Abstract :
Results on the performance and details of the design of an iron-scintillator hadron calorimeter are presented. A full absorption array of 87 calorimeter modules was assembled and tested at Fermilab. The central core of this array consisted of 48 modules with 2.8 cm iron sampling thickness by 10-13 cm width arranged in towers of modules three deep along the beam (shower) axis for a total of about 8 absorption lengths. The energy resolution of the calorimeter is given by 30%/¿E for electrons and 92%/¿E for hadrons. This resolution is compared with previous results and is found to be in good agreement with the expected resolution for this sampling thickness. The position resolution for single hadron showers is about 2 cm.
