Figure 1. 3D representation of a single event.
Figure 2. A few modules are selected,rotated and zoomed for the same event to better clarify the correlation between the different signals.
Figure 3. Exploded view of an event in endcap A. Each layer is shown with tower signal in red and fired strips in green.The last two layers are in fact the muon chambers with orthogonal strips.
Figure 4. A particle enters a module(in this case a sextant in one of the two endcaps). a)The fired towers and strips can be drawn on the module walls. b)Here the signals are drawn on a kind of map of the module. The color of towers is proportional to the deposited energy. To represent a tower we use the shape of the pad in the last layer.
Figure 5. Single event with the complete map of Hcal and Mdet.
Figure 6. The Hcal monitoring display.The upper palette is used to show the tower signal integrated on many thousands events. The other palette is used to show the digital signal. The Mdet hits are shown in green.
Figure 7. a)Pedestal mean for each tower. b) In this map, neighbouring towers with same color are connected to the same readout ADC. By comparing a) and b) it is clear that some ADC's have lower mean values for pedestals.
