The Central Straw Tube Tracker for PANDA — •Marius C. Mertens — Forschungszentrum Jülich GmbH

The PANDA experiment at the future Facility for Antiproton and Ion Research (FAIR) will investigate physics in the open charm energy region using an antiproton beam and a fixed hydrogen target.

A significant part of PANDA's physics program will require the reconstruction of rare channels. Consequently, the experiment is optimized for high luminosities with a quasi-continuous beam, thus the detector must be able to process high particle rates in a continuous manner.

The central tracker of PANDA has the task to precisely measure the traversing particles' tracks as well as their energy loss in order to also contribute to the particle identification information. A Straw Tube Tracker (STT) is under development for PANDA. The detector concept has proven to be a robust device for the track reconstruction already in the COSY-TOF experiment. In PANDA, there will be higher rates and the additional energy loss information which require new readout electronics which is being tested and optimized.

After introducing the design of the PANDA STT, we will present the prototype setup and our most recent results from test measurements.
