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 modules c
onsist of finely segmented iron instrumented with 1 m long drift tubes
of 15 mm internal diameter. The tubes enable three spatial coordinate
s and dE/dx to be recorded for charged particles traversing the tubes.
The spatial resolution is 0.38 cm in the x-y plane and 0.65 cm in the
z, or drift, direction. The operation and performance of the modules
are discussed.
