The University of Maryland Electron Ring (UMER) is a scaled storage ring using low-energy electrons to inexpensively model beams with high-space-charge. With the ability to inject bright beams comes the problem of longitudinal end erosion of both the head and tail. It is important therefore to apply suitably- designed longitudinal focusing forces to confine the beam and prevent it from its normal expansion. Successful operation of an induction cell system for this purpose would push the achievable number of turns and also enable us to perform studies of the longitudinal physics of such highly space-charge dominated beams. The pulsed voltage requirements for such a system on UMER would require ear-fields that switch 3kV in about 8ns or so for the most intense flat-top rectangular beam injected into the ring. This places a considerable challenge on the noise-free delivery to a compact core.
