-- Dave: Working on the sixth (last) wire frame for the first package; all wires soldered and today will do tension measurements. The fifth wire frame will be populated tomorrow by Chris. On Monday we will do the wire deadening on that frame and then it will be ready for stacking. Started working on the end windows and first cathode for the package #2.
+- Dave: First package is was fully installed as of yesterday. Now working on the second package. The first cathode (type-3) is ready. Working on different
 - We have four cells in the first package as of Tuesday evening. Finally we fixed the gas leak in the second cell (at the third attempt): a bubble in the epoxy inside  the chamber (that seals the gap between the solid part of the g10 and the PCBs) made a path for the gas to leak. A missing part of the trace  on a signal wire in the third cell was fixed by Dave. All the channels of all the wire planes and cathodes were checked with a generator prior the installation. We had to replace the top spacer ring because it turned out after the first installation that the gas openings were not drilled there. Bill proposed to check the flow trough the gas openings relatively, using a rotarmeter with a fixed impedance.
