Radon In Utah Homes, Madison Mackay
Radon In Utah Homes, Madison Mackay
Physics Capstone Projects
Radon gas can be found nearly everywhere. It is formed by the decay of radium, which is found in rocks, soil, plants, and animals. Radon gas can become trapped in buildings and is dangerous at high levels. It is particularly known to be high in many areas of the state of Utah. It is important for the average citizen in Utah to understand more about radon and what levels they may be exposed to. An experiment was done to try an alternate, faster method of testing for radon gas. This experiment was performed in several different locations in Utah. While …
Preparation, Characterization And Electron Yield Analysis On Highly Insulating Granular Particles, Heather Allen
Preparation, Characterization And Electron Yield Analysis On Highly Insulating Granular Particles, Heather Allen
Physics Capstone Projects
This study focuses on obtaining reliable electron yield measurements of highly insulating granular particles of various shape, size, and composition. Measurements of this kind have long been considered too difficult to collect on granular samples due to experimental complexities leading to a critical knowledge gap in the fundamental electrostatic behaviors of dust. A significant portion of this study was spent on preparing and characterizing granular samples before any type of measurement took place. Particles of varying sizes ranging from ~1 μm to ~100 μm, shapes including cubical, spherical, and angular, and composition including NaCl, MgO, Al2O3 and …
Engineering Lab Building Telescope Manual, Aidan L. Tueller
Engineering Lab Building Telescope Manual, Aidan L. Tueller
Physics Capstone Projects
In partnership with Dr. Jan Sojka, head of the Physics Department, a plan was created to make the telescope on top of the Engineering Lab building operational again for either staff, students, classes, or labs to use. The telescope was purchased through funds by Utah NASA Space Grant Consortium. This paper will contain basic information about how to operate the telescope and use its equipment. There is an online manual from Meade that is much longer but goes into much more detail about individual pieces and specific parts of the telescope.
Metasurfaces For Holography, Scott Howell
Metasurfaces For Holography, Scott Howell
Physics Capstone Projects
Holography uses the interference of light waves to store information about an object, which can then be seen from different angles to create a partial 3D view. A simple experiment can be done using a laser diode, photographic plate, and a set of dice to create a holographic image. The holographic film is thin and can only hold a single image. Reflection holography can create a 3D diffraction pattern and allows more information to be packed into a single medium. Computer generated holograms can be designed to create holograms without a real object to be used in augmented reality. High …
The Kp Index And Behavior Of Quiet Periods, Collette Walbeck
The Kp Index And Behavior Of Quiet Periods, Collette Walbeck
Physics Capstone Projects
The Kp-index quantifies the electromagnetic effects in the Earth’s atmosphere and is used in a variety of scientific fields. Higher Kp values tend to be the focus in these fields as they relate to high solar activity and geomagnetic storms. This study aimed to examine the significance, if any, of lower Kp indices. A simple data analysis was performed on continuous sequences of low Kp values, deemed Quiet Periods. Both the daily average of the values and the full set of Kp data were used. A decaying exponential relationship was discovered between the length of these periods and their frequencies …
High Frequency Radio Communication, Tyler Larsen
High Frequency Radio Communication, Tyler Larsen
Physics Capstone Projects
High frequency radio communication has been the most reliable form of communication for many decades. Over that period, we have learned and experienced times of enhanced signals along with complete radio blackouts. The purpose of this research is to collect and analyze radio signal data to see the evidence of various reasons as to why these phenomena occur. A radio antenna was set up at USU campus to retrieve the signals from beacon networks across the globe that transmit signals every 15 minutes. By tracking a few of these signals we can locate the times of discrepancies in the signals …
Effectiveness Of Multilayer Graded-Z Forms Of Radiation Shielding, Brinley Packer
Effectiveness Of Multilayer Graded-Z Forms Of Radiation Shielding, Brinley Packer
Physics Capstone Projects
This study explored how different forms of radiation shielding were more or less effective than standard single-layer shielding. Beta and gamma radiation sources were used and measured using a Geiger counter to determine how well the various forms of shielding protect against the radiation. The shielding effectiveness of standard homogeneous materials (e.g., graphite, carbon/epoxy composites, aluminum, and lead) of various thicknesses for different radiation sources was measured to provide standards for comparison. Once a basis of effective shielding was established, the study can go into greater depth into how to use shielding materials to be more effective, to better shield …
