Abstract: (IEEE)
Collisions of light photons with relativistic electrons have previously been used to produce polarized ¿-ray beams with modest (~10%) resolution, but relatively low intensity. In contrast, the LEGS project (Laser+Electron Gamma Source) at Brookhaven will produce a very high flux (>2Ã107 s-1) of background-free polarized ¿ rays whose energy will be determined to a high accuracy (¿E =2.3 MeV). Initially, 300(420) MeV ¿ rays will be produced by backscattering UV light from the new 2.5(3.0) GeV X-ray storage ring of the National Synchrotron Light Source (NSLS). The LEGS facility will operate as one of many passive users of the NSLS. In a later stage of the project, a Free Electron Laser is expected to extend the ¿-ray energy up to 700 MeV.- TALK
