- Dave for the spare package: Two wire planes (#2 and #3) have been deadened, two more remaining. The filed wire on #2 was fixed (broke during deadening). It turned out we don't have enough HV cables (short cables with male connectors) that are soldered on the wired frames, and we have order them. This is because we originally planned for 4 spare cells. 
  
- Package #3 repair: we scanned all the wires of the HV sector #2 (on the wire frame of cell #6) using the camera of the motion station on the stringing table. There were three field wires with some stuff we could not clean. We disconnected these wires from the HV side, by un-soldering and cutting the end of the wire, but without success: the HV problem remained. Then we removed half of resistors at the HV side of the sense wires and the problem went away. Using this method we went down to 5 questionable wires, and at this moment Anatoly found a tip of a sense wire (~5mm) sticking out of the solder. After fixing this, the chamber now is holding HV already 10 hours. We will wait till tomorrow and then Casey will replace the three field wires, so the wire plane will be ready for installation by Monday. Bill suggested to glue/tape somehow the spacer ring to the wire frame when mounting it from the back of the package; will need more people for the cell isntallation.

- Package #3 repair: the three field wires on the wire frame of cell #6 were fixed and on Monday we install the sixth cell on the package upside-down. We ended up holding the spacer ring with fingers
