- The short term plan: since we think the survey of the FDC in final position is doable we can go ahead and put FDC back on the platform (on Friday). Then we will move it in and out of the magnet and do the survey in both positions. Tom will have people working on the cable mesh. After it's done we can start cabling. | - The short term plan: since we think the survey of the FDC in final position is doable we can go ahead and put FDC back on the platform (on Friday).

Since then it is continuously flashed with gas and it bubbles normally. We tried to insert FDC in the magnet and it was almost flash with the upstream end of BCAL but got stuck there. The problem was the HV connector caught the head of a screw on the rails (last picture). The size of the heads turned out to be bigger for the rails inside the BCAL. These screws will be replaced (one by one); at the same time the the plates holding the HV connector were modified the move the connector close to the beam. Since Monday the FDC is down on the floor for the survey. It was not possible to do it on the platform. There Casey also connected the cooling manifolds with tubes. |
