Also, we will need more people when pulling/pushing the cables through these holes.

- We discussed what to do with the systems that are absolutely needed for the FDC installation but will not be ready before the installation starts: gas, electric power and cooling. Gas: Dave will check what has been installed and how it can be modified. Beni: if some of the 500 ccpm flow controllers have been installed already then we don't have enough for a temporary gas system, i.e. we have to disconnect them

Beni: if some of the 500 ccpm flow controllers have been installed already then we don't have enough for a temporary gas system. Electric power: for the LV crate we need 208V which would require a portable transformer. Fernando volunteered to check the availability and what else is required to power the LV crate (the minimum needed to start cabling).

- The moving date will depend on the readiness of the above (temporary or permanent) systems. In any case it can't be next week (Eugene) because in case of a shutdown the FDC better be in the EEL. Eugene needs information from Lubomir and Beni to include the FDC check (of the gas flow) in the lists of the critical tasks in case of a shutdown. The AC in 126 is already included.

- Bill was not at the meeting but sent an update before: Casey has de-burred the plastic angles for the skin, but is busy now in the Hall. We need him however to install the skin on the FDC. We need a tech to work on the mesh in ESB; all the parts including the new side support, are there.

- The skin between the FDC packages has been installed by Bill and Casey, also Tina today. Tomorrow (probably) Casey will install the tubes between the cooling manifolds.

- Fernando: full crate test of the new F1TDC is done, the crates are ready to go in the Hall. Cody is working on the crate test of the fADC125.

- Half of the signal cables have been labeled by the summer students and we decided to label the rest. The cables for one package were moved from Blue Crab in August and can be labeled. The rest of the cables (also one package) has been used for the full electronics test. We started disconnecting these cables and most are packed back in their original boxes in 126. When Beni is done with the F1TDC test next week we will finish the rest.

- Spare package has been re-configured to test the new F1TDC, using cell #3 (all cathode and wire cards connected) and #6 (only wire card connected). Vlad did all the grounding on cell #3 and some on cell #6.

- Beni showed his results of the F1TDC tests in the following configuration: two regular cells (3 and 6) with +HV of 2150

- Beni can read out the TDCs but needs a reference trigger signal for the timing. The reference that was used before in another crate with the old F1TDC doesn't work because the crates are not synchronized. Spacial cable will be made by Chris and Nick to put the trigger signal in the new F1TDC. We discussed if and how many of these trigger signals we will need in the Hall.
