Test results of a liquid krypton/argon electromagnetic calorimeter with accordion type electrode structure are presented. The test was carried out at the Brookhaven AGS in a negative beam with good electron identification at momenta 5, 10, 15, and 20 GeV/c. Results on energy resolution, linearity, pointing resolution, and muon response are presented. The results are in good agreement with Monte Carlo calculations. The energy resolution of 6.7% E was achieved using liquid krypton and 7.7% E with liquid argon, with a negligible constant term.
