                      8 Leaf cards shown in grey. Those that do the jet finding are the 3+3

                                                connected to the two Wheel cards, shown in blue, where the jet shorting

                                                is taking place. The 2 Wheel cards and the two electron Leaf cards are

                                                connected to the concentrator card, shown in green, that does the final

                                                data processing and communicated with GT, DAQ and local VME.

 

Optical format is used to concentrate the data in 8 cards that run all the GCT Algorithms:

3 Source Cards per RCT  Crate handle 6   80-MHz ECL cables that carry the RCT data:
