Abstract
Weighting potentials in the metallized and non-metallized regions at the su rface of CZT strip and coplanar-grid detectors are measured by scanning an a source or a laser spot across the segmented face and recording the charge induced on various electrodes after the electron collection time. These me asurements are found to be in good agrement with the solution of Laplace eq uation with mixed boundary conditions.
