Popis: | The electromagnetic Calorimeter (ECAL) of the AMS-02 experiment is a fine grained lead-scintillating fibers sampling calorimeter that allows for a precise 3-dimensional imaging of the longitudinal and lateral developement of electromagnetic showers. With a total thickness of 17 X 0 , electromagnetic showers are well contained and the energy resolution is 2% up to 1 TeV. ECAL provides a high discrimination between electromagnetic and hadronic showers; furthermore, together with the rest of the AMS-02 detector, it is able to identify the subdominant ( ≃ 10 − 6 ) photon flux from GeV up to TeV energies. Thanks to its high granularity ECAL has an excellent pointing capability ( 0 . 5 o at high energies) that offers an unusual possibility of drawing sky maps with the calorimeter standalone. |
