Production
- Started stacking again the package; we have already installed the first cell and the first cathode of cell#2. The second cathode of cell#2 and the second wire plane are also ready for installation after replacing two wires (see explanations below). Cell#3: the wire plane is ready except that four broken resistors need to be replaced. The two cathodes for cell#3 were checked with a generator and a problem in one connector was found: attenuation of the signal on several channels; the conductive tape on that connector will be re-heated. On all the frames in this stack (except the bottom end window and wire frame) we put new O-rings, because we observed some gas leakage. All the cathodes for the first package are ready except one; it has been tensioned and the next operation is to cut the flaps.
- Beni asked if the problems with the conductive tape show up at the same place on the connector due to uneven pressure. No, but Bill proposed to install a manometer at the cylinder to monitor that the pressure that comes from the compressor outside. Regarding resistor braking, we decided not to use lead bricks during the gluing of the PCB ring.
