Abstract

Test-beam studies of the ATLAS Transition Radiation Tracker (TRT) straw tube performance in terms of electron-pion separation using a ti me-over-threshold method are described. The test-beam data are compared with Monte Carlo simulations of charged particles passing through the straw tubes of the TRT. For energies below 10 GeV, the time-over-threshold method combined withthe standard transition-radiation cluster-counting technique significantlyimproves the electron-pion separation in the TRT. The use of the time-over-threshold information also provides some kaon-pion separation. thereby significantly enhancing the B-physics capabilities of the ATLAS detector.
