Description
The Advanced GAmma Tracking Array, AGATA, is part of a new generation of highly segmented hyper-pure germanium (HPGe) gamma-ray detection arrays that are currently being developed for use at low-yield, high background radioactive ion beam facilities. AGATA aims to utilize gamma-ray tracking in order to add-back scattered gamma-rays that would be vetoed in arrays with a Compton suppression shield. Key to the GRT process is pulse shape analysis, (PSA), which is used to identify interactions within the germanium diodes to within a few milimetres.
An electric field simulation of the detector can also be utilized to calculate charge responses for the detector. In order to validate and test the accuracy of the pulse shapes produced by the simulation, coincident data taken with ancillary scintillation detectors is compared with a simulated database. With these techniques we aim to fully characterize the AGATA HPGe crystals.
Characterization of the charge response of the AGATA HPGe detectors is vital to build a database of pulse shapes corresponding to spatial locations within the detector. The results of characterization as well as a comparison of performance of two AGATA asymmetric detectors will be presented.
