Old Rack Layouts

The following drawings are sketches of the various ideas for laying out the trigger racks, mainly for the calorimeter trigger, in USA15. Since I drew these, there have been many changes - in particular there is no central gap in the racks on niveau 2, and only a small gap on niveau 1.

Figure 1

First thoughts: whole of the trigger on niveau 1. Requirements for the muon trigger were (then) unknown.

Figure 2

More variations.

Figure 3

Even more variations.

Figure 4

Trying to use both floors (muons upstairs).

Figure 4

After changes agreed with Technical Coordination group: calo trigger upstairs (niveau 2) with a small gap in the racks (before they finally agreed to no gap).
