N1 - Funding Information:
We thank CERN for making particle beams available to our experiments in the H8 beam. We gratefully acknowledge Eileen Hahn and Erik Ramberg of Fermilab who took care of the aluminization of the Cherenkov fibers used in one of the copper modules. This study was carried out with financial support of the United States Department of Energy , under contract DE-FG02-12ER41783 , and by Italy's Istituto Nazionale di Fisica Nucleare and Ministero dell'Istruzione, dell'Università e della Ricerca.

N2 - The RD52 dual-readout calorimeter is a longitudinally unsegmented instrument intended for the detection of both electromagnetically and hadronically interacting particles with unprecedented precision. In this paper, the identification of the showering particles and, in particular, the identification of electrons and γs with this instrument are investigated. The techniques used for this purpose include differences in the shower development observed with scintillation light and Cherenkov radiation, the radial shower profile of the particles and the time structure (including the starting point) of the calorimeter signals. It turns out that, at 60 GeV, electrons can be correctly identified in 99.8% of the cases, by means of criteria that eliminate 99.8% of the hadrons.
