Production

- Dave: The construction tracking attached above has different structure now; it has the spare package with the first four wire frames (new epoxy used there) ready. Lubomir: as demonstrated with cell#2 just drying them for a week with nitrogen and/or Ar/CO2 would be enough to have them operational. Outside in the dirty area techs are laminating now the wire frames for the first package. After that (according to Dave) it will take less than a week per wire frame to finish the first package. Wire frame #5 was strung, wires taped and will be glued with the old Epoxy.

- Dave: we tested the electro-plating procedure this time on a full-scale wire frame, the one that was built at IUCF and shown on the open houses. Before that the frame was cleaned and HV applied to it in air. We were able to put on the two middle sectors 2200V with low current. Two issues related to the procedure were discussed: -- First, how to bypass the 1MOhm resistors on each wire and
