- The four rails inside BCAL that will support the FDC, CDC, and the mesh were installed, but not adjusted. Survey of the BCAL position has been done, but we haven't seen the results yet. Next, depending on the BCAL position, the rails have to be aligned, that will take several days survey people working there. If they can't be adjusted to the nominal distance, as it was adjusted already on the three installation carts, we will have to re-adjust the distance between the rails on the cart. It will not be easy to adjust the rails on the cart where the FDC is, but Bill says it's doable. | - The four rails inside BCAL that will support the FDC, CDC, and the mesh were installed, but not adjusted.

| − | - The techs will start soon the installation of the FDC platform. The space between the two rails on the platform (holding the carts) is very small, it will be very difficult to work at the bottom side of the packages. The racks have not been installed yet, first cable holes have to be cut. The electronics will not be installed until all the dirty work is finished. | + | - The techs will start soon the installation of the FDC platform.

| + | - We discussed if the BCAL cabling and infrastructure installation will interfere with the FDC installation. Bill: before we can start cabling FDC, the water ring (for the cooling) has to be installed on the bore of the magnet. It's not clear if the Nitrogen cooling, cables for the control system, also has to be installed in advance. Not all of these subsystems are ready, some has not been decided yet. Beni proposed to ask Elton to explain their plans on the next FDC meeting so that we can synchronize our activities. | ||
