    Experimental data on space-charge dissipation due to gas effects has been obtained using electron pulses from an accelerator injected directly through a thin film and a metal screen into a small experiment chamber. The current transmitted across the chamber was measured as a function of gas pressure, gas composition, chamber depth, and electron collector impedance. The measurements generally confi...

    Experiments were performed to measure IEMP coupling to cables in small cavities for non-space-charge limited conditions. The experiments were designed to separate the magnetic field, electric field, and charge deposition coupling modes. Investigations were made of the effects of cavity pressure, cable bias potential, and cable type and termination. A theoretical model was developed which represent... View full abstract»

    Recent investigations have been directed toward gaining insight into the effect of electrical pulse overstressing in integrated circuits, especially simple gates and bipolar LSI arrays. In order to determine the effect of ionizing radiation on the pulse-power failure susceptibility levels of small scale, monolithic, junction-isolated integrated circuits (simple gates), an experimental study was un...

    The electromagnetic response of a dielectric-filled finite-length cylindrical cavity, exposed end-on at the Hermes II radiation facility, is experimentally and theoretically examined. Loop sensors were used to obtain azimuthal magnetic field related signals, and a dipole grid sensor was employed to acquire axial electric field related signals. The favorable comparison achieved between the experime... View full abstract»

    Subminiature coaxial cables smaller than RG-58 were exposed to intense pulsed irradiation from a plasma focus device, and the currents induced on the center conductors were measured in a vacuum environment. The incident photons had energies mostly below 70 keV, and filters were used to vary the average hardness of the irradiation. The measured cable responses in units of Coulomb/rad(Si)-cm were co...

    The theory of multiple dielectric relaxation times in an irradiated transmission line is developed in detail for strip lines and coaxial lines. The problem of deposition profiles, photo-Compton currents, and dielectric properties which vary arbitrarily is treated first; then the treatment is specialized to layered dielectrics. A numerical scheme is given for solving the resulting system of equatio... View full abstract»

    Techniques for modeling multiconductor transmission lines for use with the SCEPTRE computer program are presented. The transmission line models developed can be modified for compatibility with other circuit/ system transient analysis programs and are amenable to modification to include nuclear weapon effects. The general modeling approach has been to develop computationally efficient and accurate ... View full abstract»

    We have developed a computer program BOLT for the numerical solution of the Spencer-Lewis equation for kilovolt electron transport in finite slabs. The method of solution used is a discrete ordinates method utilizing Gauss-quadrature angles equivalent to a 20th order Legendre polynomical expansion of the electron flux distribution function. The ultimate goal of the program is to compute x-ray phot... View full abstract»

    An analytical procedure for describing vacuum photoemission from one dimensional materials more than one electron range thick has been developed. The magnitude, angular and energy distributions are expressed in terms of bulk Photo-Compton current information by algebraic formulae. A semi-empirical equation for the low energy component (<100 eV) is also presented. Comparison with experimental data ... View full abstract»
