Measurement Of Angle-Resolved Secondary Electron Spectra, Robert Davies
Measurement Of Angle-Resolved Secondary Electron Spectra, Robert Davies
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Theoretical formulations of secondary electron emission over the past 20 years have exceeded the confirming ability of available measurements. An instrument has been developed and tested for the purpose of obtaining simultaneous angle- and energy-resolved (AER) secondary and backscattered electron measurements for energetic electrons incident on conducting surfaces. The instrument is found to be in good working order and the data quality found to be excellent for nearly all angles and energies investigated. A representative set of AER measurements has been acquired for 1500 eV electrons normally incident on polycrystalline gold. The data have been used to construct angle-resolved (AR) …
