The surface resistance of the internal coating of pipes is an important characteristic which could indicate zones with the corrosion or leakages. In the particular case of particle accelerators, this parameter becomes even more important for the performance. We designed a scanning cell for the monitoring of the surface resistance along the whole pipe length. We show an example of the geometry optimization of the scanning cell for the octagonal shaped beam screen. Taking into account a TE011 operating mode we determine the geometry of the cell from the point of view of sensitivity and the resonant frequency of the operation.
