The numerical design of a resonant extraction system for the MURA 50-Mev electron accelerator /

Detailed numerical investigations of a proposed half-integral resonant-extraction system for fixed-field, alternating-gradient synchrotrons verify the feasibility of extracting a high-quality beam from the MURA 50-Mev FFAG by this method. The half-integral resonance causes a large growth in the radial betatron amplitude, enabling the extraction of virtually the entire beam with an exceedingly small emittance. The method is complicated by the inclusion of time-varying parameters, required to maintain a relatively constant emittance and apparent source in the extracted beam over the extraction interval. Calculations were performed on an IBM-704 digital computer using measured magnetic fields.Research supported by the U.S. Atomic Energy Commission through ANL subcontract 31-109-38-1707."TID-4500 (37th Edition).""UC-28: Particle Accelerators and High Voltage Machines.""March 1, 1965."Caption title.Includes bibliographical references (leaves [25]-[26]).Detailed numerical investigations of a proposed half-integral resonant-extraction system for fixed-field, alternating-gradient synchrotrons verify the feasibility of extracting a high-quality beam from the MURA 50-Mev FFAG by this method.
