Description
The Transition Radiation Detector (TRD) of ALICE at the CERN-LHC
is designed to provide electron identification and an online trigger
on high-pt tracks of electron candidates. It consists of 6 layers of
drift chambers, covering a pseudo-rapidity range of |eta| < 0.9. In
its current configuration, 10 out of 18 sectors in azimuth are
installed. The completion of the detector is planned for the LHC shut
down in 2013/14.
We will give an overview on the setup and working principle of the TRD
and summarize experiences from the commissioning phase. Results on the
achieved detector performance, such as the pion suppression factors
and the tracking resolution, will be discussed. Also, we will report
on online and offline calibration procedures and their performance.
