Characterisation of an asymmetric AGATA detector
2009
The Advanced GAmma Tracking Array (AGATA) is a next-generation gamma-ray spectrometer for nuclear
physics being developed as part of a Europe-wide collaboration. AGATA aims to vastly improve upon the
sensitivity of today's arrays by removing the BGO shields used to suppress the Compton background and
instead, tracking gamma rays through a complete 4π shell of Germanium using Gamma Ray Tracking (GRT).
In order to facilitate this, Pulse Shape Analysis (PSA) must be used to accurately locate the position of each
gamma-ray interaction within each detector.
The preferred approach to PSA relies on the generation of a database of typical pulse shapes produced by
interactions at each position on a grid throughout the detector. This paper details current progress at the
University of Liverpool toward validating the electric field simulation, which will be used to generate the pulse
shape database, with experimental data from an asymmetric AGATA detector. The field simulation is discussed
and some comparisons are made between this and a two dimensional raster scan of the detector with a highly
collimated source.
