The ALICE Transition Radiation Detector Design and Performance
detector principle and overview results from testbeam measurements
dE/dx transition radiation electron/pion separation position and angular resolution
performance of electronics status of the project
Johannes P. Wessels, Universität Münster for the ALICE TRD Collaboration
readout with MCMs Ar/CO2 (85/15) Vanode = 1400 V vd = 2.6 cm/s
Summary
pion rejection and tracking capability fulfill specs quantitative understanding of
dE/dx, position and angular resolutionTR production & absorption
promising results of PASA and digital ASIC evaluation
good trigger capability for high pt charged particles
starting series production now aim to be ready for first events in 2007 physics performance report http://alice.web.cern.ch/ALICE/ppr
