Fig. 6.49 View of one module of the ATLAS hadronic barrel calorimeter. Sixty-four such
modules complete the cylindrical detector. Each of the longitudinally oriented scintillating tiles
is instrumented with two wavelength-shifting fibers [141]
Fig. 6.50 Longitudinal quarter view of the Atlas calori-meter facility. The outer radius is at 4.2 m;
it extends along the beam direction to ±7 m. Auxiliary instru-mentation in the gap between the
calorimeters allows energy correction for the non-instrumented zones [120]
