We describe the design and operation of a detector system for measuring all-photon decays of mesons photoproduced in a tagged photon beam with energies between 4.3 and 5.4
GeV and a flux of

tagged photons per second. Photons from meson decays were detected with a lead-glass calorimeter with an energy resolution of 11% at 1
GeV. Various veto and trigger components were also present. Final states with as many as six photons were successfully detected and reconstructed.
