ELI-NP is an European Research Infrastructure that will provide a monochromatic,high brilliance gamma beam with tunable energy up to 19.5 MeV. The time structure of the beamconsists of 32 high intensity gamma bunches separated by a time interval of 16 ns and deliveredat a repetition rate of 100 Hz. In order to match such unprecedented beam specifications, specificdevices and techniques have been developed to measure and monitor the beam parameters duringthe commissioning and the operational phase. This paper presents an overview of the gammabeam characterization system, with particular focus on a new-concept sampling calorimeter madeof silicon detectors and polyethylene absorbers.
