Design and development of an electron recirculator for study of high-current beam dynamics

An electron recirculator is being developed at the University of Maryland for studying the physics of space-charge dominated beams in circular systems. The E-ring has been designed to transport an electron beam of 10 keV, 100 mA, 50 ns in a smooth circular lattice of 11.5 m in circumference, focused by 72 printed-circuit (PC) quadrupole FODO elements, and deflected by 36 PC dipoles. This paper reports the progress and status of the E-ring project.
