10. Detector Characterisation Offset of the horizontal segmentation line in rings 2 and 3, due to the electron and hole drift profile being influenced by the fast/slow axis orientations. The scan of detector C001 revealed a 12° offset toward segment B from that specified by the AGATA collaboration. Implication need to characterise to determine true axis orientation
