Inter-Strip Interpolation Measurements in a High-Purity Germanium Double-Sided Strip Detector

One fundamental design issue in the HPGe double-sided strip detector is the gap between strips, which makes up 1/6 of the 3 mm strip pitch in the UM HPGe strip detector. When an interaction occurs in the gap between strips, charge-carriers from the resulting charge cloud may be split between adjacent strips. Additionally, up to 6% of the carriers may be lost. Furthermore, use of the signals obtained for interactions that occur in gaps is complicated by their sensitivity to the change in charge cloud geometries and the difficulty of distinguishing single interactions from multiple close interactions.
