Electron identification performance with ALICE TRD prototypes

Abstract

We present the electron/pion identification performance measured with prototypes for ALICE TRD. Measured spectra of energy deposit of pions and electrons as well as their average values are presented and compared to calculations. Various radiators are investigated over the momentum range of 1 to 6 GeV/c. The time signature of TR is exploited in a bidimensional likelihood mothod.

Presented at the conference "TRDs for the 3rd millenium", Bari, Italy, Sept. 4-7 2003. To appear in Nucl.Instrum.Meth. A. (4 pages, 6 figures)
