Long-Drift Calorimeter Modules for the Soudan 2 Nucleon Decay Detector

摘要

The first full size 5-ton detector modules for the Soudan 2 nucleon decay experiment have been assembled and operated. Modules consist of a hexagonal array of drift tubes and corrugated steel, instrumented to read out three-dimensional track positions and pulse height. These will be assembled to form an isotropic, continuously sensitive, self-triggering detector. Details of the design, construction, operation and performance of the modules are discussed. 7 refs., 10 figs. (ERA citation 11:014215)
