Study of electron identification in a few GeV region by an emulsion cloud chamber

We have performed an experimental study of electron identification using an emulsion cloud chamber detector with electron-enriched pi /sup -/ beams at 2 and 4 GeV/c produced by the proton synchrotron source at CERN. This study shows that the efficiency of electron identification is about 90% with li...

Sumario:We have performed an experimental study of electron identification using an emulsion cloud chamber detector with electron-enriched pi /sup -/ beams at 2 and 4 GeV/c produced by the proton synchrotron source at CERN. This study shows that the efficiency of electron identification is about 90% with little (6%) contamination from pions. These results are in agreement with those obtained using a Cherenkov counter and are reproduced well by the simulation. (4 refs) .
