Construction of the Laser Electron Gamma Source (LEGS) began at Brookhaven in October 1983. When completed, the source will provide intense beams of monochromatic and polarized gamma rays with energies in the range of several hundreds of MeV. The planned layout of this facility with its experimental areas is shown. The gamma-ray beams will be produced by Compton backscattering uv laser light from the electrons circulating in the 2.5-3.0 GeV X-RAY storage ring of the National Synchrotron Light Source (NSLS) at BNL. The X-RAY ring is currently running with 50 mA at 1.7 GeV, and is expected to reach 2.5 GeV by November 1984. There is as yet no firm schedule for operation at 3.0 GeV, although some initial testing should be completed by the end of 1986. The availability of the 210-420 MeV LEGS beam will depend upon these 3 GeV studies.
