Abstract :
Summary form only given. With the ability to inject bright beams into the University of Maryland electron ring (UMER) comes the problem of longitudinal end erosion of both the head and tail from high space charge. It is important therefore to apply suitably-designed longitudinal focusing forces to confine the beam and prevent it from its normal expansion. This paper presents the design and prototyping of an induction cell and the technology used to pulse this cell. With successful operation of the induction cell, the confinement of the beam within UMER would increase the number of turns and also enable us to perform studies of the longitudinal physics of such highly space-charge beams. The pulsed voltage requirements for a confinement system on UMER would require ear-fields that switch 3 kV in about ~8 ns or so at a maximum rate of 5 MHz 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.
