Abstract:

This memorandum presents the results of calculations
on the following topics:
- impact of the cathode flatness on the cathode readout resolution;
- the cathode foil tension and ways to measure it;
- the stresses in the foil with a round hole at the center;
- the impact of the hole in the cathode foils on the background rates.
