Gordon Dix and Dr. Tim Leishman, Physics and Astronomy Designing and constructing a world-class concert hall is the culmination of many different, yet interrelated, disciplines. The architects must make the building structurally sound, while preserving its aesthetic beauty. Electricity, water, air conditioning, heating, and many other aspects of the inner workings of the hall must […]
A Practical Approach to Specific Heat-Phonon Spectrum Inversion
Thomas C. Butler and Dr. William E. Evenson, Physics and Astronomy Inverse problems have long provided researchers in a variety of disciplines with fruitful and challenging problems with immense applicability. However, as early investigators discovered, most of these problems are ill-posed.1 This means that the existence of the solution is not guaranteed, and even if […]
Determining Ruthenium’s Optical Constants in the Spectral Range 11-14 nm
Luke J. Bissell and Dr. David Allred, Physics and Astronomy Introduction Computers are getting faster, and as they do, computer chips are getting smaller. Photolithography is a process used to design nanoscale patterns on a computer chip. In photolithography, the image of a circuit pattern is transferred from a mask to the semiconductor wafer. This […]
Towards Maximization of Gain in a Capillary Discharge Plasma
Robert Bradford and Dr. Steven Turley, Physics and Astronomy I. Introduction Due to the high energy of soft x-ray radiation, coherent x-rays are rather difficult to produce. The most common source of x-rays is bremsstrahlung, or breaking radiation. Brehmsstahlung is produced by accelerating an electron across a potential, and then rapidly decelerating the particle, giving […]
Selectivity of Silicon Dioxide on planner Graphite
John Wilcox and Dr. Robert Davis, Physics and Astronomy BYU’s Nanotube Research Group is currently searching for a method to attach and shorten carbon nanotubes (CNTs) on the tips of Atomic Force Microscope (AFM) probes (image 1). Many have shown that short CNTs grown on the end of AFM probes greatly enhance the resolution and […]
Variable Star Research from the MUSK Observatory
Miriam Stevens and Dr. Clark Christensen, Physics and Astronomy For my project, I planned on using the telescope at the Musk Observatory to study the variable star IP Uma. The MUSK Observatory is located about five miles away from the small town Hanksville, UT at the Mars Desert Research Station(MDRS). I have had several opportunities […]
Understanding the Absorption Edge Energy Shift of Thorium Dioxide, Uranium Oxide, and Uranium Nitride in the EUV *Or* Optical Applications of Uranium Thin-Film Compounds For the Extreme Ultraviolet and Soft X-ray Region
Richard L. Sandberg and Dr. David D. Allred, Department of Physics and Astronomy Recently, the extreme ultraviolet (EUV) and soft x-ray region of the electromagnetic spectrum (between about 1 and 100 nm in wavelength or 20 eV to 5 keV photon energy) has become increasingly important in technological applications. The next generation of optical technologies […]
Characteristic Acoustical Properties of a Theater in the Round
David Nutter and Dr. Timothy Leishman, Physics and Astronomy Architectural Acoustics is a field of study with many applications in building design, including office spaces, concert halls, and recording studios. Theaters must be carefully designed so that the speech intelligibility of actors is adequate for the audience. Since theater design is varied and unique to […]
Diode Laser Stabilization
Brian Neyenhuis Over the course of this grant, we have made considerable progress on our laser. We tested an anti-reflection coated diode in our setup, and although the anti-reflective coatings appear to be good, we did not see considerable improvement in scan range. However by experimenting with the geometry of the laser and implementing current […]
Charactering Titanium Dioxide by use of Transmission Electron Microscope
Jason Neff and Dr. Richard Vanfleet, Department of Physics and Astronomy The original title submitted for my research was “Stacking Faults in GaN”. This study was aimed at employing the use of the Transmission Electron Microscope (TEM) to understand and image defects in the crystal lattice of Gallium Nitride (GaN) that lead to stacking faults.
