Description
AMS-02 is an astroparticle experiment that will operate on board of the ISS
for a period of about 3 years. The main scientific goals of the experiment are
the search for antimatter and dark matter and the study of gamma rays. In
AMS-02 the Electromagnetic Calorimeter (ECAL) plays a key role for its high
capability to measure e +, e− and gamma spectra and to discriminate
electromagnetic showers from hadronic cascades in the energy range from
few GeV up to one TeV. The detector has been designed following stringent
requirements such as very high mechanical and thermal stability, low
weight and power consuption, radiation hardness. After a full scale ECAL
protype had successfully passed functional and space qualification tests, the
detector flight model was assembled and tested at CERN in October 2006
using electrons and protons beams. Results of the measurements of the
ECAL parameters and performances such as linearty, energy and angular
resolution, are presented.
