The calorimeter was used to reconstruct photons and electrons with energies ranging from a few GeV/c2 to over 100 GeV/c2 in 300 GeV/c pion and proton interactions on a lithium target at instantaneous interaction rates approaching several MHz. Construction details of the calorimeter are given. The readout electronics, calibration, and algorithms used to reconstruct the positions and energies of showering particles are discussed. Energy resolution, position resolution, and reconstruction efficiency are assessed using both calibration electron beams and electrons and pi0 mesons reconstructed in 300 GeV/c interactions. ER -
