Implementation of a Forward Tracking System for PANDA* — •Martin Johannes Galuska1, Radosław Karabowicz2, Wolfgang Kühn1, Jens Sören Lange1, and Björn Spruck1 — 1II. Physik. Inst., JLU Gießen — 2GSI
The PANDA experiment at the future FAIR facility at GSI Darmstadt is planned to start operation in 2017 utilizing antiproton beams with beam momentum resolutions of Δ p/p ≤ 2 · 10−5. In particular, PANDA is well fit to perform resonance scans of exclusively produced charmonium(-like) states and thus provide absolute measurements of resonance widths.
In this poster we will report on the current status of the implementation of a forward tracking system for the PANDA detector. The forward tracking is of particular importance as PANDA is a fixed target experiment, and thus in charmonium production a large fraction of final state particles will be boosted toward forward angles. The key challenges for the implementation of a forward track finder and track fitter arise from a complicated magnetic field map as PANDA is comprised of a barrel part with a solenoid field of Bz=2 T and a forward detector part with a dipole field of B · L =2 Tm. The interference of the magnetic fields has to be taken into account. Furthermore, the forward tracking requires a matching of hits from numerous subdetectors (e.g. axial and stereo straw tubes, straw tube planes perpendicular to the beam axis, GEM tracker, etc.) with high accuracy.
