Tina and Mike are cutting/gluing new foils; Anatoly tested already the six new foil sets that we have received. Anatoly started gluing the daughter cards on the cathodes that were done before. Priority is to finish the two type-3 cathodes that will be needed in any package configuration. |

| − | - On package #1 Vlad installed the ground connection before | + | - On package #1 Vlad installed the ground connections before Thanksgiving, then this week we installed the cooling loops and yesterday Chris and Nick started working on the HV cabling. The package will be ready at the beginning of the next week. We decided not to install the cooling manifolds so far: we don't need them now and in case we need to open the package we will not be able to re-use the cooling tubes. |

| − | - Vlad finished testing package #1. All channels are working fine. Three pre-amps are oscillating, but the channels are working if using other cards at the same places. Two of the cards have been replaced already with new ones, still the same problem. After ground installation we hope the problem will disappear, if not we can replace the cards later. | + | - Package #4 was assembled just before Thanksgiving |

| − | - Package #1 was disassembled from the mounting table, we still have three metal pins in the package. It was moved to granite table and Vlad just finished the installation of the grounding clips. Next step (probably tomorrow) will be the installation of the cooling tubes. Bill made a tool to place the tube ends in the proper positions and cut them, then install the plastic manifolds. He explained how to fix the tubes during this procedure so that they don't apply pressure on the cards/cathodes.

| − | - We plan to move the third package back to Blue Crab on Monday. We will take from it the strong-back, needed for testing the package #1 at 126, and the hubs needed to finish the installation of package #4. On Tuesday we plan to install the last two cells of package #4. It will be flushed with gas over Thanksgiving and Vlad will test it the week after Thanksgiving. Package #1 will be moved to 126 for testing the first week of December.

| − | - 6 sets of cathode foils have been shipped on Monday. Probably they will not be able to make 18 sets with the material they have. Bill found that the 2micron-copper/Kapton foil is still available. Eugene suggested to buy material for 14 sets. Bill will ask for a quotation for 14 and 24 sets.
