LINEAR RESONANCE ANALYSIS OF BEAMS WITH INTENSE SPACE CHARGE IN THE UNIVERSITY OF MARYLAND ELECTRON RING (UMER)

Space charge can significantly affect the resonant prop-erties of rings. The University of Maryland Electron Ring is a scaled experiment in which we have circulated beams with unprecedented intensities. Here we discuss the res-onance analysis performed using the electrostatic particle-in-cell code WARP, to understand the effect of space charge on the ring resonances. Beams with varying degrees of space charge in both the emittance-dominated and space-charge-dominated regimes are attempted. The operating point is scanned to map the tune diagram under various lattice and injection errors. The results of the simulation study are compared to experimental measurements
