Data collection using a coaxial test setup terminating into a 50/spl Omega/ load line to simulate a matched impedance system allows very fast risetimes. Transmission line type current sensors and capacitive voltage dividers with temporal resolution of 300 ps provide information about the discharge voltage and current. Steady, DC currents ranging from a few nA with less than 10 kV of applied voltage, to a few /spl mu/A prior to full breakdown are measured using an electrometer. Prebreakdown events are measured with positive and negative charging voltages with respect to ground. Light emission from the discharge is measured using a series of fast photomultiplier tubes, (risetimes 800 ps), that observe positive and negative electrode tips and center of the channel. Preliminary results on self-breakdown (breakdown voltage +44 kV) with a 2.35 mm gap show a DC (seed) current of several hundred nA with prebreakdown spikes of a few mA immediately before final breakdown. Periodicity of the current spikes combined with a general increase in magnitude prior to full breakdown has been observed. Data collection using a negative charging line, with respect to ground with enhanced field at the cathode, indicates current spikes that are typically 25 to 50% faster than spikes using a positive charging line with enhanced field at the anode. Detailed optical diagnostics along with high-speed electrical diagnostics of the pre-breakdown phase will address the physical mechanisms initiating volume breakdown.","PeriodicalId":143385,"journal":{"name":"Digest of Technical Papers.

In the simplest geometry of such an antenna-amplifier, an annular beam propagates outside a dielectric rod antenna, and the drive signal is in the fundamental non-axisymmetric HE/sub 11/ mode. We present the first antenna-amplifier simulation results obtained using the 3-D version of the MAGIC particle-in-cell (PIC) code. Gain and beam bunching have been demonstrated for an X-band signal entering into the system in the TE/sub 11/, mode of a circular waveguide. The linear amplifier response was observed as well as saturation at increased interaction length. In addition, the effects of the generation of harmonics of the main frequency, found earlier in one-dimensional modeling, have been verified. Furthermore, the possibility of controlling the harmonic content in the output spectrum by means of input frequency variation, also studied earlier in 1-D simulations, has been confirmed. As the frequency changes within the amplification band, the output power remains the same, and spectral peaks shift to the new frequency and its harmonics, but the harmonic content in the spectrum changes significantly.","PeriodicalId":143385,"journal":{"name":"Digest of Technical Papers.

The set up employs a cable discharge into a coaxial system with axial discharge and load line to simulate matched terminating impedance. A unique feed-through design creates no discontinuities in the system lines through the discharge chamber. The impedance of the system is matched at 50 ohms including a novel design for impedance matching transitions from discharge cable to coaxial system to load line allowing for a sub-nanosecond response. This paper presents results on self-breakdown with voltages of up to 60 kV. Self-breakdown is achieved by charging the discharge cable and load line to +/-30 kV respectively. Transmission line type current sensors and a capacitive voltage divider with fast amplifiers/attenuators are used in order to obtain a complete range of information from amplitudes of 0.1 mA to 1 kA with temporal resolutions of 300 ps. Optical measurements include high speed photography and shadowgraphy. Detailed optical diagnostics along with high-speed electrical diagnostics will address the mechanism initiating/assisting biodegradable oil volume breakdown.","PeriodicalId":143385,"journal":{"name":"Digest of Technical Papers.
