Space Charge Dominated Beams

Patrick O'Shea
University of Maryland

(Note, Different Time!)

A long-term goal of beam physics is the development of ever more intense, high quality beams, but fear of destructive instabilities has limited intensity. Most of our experience is with low-intensity emittance-dominated beams. As we push to higher intensities, space charge becomes more important, in the low energy ends of electron accelerators, and throughout many ion accelerators. Almost all of our understanding in the space-charge region is based on theory, simulation and conjecture, because there has never been an opportunity to perform experiments in the region of deep tune depression, and extreme intensity. At the University of Maryland, we have established an experimental program to study the physics of beams at extreme intensity. We have several test stands, the most significant of which is the University of Maryland Electron Ring (UMER), currently under construction. UMER has been designed to study the physics of beams with extreme intensity in a strong focusing lattice with dispersion. I will discuss some of our recent work and future plans.
