CU Group Work
Our group at CU has created a number of plots that describe specifically the calorimetric resolution studies we are doing using GEANT3.0:

Mike Duckwitz studied the resolution of the small detector design and Aaron Preston carried out the resolution studies of the large detector design. Initially they studied the electromagnetic and hadronic calorimeter separately. These were thick enough that no energy leaked out the back or sides.

In the small detector the electromagnetic calorimeter consisted of 2mm of Tungsten and 0.3 mm of Silicon. The hadronic calorimeter consisted of 2.0cm of Copper and 0.5 cm of Scintillator.

In the large detector the electromagnetic calorimeter consisted of 4mm of Lead and 1.0mm of Scintillator. The hadronic calorimeter consisted of 8.0mm of Lead and 2.0 mm of Scintillator.

The results of their work, which is shown in the plots below, is described in a paper which shows the detail of their results. This work is in here.

In all these plots shown the particles are incident normal to the detector.
