Abstract :
The Photoinjected Energy Recovery Linac (PERL) design study at the NSLS is considering the feasibility of a new synchrotron light source based on a 3-7 GeV energy recovering superconducting linac injected by a laser photocathode RF gun (photoinjector). In addition to returning the electron beam to the linac with a phase shift of 180 degrees, the "return loop" of the PERL must be capable of longitudinal bunch compression, minimize the deleterious effects of coherent synchrotron radiation and provide space for up to two-dozen insertion devices. We present a design for the PERL optics based on tuneable achromats
