Abstract

The performance of the Advanced GAmma Tracking Array (AGATA) at GANIL is discussed, on the basis of the analysis of source and in-beam data taken with up to 30 segmented crystals. Data processing is described in detail. The performance of individual detectors are shown. The efficiency of the individual detectors as well as the efficiency after γ-ray tracking are discussed. Recent developments of γ-ray tracking are also presented. The experimentally achieved peak-to-total is compared with simulations showing the impact of back-scattered γ rays on the peak-to-total in a γ-ray tracking array. An estimate of the achieved position resolution using the Doppler broadening of in-beam data is also given. Angular correlations from source... (More)

The experimentally achieved peak-to-total is compared with simulations showing the impact of back-scattered γ rays on the peak-to-total in a γ-ray tracking array. An estimate of the achieved position resolution using the Doppler broadening of in-beam data is also given. Angular correlations from source measurements are shown together with different methods to take into account the effects of γ-ray tracking on the normalization of the angular correlations.
