The experimental part of this paper includes the testing of spark gap models. Two spark gap types were tested: one having the third electrode inside the main electrode and one having a separate third electrode, both being insulated by vacuum or gas (under pressure, providing the same operating voltage as for a vacuum insulated spark gap). Both types of spark gaps were theoretically sized in the optimal way. Several characteristic are determined experimentally: (1) the influence of the gas and vacuum insulation parameters on the spark gap functioning and (2) the influence of the rate of rise and injected energy of the triggering pulse on the spark gap functioning. Two types of gases were applied: SF/sub 6/ gas, N/sub 2/ gas and three vacuum (residual) pressures: 10/sup -1/ Pa, 10/sup -4/ Pa, and 10/sup -6/ Pa. Also, three electrode materials were used: copper, steel and tungsten. The spark gap switching time and delay time are measured.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

Holography offers the unique capability to record distributions of particles over a three dimensional volume. The system to be discussed is used to measure particle distributions of ejecta emitted after a cylindrical aluminum liner (5.0 cm in diameter, 2.0 cm high) impacts a target (3.0 cm in diameter). The ejecta emerge from the target traveling up to 7 mm//spl mu/s and moves toward the axial center of the system where the holographic imaging is performed. In-line holography is particularly suited for the Pegasus pulsed power facility where the geometry restrictions make off axis holography impractical. In order to record the fast moving particles a frequency-doubled Nd:YAG laser system has been implemented which produces a 80 ps 20 millijoule pulse at 532 nm. An optical relay system composed of a Fourier optical lens pair has been developed which is placed 4.0 cm from the center of the region of interest. This relay lens pair forms an intermediate image 32 cm from the object plane and the hologram is placed 4 cm downstream from the intermediate image. The holographic system and resolution capability is discussed.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

In this paper, a modulation technique is described which compresses ultra wideband (UWB) signals on conventional LPDAs. In transmit modes, high power microwaves (HPM) applications are found with wideband transmitting antennas, such as LPDA, where the matched filters are the antennas. The strong phase dispersion usually encountered with LPDAs creates substantial distortion in the shape of wideband signals or pulses. This distortion is greatly reduced with either a change in the FM from linear to exponential or with a modification in the log periodicity of the array elements to a linear periodicity.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

It would store /spl sim/100 MJ in the Marx generators and deliver /spl sim/500 TW to drive high power z-pinch implosions. The pulsed power requirements for Jupiter were evaluated by a national review panel which concluded that the modular IVA technology as used in HERMES III is capable of meeting these requirements. Modularity of construction permits design verification with less than a full size system and offers the flexibility to meet changing requirements. A program to validate this approach at the required power levels has begun with the construction and testing of components that will comprise a full scale IVA generator module. The IVA module will provide a nominal 10 MV, 1.8 MA, 100 ns FWHM output pulse and will consist of four submodules. Each submodule is composed of a Marx generator, two intermediate energy storage capacitors (ISCs) four pulse forming lines (PFLs), one voltage adder cavity (VAC), plus other associated switches and hardware. A conceptual design for this IVA module has been completed. Initial designs for the ISC, PFL, and their gas switches are also complete and hardware has been procured. Testing of these components is underway at Sandia National Laboratories. Discussions of these designs and results of tests are presented in this paper.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.
