Abstract

Hadron calorimetry apparatus and techniques as used in the Fermilab Tagged Photon Spectrometer Facility are described. This paper concentrates on the iron-acrylic scintillator device which is used in conjunction with an upstream lead-scintillator electromagnetic shower calorimeter. Distributions of energy deposit are given which can be used for Monte Carlo simulations of hadronic showers in such devices. We also present results on calibration, energy resolution and stability. The uses of the system in triggering on hadronic events in a photon beam and in the observation of neutral hadrons are described.
