AGATA: performance of $$\gamma $$-ray tracking and associated algorithms

Abstract

AGATA is a modern $$\gamma $$ -ray spectrometer for in-beam nuclear structure studies, based on $$\gamma $$ -ray tracking. Since more than a decade, it has been operated performing experimental physics campaigns in different international laboratories (LNL, GSI, GANIL). This paper reviews the obtained results concerning the performances of $$\gamma $$ -ray tracking in AGATA and associated algorithms. We discuss $$\gamma $$ -ray tracking and algorithms developed for AGATA. Then, we present performance results in terms of efficiency and peak-to-total for AGATA. The importance of the high effective angular resolution of $$\gamma $$ -ray tracking arrays is emphasised, e.g. with respect to Doppler correction. Finally, we briefly touch upon the subject of $$\gamma $$ -ray imaging and its connection to $$\gamma $$ -ray tracking.
