-- 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) and were replaced. 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-1 cathode is ready, two type-3 waiting for the daughter cards to be glued. Wire frame for the second cell is ready for stringing.
+- Dave: wire board #20 (first cell of the 3rd package) is ready for wire deadening; waiting for the microscope results from Olga to make sure the new timing/currents for electroplating is OK.
 - Testing wire deadening with new diameter for the last two packages: Bill recalculated the currents/timing and one sample was made. It turned out the surface looks more rough that before (see microscope picture attached). Bill will add another electro-polishing cycle to smooth the surface and will try it on another sample.
