Standalone tracking in the ALICE Transition Radiation Detector — •Markus Fasel and Alexandru Bercuci — GSI, Planckstr. 1, 64291 Darmstadt

We present a study of the reconstruction algorithms for the ALICE Transition Radiation Detector (TRD) using data measured at the CERN PS with a complete supermodule of TRD. We focus on the TRD standalone tracking algorithm, which is the backbone of track reconstruction and has an important role in TRD offline analysis as well as for the processing in the ALICE High Level Trigger. The efficiency, robustness and speed of the standalone tracker are prime requirements for the algorithm. Track reconstruction is essential for the particle identification with TRD, as well as for the algorithms for detector calibration. Results of the tracking obtained using measured data are presented.
