semiconductor-based radiation detector

The dimension of detector is 12x12x12 mm3. Applied 1 V in z=12 plane at 5.5 Here is the weighting potential in density plot, equipotential line (green), and electric field vectors (black). It is weight potential in pixellated detector along z-axis at x = 6 mm and y = 6 mm. The shape of weighting potential is same with that of Frisch-grid and hemi-spherical detector. Now you can understand ..

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 sho..
