Embedded Charge Distributions In Electron Irradiated Polymers – Pulsed Electroacoustic Method Reproducibility And Calibration, Zachary Gibson, Jr Dennison, Ryan Hoffmann
Physics Student Research
The pulsed electroacoustic (PEA) method has been used to measure the embedded charge distributions in electron irradiated polymers. The PEA method allows for non-destructive direct measurements of embedded charge distributions in dielectric materials. Samples of polyether-etherketone (PEEK) and polytetrafluoroethylene (PTFE) of 125 μm or 250 μm thickness were tested after irradiation with either a 50 keV or 80 keV electron beam. The reproducibility of the PEA method and the experimental conditions were studied by: (i) measuring each sample multiple times in a given mounting configuration, (ii) re-measuring each sample after repositioning them in the PEA test fixture, and (iii) measuring …
Fundamental Aspects Of Black Holes, Jacob Fisher Ciafre
Fundamental Aspects Of Black Holes, Jacob Fisher Ciafre
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The literature study here seeks to present the foundations of black hole physics in General Relativity. The report includes a discussion of the Kerr black hole metric, black hole entropy, particle creation, the laws of black hole mechanics, and a bilinear mass formula for the Kerr-Newman black hole solution.
