"Nonlinear UMER: Steering, Alignment, and Other Fun Topics"

by Kiersten Ruisard

Friday, February 17, 2017 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Assoc. Res. Prof. Tim Koeth

Abstract: The University of Maryland Electron Ring (UMER) is a 10 keV storage ring, used as a testbed for high-intensity beam dynamics. One of UMER's current missions is to test the theory of nonlinear integrable beam optics, a possible solution to intensity limitations in conventional accelerator lattices. This theory proposes:  (1) a recipe for including strong nonlinear transverse focusing in an accelerator while maintaining "integrability" and therefore long-term stability and (2) claims sufficiently strong nonlinearities will suppress resonances that drive beam loss. I describe the planned experiment and then talk about upgrades to steering and alignment that will benefit this experiment. Most of the talk will be about progress of our ability to steer the UMER beam (and know where it is) that is necessary to do detailed transverse dynamics studies like Nonlinear UMER.
