  The FAIR facility is an international accelerator centre for research with
ion and antiproton beams. It is being built at Darmstadt, Germany as an
extension to the current GSI research institute. One major part of the facility
will be the Super-FRS separator, which will be include in phase one of the
project construction. The NUSTAR experiments will benefit from the Super-FRS,
which will deliver an unprecedented range of radioactive ion beams (RIB). These
experiments will use beams of different energies and characteristics in three
different branches; the high-energy which utilizes the RIB at relativistic
energies 300-1500 MeV /u as created in the production process, the low energy
branch aims to use beams in the range of 0-150 MeV/u whereas the ring branch
will cool and store beams in the NESR ring. The main tasks for the Super-FRS
beam diagnostics chambers will be for the set up and adjustment of the
separator as well as to provide tracking and event-by-event particle
identification. The Helsinki Institute of Physics, the Comenius University, and
the Detector Laboratory and Experimental electronics at GSI are in a joint R&D
phase of a GEM-TPC detector which could satisfy the requirements of such
diagnostics and tracking chambers in terms of tracking efficiency, space
resolution, count rate capability and momenta resolution. The current status of
the first prototype and the preliminary results from the test beam campaign
S417 using the n-Xyter chips mounted on GEMEX cards will be shown.
