A Laser Synchrotron Source (LSS) experiment is in progress at the Naval Research Laboratory to demonstrate the generation of monochromatic, tunable x-rays by Thomson backscattering of laser photons from a relativistic electron beam. Laser photons from a Nd:Glass laser at 1.053 micron wavelength are backscattered from a 4.5 MeV electron beam generated by a one and a half cell S-band RF gun. Experimental progress and the observation of x-ray photons will be reported.
