Abstract :
The RD52 calorimeter measures the electromagnetic fraction of hadron showers in every event through simultaneous detection of the Cerenkov and scintillation light. This makes it possible to eliminate the main factor that prohibits precision energy measurements for hadrons. In Nov. 2012, the RD52 (DREAM) collaboration tested the performance of the new fiber calorimeter for the first time with high energy particles at the CERN SPS. The results presented here concern the performance characteristics for electrons and pions, as well as the identification of electrons in this longitudinally unsegmented calorimeter.
