Reconstruction performance of the ALICE Transition Radiation Detector — •Markus Fasel^1,2, Anton Andronic¹, and Bercuci Alexandru¹ — ¹GSI, Planckstr. 1, 64291 Darmstadt — ²Technische Universität Darmstadt, Hochschulstraße 12, 64289 Darmstadt

The Transition Radiation Detector(TRD) is an important component of the ALICE experiment at LHC. With tracking and particle identification capabilities, the TRD will contribute significantly to the measurement of quarkonia, open heavy flavours, and jets. During the commissioning of the LHC in the fall of 2008 cosmic-ray data were taken with the ALICE setup including four supermodules of the Transition Radiation Detector. We present the results on the reconstruction performance of the TRD obtained with cosmic-rays. We focus on the position resolution and the accuracy of matching with the Time Projection Chamber.
