Abstract:
In the years between 2000 and 2002 several pre-series and series modules of the
ATLAS EM barrel and end-cap calorimeter were exposed to electron, photon and pion beams. The performance of the calorimeter with respect to its finely segmented
first sampling has been studied. The polar angle resolution has been found to be
in the range 50 − 60 (mrad)/sqrt(E) (GeV). The π0 rejection has been measured to
be about 3.5 for 90% photon selection efficiency at pT = 50 GeV/c. e-π separation
studies have indicated that a pion fake rate of (0.07-0.5)% can be achieved while
maintaining 90% electron identification efficiency for energies up to 40 GeV.
