We present the results of tests made on two types of uranium/liquid argon calorimeter modules, one electromagnetic and one hadronic, constructed for the D0 detector at the Fermilab Tevatron Collider. For electrons and hadrons with energies between 10 and 150 GeV, we present measurements of energy resolution, linearity of response, electromagnetic to hadronic response ratio (e/π), and longitudinal hadronic shower development. We have also investigated the effects of adding small amounts of methane to the liquid argon.

Abstract The DO experiment at the Fermilab Tevatron Collider is currently studying proton-antiproton collisions at a center-of-mass energy of 1.8 TeV. The data-acquisition system for the experiment was designed with two independent pathways for communication between the front-end computers, which interface with the detector electronics, and the host-level computers, where the event data is logged and where the experiment is monitored and controlled. The event data path employs multiple, high-bandwidth, unidirectional busses while the control path, which uses standard local area network components, handles all control, configuration setting, alarm, and monitoring communications. This paper discusses the software components associated with the control communication path, with emphasis upon the design philosophy, user interface, database, and networking issues.
