Tracking of charged particles using an FE-I4B pixel telescope and moving emulsion films — •Nikolaus Owtscharenko1, Vadim Kostyukhin1,2, Matei Climescu1,3, Fabian Hügging1, Jens Janssen1, David-Leon Pohl1, and Markus Cristinziani1 — 1Physikalisches Institut, Universität Bonn — 2now at Departement of Physics and Astronomy, University of Sheffield — 3now at Institut für Physik, Universität Mainz
The SHiP collaboration plans a general purpose fixed-target experiment to search for hidden particles at a new beam-dump facility at the CERN SPS.
To estimate the total charm cross-section in the final experiment, which includes hadronic cascade production, a dedicated measurement was performed in summer of 2018. 15 · 105 Protons at 400 GeV from the SPS interact with a thick multilayer target, interleaved with tracking emulsion films.
A 6 plane telescope made of ATLAS IBL double-chip modules was positioned behind this target and complements the high spatial resolution of emulsion with a high timing resolution.
Telescope efficiency, comparison of results to simulation and reconstruction of first events are presented.
