A lead-glass hodoscope calorimeter that was constructed for use in the Jefferson Lab Real Compton Scattering experiment is described. The detector provides a measurement of the coordinates and the energy of scattered photons in the GeV energy range with resolutions of 5 mm and 6%/sqrt(E{gamma} [GeV]). Features of both the detector design and its performance in the high luminosity environment during the experiment are presented.
