s393/land02 workshop 2011

In the s393 experiment, the momentum distribution of the knocked-out protons is of crucial importance. Determination of this distribution in the current setup depends on the trajectory of the protons after the ALADIN magnet. For this reason, two drift chambers are used to measure the position of the knocked-out protons. In this presentation, I will report on the calibration of the drift chambers as well as the proton track reconstruction.
