Installation preparations

- Bill: for the cooling system in the Hall if the hard piping is not ready we can still have a temporary solution using plastic pipes. However, we need chill water supply.

- Expectations are to start the FDC installation sometimes in October. Before that we need to install the skin and do some small fixes on the FDC: fix the HV connectors, replace a couple of pre-amps. Need also to connect the cooling system between the packages.

Engineering

- Bill showed his new design of the mesh attachment using the main rails (drawings attached). Additional support at the end of the mesh, right between the CDC and FDC is needed; done with a stock T-shape Al profile (1/8"). Similar structure would be needed even with the old design using additional rails for the mesh attachment. The bearing for the mesh is glued to a holder. Same bearing is at the other (upstream) end of the mesh but it is removable. The drawings show also the plate connecting the packages and the grounding cable.
