Production

- Started stacking again the package; we have already installed the first cell and the first cathode for 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.
