"Kickin' It with UMER: Overcoming a Space-Charge-Induced Dilemma"

by Will Stem

Friday, September 21, 2012 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Research Asst. Prof. Tim Koeth

The University of Maryland Electron Ring (UMER) is a high intensity circular machine that is dedicated to the study of long path length space-charge-dominated beam physics on a small scale. Over multiple turns, longitudinal space charge effects cause the tail and head of an electron bunch to expand and interpenetrate, eventually resulting in a "DC beam." This leads to complications when trying to measure the beam with UMER's AC-coupled diagnostics. Three techniques are developed to recover the information within the beam. The DC beam profile can then be studied over long trajectories and the existence of any loss mechanisms can be determined.
