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)
