Abstract :
The response of AGATA segmented HPGe detectors to gamma rays in the energy range 2–15 MeV was measured. The 15.1 MeV gamma rays were produced using the reaction d(11B,nγ)12C at Ebeam=19.1 MeV, while gamma rays between 2 and 9 MeV were produced using an Am–Be–Fe radioactive source. The energy resolution and linearity were studied and the energy-to-pulse-height conversion resulted to be linear within 0.05%.Experimental interaction multiplicity distributions are discussed and compared with the results of Geant4 simulations. It is shown that the application of gamma-ray tracking allows a suppression of background radiation caused by n-capture in Ge nuclei. Finally the Doppler correction for the 15.1 MeV gamma line, performed using the position information extracted with Pulse-shape analysis is discussed.
