3D position sensitivity of a highly segmented Ge detector
2005 (English)In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, Vol. 550, no 02-jan, 278-291 p.Article in journal (Refereed) Published
The 3D position resolution of a planar HPGe detector with a 25-fold segmented cathode contact has been studied. The measurements were performed with a collimated Cs-137 gamma-ray pencil beam and a coincidence scattering technique that selects single interaction events at well-defined irradiation points. The gamma rays scattered at 90 degrees, depositing 374 keV energy in the detector, were registered and the pulse shapes from the irradiated segment and three neighboring segments were analyzed. The resulting average 3D position sensitivity for single gamma-ray interactions is estimated at 0.4 mm.
