Effectiveness of physical material shields in reducing atmospheric muon flux
(2022-06)In this experiment we studied the ability of lead to shield against cosmic ray muons. We built detectors that used plastic scintillators, silicon photomultipliers, and amplification circuits. We filtered out other ionizing ... -
Using Beta Decay to Find the Mass of a Neutrino
(2022-06)The goal of this experiment is to measure the mass of a neutrino via the study of beta decay. The motivation for this is to see how well a crude laboratory set up can determine the mass of a neutrino in comparison with the ... -
Refraction of a Laser Beam in Various Mediums Due to Ultrasound Waves
(2022)Gas-Coupled Laser Acoustic Devices (GCLADs) are systems used to detect sound using a laser [1]. If implemented in a bubble chamber (a type of experiment used for particle detection [2]), the sounds made by bubbles forming ... -
Electron spin resonance spectrum of pyrene and N,N-dimethylaniline free radicals
(2022-05-24)In this experiment, the objective was to use ESR to determine the minimum number of quantum entanglements that occur in a free-radical system. This was done by creating a saw-tooth shaped magnetic field generator that ... -
Measuring the Work Function of Metals Through the Photoelectric Effect
