| − | - Caleb: Bill is busy, but he explained well details of the outer (outside of the FDC) part of the cooling system that will have Fluorinert and water loops. Caleb will work with Bill also on the testing of the cooling system. | + | - Without Bill we discussed the grounding hardware: if we want to use Rohacell or the rubber material suggested by Bill for filling the void between wire and cathode frames. Since we will have of the order of 100 such blocks per package, Simon said it's too much material and we better use Rohacell. |

| − | - Chris: LV cables have come. We discussed that it is worth setting up the LV system in 126 and later connecting the LV cables to the third package (when it will be in 126) but not applying voltage on most of them since we will need cooling. | + | - Nick: no news, waiting for different parts, grounding clips, LV stuff, to come. |

| − | - See the document above prepared by Vlad. It contains (in Excel format) a table of all the signal cables showing the label and the destination rack, crate, module, and connector. There's a scheme at the end of the document: half of the cables will go to the left and half to the right racks depending where the corresponding card is. Wire cables will be connected to F1TDCs, 6 modules per package per side occupying two crates with 12 modules each. 5 crates on each side will be filled with 15/14 fADC125s, having 18 modules per package per side. We decided to keep the channel information in the label (like FDC1,C5,D85B-108B). | + | - Vlad showed the new scheme |
| − | | + | |
| − | - The ordering of the connectors is generally (from left to right in the crates) starting from the lower package, cell number, channel number. Beni suggested that we may want to split the cards with highest rates into different fADC modules. It's easy to implement, but we want to discuss this with Fernando, Cody, Gerard.
