Moshe Katz-Hyman with Dan AkeribDetection and Veto of High Energy Neutrons in the CDMS II Experiment The cryogenic detectors used in the CDMS (Cryogenic Dark Matter Search) experiment are a novel type of device that can distinguish between nuclear and electron recoils. The detector accomplishes this by independently measuring...

Oleg Kogan with Dr. Chih-Jen Sung, (Mech./Aero. Engr.) Quantitative Temperature Measurement in Reacting and Non-Reacting Flows by Vibrational and Rotational Raman Spectroscopy Non-intrusive techniques for measurement of scalar and hydrodynamic structures of a flow field have obvious advantages over the intrusive ones, as they do not modify the flow field...
Marta Lewandowska with Corbin Covault Development of a CCD-Based Photometry System for Atmospheric MonitoringHigh-energy astrophysical gamma rays produce extensive air showers when they strike the upper atmosphere of the Earth. The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) collects the Cherenkov radiation produced in these air showers via an array...
Genevieve Mathieson with Phil TaylorModels of Energy Flow in a Complex SocietyIn recent years, there have appeared a number of alternatives to traditional energy sources. As natural resources are depleted, it becomes more important to find reasonable replacements from these new energy sources. Some of these energy alternatives include...
Cameron McBride with Glenn StarkmanThe Propagation of Light and Gravity through Matter-filled Spacetime with Stabilized Compactified Extra DimensionsThe idea of extra dimensions beyond the usual four is far from new. In the 1920s, Kaluza and Klein postulated an extra dimension in an attempt to unify the theory of gravity...
Brandon Miller with Rolfe PetschekLiquid Crystal Alignment PropertiesAlignment of liquid crystals is essential to a variety of devices and materials properties. First order phase transitions to highly ordered phases (such as the first order phase transition from the nematic to smectic C phase) often result in poor alignment. This...
Tim Peshek with Daniel S. AkeribCharacterization of a Particle Detector for Use in the Cryogenic Dark Matter Search The best evidence for dark matter comes from the observation that the luminous mass in galaxies is too small to account for the measured galactic rotational velocity. Big Bang Nucleosynthesis suggests that...
Christopher T. Sica with Robert BrownA Nuclear Magnetic Resonance-based Desktop Imaging SystemAccording to the principles of Nuclear Magnetic Resonance (NMR), a sample placed in a constant magnetic field and then subsequently exposed to an oscillating magnetic field will respond with a measurable magnetic signal. The goal of this project...
Megan Smith with Ken SingerTrap Spectroscopy in Photo-refractive PolymersThe mechanisms of photoconduction are of great interest due to the role of photoconduction in xerography and photorefractive holography. Photoconduction involves the excitation of electrons in response to light, leading, in the case of the materials of interest here, to...
Andrew Stickrath with Ken SingerOrientational Mobility of Chromophores in Photorefractive Polymer CompositesPolymer composites doped with nonlinear optical species have been shown to have large nonlinear optical susceptibilities, and are of prime interest in the study of photorefraction. These composites consist in part of a moiety responsible for a linear...
