Multi-Stream Instability of a Single Long Electron Bunch in a Storage Ring
B. L. Beaudoin, R. A. Kishek, I. Haber +2
A multi-stream instability is observed experimentally in a longitudinally expanding electron beam in a storage ring. The instability is observed when the beam expands such that its…

Quasi-integrable optics for a small electron recirculator
K. Ruisard, H. B. Komkov, B. Beaudoin +3
This paper describes the design and simulation of a proof-of-concept quasi-integrable octupole lattice at the University of Maryland Electron Ring (UMER). This experiment tests the…

Low Space-Charge Intensity Beams in UMER via Collimation and Solenoid Focusing
S. Bernal, B. Beaudoin, L. Dovlatyan +5
The University of Maryland Electron Ring (UMER) has operated traditionally in the regime of strong space-charge dominated beam transport, but small-current beams are desirable to s…
