Weighting potential distribution in bar-shaped (6x6x12 mm3) CdZnTeSe detector. 5-mm wide Frisch-grid band attached to below 1-mm from anode. It was easily calculated with FEM (finite element method) using Mathematica.
Left side (z=0) is cathode and right side (z=12) is anode. Sometimes (in scientific paper) the location of Frisch-grid is not properly discribed. The location of Frisch-grid should be anode side according to Ramo-theorem.
If you need Mathematica code (it is very simple), let me know.
