At the heart of the DO/ detector, which recently started its maiden data run at the Fermilab Tevatron pp̄ collider, is a finely segmented hermetic large angle liquid argon calorimeter. We present here results from the latest test beam studies of the calorimeter in 1991. Modules from the central calorimeter, end calorimeter, and the inter‐cryostat detector were included in this run. New results on resolution, uniformity, and linearity will be presented with electron and pion beams of various energies. Special emphasis will be placed on first results from the innovative technique of using scintillator sampling in the intermediate rapidity region to improve uniformity and hermeticity.
