[Experimental high energy physics using electromagnetic energy calorimetry]

In the current year, the major part of the research on this contract was focussed on the construction of the DO detector, testing of production modules (as opposed to prototypes) and in actual coding of tracking software. We are contributing in two areas to the DO Project: the calorimetry, where we are involved in coordination, construction and testing of the central and end calorimeter modules, the test beam program and software development; and the central drift chamber being constructed at Stony Brook and for which we have developed the electronics, test facilities, tracking and general purpose software
