- Dave: second package ready, working now on the third. First wire frame strung today, two end windows and one type-1 cathodes ready, working on two type-3 cathodes and started type-2. Dark current was tested on the PCBs for the next wire frame (we are doing this test now both before and after frame lamination).

- Dave: working on the first cell of the third package. Wire frame was strung, but two field wires (next to each other) showed lower tension (106g instead of 130g nominal, but actually mean measured value is around 120g). Could be because of local frame deformation so that wires are touching the board with some friction, so when raising the wire frame try not to touch the wires. Could be also some garbage on the pulley or on the rod. One type-3 cathode is ready, the other waiting for the dauth

- The thick copper tube that was put on two cells of the first package was removed. Today we received the thinner tube that will be installed on all the cells. Dave and Anatoly labeled the HV connectors. Fernando and Chris will come next Tuesday to do the HV connections, by that time we should be ready with the cooling tubes.

- Tooling needed for the installation of the third package: we will re-use half of the hubs from the first two packages. Bill asked if we need new transfer ring: no. Beni talked to Roger: do we need more foils from Allflex, no; what should we do with the extra foil material at Minnesota, should be shipped to us.

- The last cell of the second package was installed on Friday and was tested this week successfully. Will flush it with gas till the beginning of the next week and do some more tests.
