UNLV Retrospective Theses & Dissertations
The Nevada Shocker is a pulsed power machine composed of a 540 kV (maximum), 4.54 kJ (maximum) Marx Bank in series with a 50 ns pulse forming Blumlein activated by a self breaking water switch. The energy released by the water dielectric Blumlein is guided by a water-filled coaxial line to a vacuum chamber containing a parallel plate diode. A cylinder of Rexolite plastic is sandwiched in between the parallel plate diode electrodes. The applied field mechanically stresses the electrodes on a molecular level generating a shock wave that changes the localized index of refraction. Further during discharge, the applied …

We present a measurement of the branching fraction for the doubly-Cabibbo-suppressed decay D+-> K+pi(0), using 281 pb(-1) of data accumulated with the CLEO-c detector on the psi(3770) resonance. We find B(D+-> K+pi(0))=(2.28 +/- 0.36 +/- 0.15 +/- 0.08)x10(-4), where the first uncertainty is statistical, the second is systematic, and the last error is due to the uncertainty in the reference mode branching fraction.

Using 13.3 fb(-1) of e(+)e(-) collision data taken in the Upsilon(1S-4S) region with the CLEO III detector at the CESR collider, a search has been made for the new resonance Y(4260) recently reported by the BABAR Collaboration. The production of Y(4260) in initial state radiation (ISR), and its decay into pi(+)pi(-)J/psi, are confirmed. A good quality fit to our data is obtained with a single resonance. We determine M(Y(4260))=(4284(-16)(+17)(stat)+/- 4(syst)) MeV/c(2), Gamma(Y(4260))=(73(-25)(+39)(stat)+/- 5(syst)) MeV/c(2), and Gamma(ee)(Y(4260))xB(Y(4260)->pi(+)pi(-)J/psi)=(8.9(-3.1)(+3.9)(stat)+/- 1.8(syst)) eV/c(2).

The application of nanotechnologies for a novel type of position particle detector is the aim of NanoChanT project. Titanium dioxide (TiO2) nanowires are grown in an highly ordered array of parallel nanochannels in an alumina template. The template is obtained from the controlled anodization of an aluminum foil that produces regular pores. Depending on anodization conditions, the diameter of the pores ranges from 20 to 200 nm with 40 to 500 nm pitch. After doping, a pn junction can be obtained from each of the TiO2 nanowire. The junction is inversely polarized and is sensitive to the passage of charged …

A low-power, high sensitivity, very low-cost light emitting diode (LED)-based device developed for low-cost sensor networks was modified with bromocresol green membrane to work as a solid-state pH sensor. In this approach, a reverse-biased LED functioning as a photodiode is coupled with a second LED configured in conventional emission mode. A simple timer circuit measures how long (in microsecond) it takes for the photocurrent generated on the detector LED to discharge its capacitance from logic 1 (+5 V) to logic 0 (+1.7 V). The entire instrument provides an inherently digital output of light intensity measurements for a few cents. A …

Electronic Theses and Dissertations
Antenna-coupled detectors provide uncooled, cost-effective solutions for infrared and millimeter-wave imaging. This work describes the design, fabrication, measurement, and optimization of several types of antenna-coupled detectors for LWIR (8 - 12 µm) and 94 GHz radiation. Two types of millimeter-wave antenna-coupled detectors were fabricated and tested: a slot antenna coupled to a bolometer, and a patch antenna coupled to a SiC Schottky diode. Electromagnetic modeling of the antennas helped guide the design of antennas with better impedance matching to the detectors. Schottky diodes are discussed as detectors for millimeter-wave and infrared radiation, with the goal of increasing the cutoff frequency …

Pulsed laser deposition is used to fabricate multilayered Ge quantum-dot photodetector on Si(100). Growth was studied by reflection high-energy electron diffraction and atomic force microscopy. The difference in the current values in dark and illumination conditions was used to measure the device sensitivity to radiation. Spectral responsivity measurements reveal a peak around 2 μm, with responsity that increases three orders of magnitude as bias increases from 0.5 to 3.5 V.
