Characterization of an AGATA HPGe detector

Carl Unsworth, University of Liverpool, United Kingdom
Building 6008 Conference Room

AGATA, The Advanced GAmma Tracking Array, is a gamma-ray spectrometer being developed by a large European collaboration. The aim is to build a complete 4pi shell of HPGe detectors for use in nuclear physics experiments at the latest radioactive ion beam facilities. The completed array will provide unprecedented resolving power by employing gamma-ray tracking (GRT) to reconstruct the incident energy of Compton scattered gamma rays. Successful GRT requires precise knowledge of interaction positions which will be achieved by analysis of the detector signal shape. Current work in the Liverpool detector lab has been aimed at characterizing the position response of AGATA detectors and understanding the effect of electronic components on the signal shape.
