Description

We will present our studies of the performance of the reconstruction in the ALICE Time projection chamber (TPC). The reconstruction algorithm in question is based on the Kalman filter. The performance is characterized by the resolution in the position, angle and momenta as a function of particle properties (momentum, position). The resulting momentum parametrization is compared with the MonteCarlo simulation, which allows to disectangle the material budget and systematic effects influences. The presented studies were performed on the cosmic data.
