“…For example, many of the important characteristics of the beam transport can currently be measured only by employing the intersecting diagnostics relevant to the first turn alone [1,[10][11][12]. Beam emittance, mismatch, the consequences of skew errors in the magnets, and transport in the beam source and injection region, as well as the characteristics of the injection ''Y'' itself, are suitable for first-turn measurement using intersecting diagnostics such as the insertable phosphor screens.…”

“…For example, any systems with the same space-charge intensity, as defined by the parameter w discussed below, is similar to any beam system with a similar geometry and source characteristics and the same intensity parameter. Some examples of systems whose parameters can be accessed by the physics in University of Maryland Electron Ring (UMER) are presented elsewhere [1].…”

The University of Maryland Electron Ring (UMER) is a low energy, high current recirculator for beam physics research. The electron storage ring has been closed and recent operations have been focused on achieving multiturn transport. An entire suite of terminal diagnostics is available for time-resolved phase space measurements of the beam. These diagnostics have been mounted and tested at several points on the ring before it was closed and will complete the ring when mounted to the extraction section. UMER utilizes a unique injection scheme which uses the fringe fields of an offset quadrupole to assist a pulsed dipole in bending the beam into the ring. Similar concepts, along with a more traditional electrostatic method, are being considered for beam extraction. This presentation will focus on the recent efforts to design and deploy these major subsystems required for beam extraction.

The University of Maryland Electron Ring (UMER) is a scaled model to investigate the physics of such intense beams. It uses a 10-keV electron beam along with other scaled beam parameters that model the larger machines but at a lower cost. Recently, multi turn operation of the ring (3.6 m diameter) has been achieved. In order to have full current transport of the electron beam, and to increase the number of turns of the beam around the ring, injection of the beam from the straight section into the ring becomes crucial. In this work, we report experimental results from the injection and matching of a space charge dominated beam and an emittance dominated beam. We also describe and analyze two methods of injection of the electron beam from the straight section into the ring. In one of the methods, the two injection quads are fixed to a preset value, while in the other both the injection quads are switched off (Collins injection).
