Abstract

We describe the performance of a large (0.9 × 1.4 m2) liquid argon photon calorimeter in high energy experiments at Fermilab. Resolutions for π0 and electron showers, obtained under data-taking conditions, are compared with electron-beam calibration results. Exceptional spatial and time resolutions have been achieved for isolated showers (σx,y <0.7 mm and σt ∼6 ns). Electron data up to energies of 80 GeV and π0 data up to 180 GeV are presented.
