Abstract

Construction has recently begun on the University of Maryland Electron Ring (UMER). This system will be used to investigate the physics of space-charge-dominated electron beams. Beam centroid drift and beam current will be investigated on a sub-bunch timescale (<50 ns). A capacitive beam position monitor (BPM) with good temporal (<5 ns) and spatial resolution (<0.5 mm) is being constructed for these measurements. Seventeen of these BPMs will ultimately be installed in the ring and will also be used for computer-assisted steering of the beam. In this paper we report the successful construction and testing of the second-generation prototype BPM
