- The last, "frozen" schedule changed just by a couple of days. Now the FDC insertion is in the middle of January 2014, dictated mainly by the electronics. Since the testing outside of the magnet should start much earlier we must be able to test the different packages connecting to the same electronics. | - The last, "frozen" schedule changed just by a couple of days.

Fernando insisted that we have to keep the cables fixed to the racks at the downstream end and never un-bundle them. In this case the question is where to put the extra bundles that are 6-7m long after the insertion of the FDC: if possible somewhere at the front of the magnet?? |

| + | - Installation of the cables from the two bottom quadrants will be difficult because of the small opening going to the bottom (below the platform) trays. Bill had an idea to elevate the racks so that the space below them will be accessible from the front so that the cables can run there. This makes the cable installation much easier, but requires taller people to service the electronics. Other options: 1) disconnecting the cables from the electronics before FDC insertion and re-connecting them again after the insertion (Lubomir), but has to be done every time we take FDC out of the magnet. 2) Putting all the cables on the top side of the racks (Eugene), but the length might not be enough and it will be more difficult to work there. | ||
