Abstract
A tagging spectrometer for the gamma rays produced by Compton backscat tering and bremsstrahlung processes is described. A storage ring bendi ng magnet is used as an electron momentum separator for this spectrome ter in the gamma ray energy range from 30 MeV up to 270 MeV. Factors d etermining the tagging efficiency and the energy resolution are discus sed. The energy resolution is measured by the Compton backscattering p rocess. The tagging spectrometer yields a resolution of 4 MeV and a ta gging efficiency of 95%.
