Implementation of a pixel tracker into simulation and comparison with data in a charm cross-section measuring test-beam. — •Matei Climescu, Fabian Hügging, Jens Janssen, Vadim Kostyukhin, Nikolaus Owtscharenko, David-Leon Pohl, and Markus Cristinziani — Physikalisches Institut, Universität Bonn

The SHiP collaboration plans a general purpose fixed-target experi- ment to search for hidden particles at a new beam-dump facility at the CERN SPS.

To estimate the total charm cross-section, including hadronic cascade production, in the final experiment, a dedicated measurement was performed. 400 GeV protons from the SPS interacted with a thick target, events were then recorded by a dedicated spectrometer consisting of emulsion plates, a pixel tracker, a magnetic field, scintillating fibers, drift tubes and RPCs. The pixel tracker was composed of 12 ATLAS IBL double chip modules, arranged in 6 planes, complementing the high spatial resolution of the emulsion detector with a high timing resolution.

The resulting data is compared to the simulation and will be used to tune it.
