Wwm. Allison et al., THE SOUDAN-2 DETECTOR - THE DESIGN AND CONSTRUCTION OF THE TRACKING CALORIMETER MODULES, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 376(1), 1996, pp. 36-48
SOUDAN 2 is a 960-ton tracking calorimeter which has been constructed
to search for nucleon decay and other phenomena. The full detector con
sists of 224 calorimeter modules each weighing 4.3 tons. The design an
d construction of the modules are described. The modules consist of fi
nely segmented iron instrumented with 1 m long drift tubes of 15 mm in
ternal diameter. The tubes enable three spatial coordinates and dE/dx
to be recorded for charged particles traversing the tubes.
