Abstract
High-energy gamma-photons have been produced by an intra-cavity Compto n Back Scattering (GBS) process between the Super-AGO Storage Ring Fre e Electron Laser, at 350 nm, and an ultra-relativistic (800 MeV) posit ron bunch. No spatial selection of the beam has been made so a wide en ergy range of gamma-photons has been directly (NaI detector) and indir ectly (CBS positrons bunch life-time) investigated. The high intra-cav ity laser power leads to a high gamma-photons emission rate (5 million s ph/s). Some future possible improvements are proposed. (C) 1998 Else vier Science B.V. All rights reserved.
