Show Abstract
A theoretical model for the plasma erosion opening switch (PEOS) is presented which predicts its voltage, current and impedance history as a function of the input waveforms, geometry, and switch parameters. Scaling relations for the switch operation are developed from this model. System requirements for pulse compression and power multiplication using inductive storage are derived from a simple lumped circuit analysis and a transmission line analysis. These requirements are shown to be satisfied using the PEOS as a fast opening, vacuum switch in a configuration relevant for existing high‐power accelerators. The switch model is incorporated into a transmission line code for comparison with recent inductive storage experiments. Code results agree well with the data showing conduction times of ∼60 ns and switching times of ∼10 ns with peak currents of ∼600 kA.

Show Abstract
We have studied the ablation driven momentum transfer to single and layered planar targets, irradiated by a 1‐GW, 5‐nsec Nd:glass laser in the intensity range 1011–1013 W/cm2. The results show an effect of lateral energy transport on the scaling of momentum with laser intensity. Corroborative evidence for this is presented from experiments on thin foil targets.

Show Abstract
The operating characteristics of glow‐discharge‐created electron beams are discussed. Ten different cathode materials are compared with regard to maximum electron beam current achieved and the beam generation efficiency as measured calorimetrically. Specific electron gun designs are presented for a variety of applications that include: cw ion laser excitation; electron beam assisted chemical vapor deposition of microelectronic films; and wide area annealing of ion‐implantation damage to silicon substrates. The use of sintered metal‐ceramic (e.g., Mo‐Al2O3) cathodes to generate multikilowatt electron beams in a pure noble gas discharge is reported. Cathode materials with high secondary electron emission coefficients by ion bombardment allow for electron beam production in glow discharges at 50%–80% generation efficiency values.

Show Abstract
Experimental contact noise spectra of Na β″ alumina and Ag β″ alumina ceramics at room temperature exceed low‐frequency thermal noise for both blocking and ohmic electrodes. Contact noise spectra above 102 Hz for ohmic electrodes of sodium amalgam and NaI in propylene carbonate agree with Nyquist noise levels determined from ac impedance measurements, and the low‐frequency excess noise is shown to be associated with nonequilibrium electrochemical processes. Similar effects are found for ohmic silver amalgam and aqueous AgNO3 electrodes on Ag β″ alumina. Greatly increased voltage fluctuations are observed to accompany current in the sample, and both contact current noise and bulk granular current noise have similar characteristics. A total dc charge flow fo 25 C/cm2 at sodium amalgam electrodes to Na β″ alumina increases both contact and current noise many orders of magnitude and can be returned to initial levels by equivalent reverse charge flow. No corresponding changes in conventional experimental measurements, e.g., current‐voltage characteristics, are detected.

Show Abstract
In physical systems, we encounter phenomena well described by the continuum percolation as often as those characterized by the lattice percolation. However, the conductivity data of the continuum percolation are scarce compared to those of the lattice percolation. With this situation in mind, we consider here two types of two‐dimensional continuum percolation problem and compute, by the finite element method, the critical volume fractions of the metallic elements for the metal‐insulator transition. We also compute the conductivities. The geometrical configuration of the first (or second) type is formed by random deposits of square metals (or holes) of the same size and orientation on an insulator substrate (or on a metal). The critical volume fractions are calculated to be, respectively, 0.58 and 0.42. We compare the computed conductivities with results from the effective‐medium approximation and from the extended Watson–Leath equation, with the measurement of Smith and Lobb and with the conductivities of composite materials having a regular structure.

Show Abstract
Thermally induced changes in work function and surface composition of a sputter‐formed Re‐1%Mo alloy have been measured. Segregation of Mo to the alloy surface was accompanied by a decrease in surface work function. The relationship between surface composition and work function change fits the Topping model of dipole layer formation with dipoles being formed by electron transfer from Mo to Re. Values for the dipole moment at zero field and the polarizability of Mo on the surface of Re were found to be (5.27±0.36)×1030 C m and (74.1±10.1) Å3, respectively. The direction of charge transfer is consistent with published electronegativity values for Mo and Re, but its magnitude of 0.126 electrons per atom was significantly smaller than the charge transfer in the bulk expected upon alloy formation.

Show Abstract
Superconductive wires containing 78 filaments of Nb3−xTaxSn for 4–16 at. % Ta were produced using the external bronze process to yield a composite with an overall composition 21.4 wt. % Nb–Ta, 64.9 wt. % Cu, and 13.6 wt. % Sn. Reaction periods of 20 to 260 h at temperatures from 650 to 735 °C were used. Critical‐current densities over the entire wire cross section were 5×104 A/cm2 at 14 T and 1×104 at 19.7 T, the measured Hc2 was 27 T at 4.2 K for wires with 8 μm filaments containing approximately 4 at. % Ta. Single filament wires using a 13 wt. % bronze matrix were fabricated to determine the effect of Ta on reaction kinetics. The A15 layer thickness was approximately proportional to the square root of the reaction time and independent of tantalum concentration. The critical‐current densities are discussed in terms of A15 grain structure, stoichiometry, filament uniformity, and Hc2 enhancement.

Show Abstract
We report experimental measurements of the ratio of the tunneling resistance of edge junctions at ∼4 and ∼300 K. The results, after correction for the contribution of the electrode resistance in the normal state, are compared with theory. The temperature dependence measured in these Nb–NbOx–Pb‐alloy junctions is greater than the theory for a simple trapezoidal ∼0.5 eV high barrier. Nevertheless, the consistency of the ∼4 and ∼300 K tunneling resistances is adequate to allow the use of the resistance at ambient temperature as a process monitor in Josephson junction circuit fabrication.

Show Abstract
Thermomagnetic generators allow direct conversion of heat energy to electrical energy. Temperature cycling about or near the Curie temperature causes changes in magnetization, resulting in time variant magnetic flux and induced voltage in a surrounding conductor. Numerical analyses of regenerative thermomagnetic generators with perfect regeneration have been performed for three working materials: iron, gadolinium, and Ho69Fe31. Power density above 20 W/kg of shunt material and efficiency approaching Carnot limits are possible over temperature differences of 50 K. Analytical studies performed during the 1950s predicted maximum power density less than 7 W/kg and efficiency less than 1% for nonregenerative cycles.

Piezoelectricity and pyroelectricity in vinylidene fluoride/trifluoroethylene copolymers

Show Abstract
Piezoelectric and pyroelectric properties have been investigated in the 52/48, 65/35, and 73/27 mol % copolymers of vinylidene fluoride and trifluoroethylene. The transverse and longitudinal piezoelectric constants as well as the elastic constant were determined for undrawn samples as a function of the remanent polarization Pr created by a room‐temperature poling. The elastic constant shows a significant increase with increasing Pr. Thus, the d constant (polarization/stress) tends to saturate at high Pr. On an assumption of elastic isotropy, true e31 and e33 (polarization/strain) were calculated. It is found that e33 is proportional to Pr with a coefficient of −1.2 in three copolymers while e31 is almost zero. The results indicate that the piezoelectric activity in undrawn copolymers primarily arises from macroscopic dimensional changes while molecular dipoles are rigid. The pyroelectric constant p3 and the thermal expansion coefficient α3 were also measured in mechanically‐free samples. By the use of e31, e33, and α3, the contribution from the secondary effect was evaluated and found to be smaller than 1/4 of the total activity. The primary effect due probably to disordering of crystalline dipoles seems to play a major role in the pyroelectricity of the copolymers.

Show Abstract
We present data on the speed of light‐induced refractive index changes in a BaTiO3 single crystal. The light‐induced erasure rate of a refractive index grating is shown to depend on optical intensity as Ix where x<1. The exponent x depends weakly on temperature and increases from 0.62±0.02 to 0.71±0.02 when the temperature is varied between 12 and 40 °C. The sublinear dependence of rate on intensity implies that higher optical intensity is required to achieve high‐speed operation of BaTiO3 devices than previously thought. The dark erasure rate has an anomolously strong temperature dependence; it increases by a factor of 50 over the same temperature range. We have also determined that the number density of photorefractive charge carriers is 6×1016 cm3 in this crystal.

The necessary properties for such a material are described. Reverse saturable absorption is demonstrated at 488 nm in alexandrite. A simple model describing these effects is presented.
