| Abstract | Full-size (22x22x180 mm sup 3) ALICE crystals were delivered by 'North Crystals' company, Apatity, Russia. These crystals were tested with test benches, specially built for measurements of the crystals optical transmission and light yield. Beam-test results of different sets of 3x3 matrices with Hamamatsu APD light readout are presented. Data were taken at electron momenta from 600 MeV/c up to 10 GeV/c. Energy resolution and linearity curves are measured. The tests were carried out at the CERN PS and SPS secondary beam-lines. |
