Abstract

We show that electromagnetic and hadronic showers can be distinguished through differences in the time structure of the calorimeter signals. These differences occur at the level of 5-10 ns. It is experimentally observed that with a detector that is sufficiently fast, i.e. the scintillating fibre calorimeter developed in the framework of the LAA project at CERN, e/π separation can be achieved at the 1% level, independent of any knowledge of the shower profile.
