Super-FRS GEM-TPC Prototype Development Based on n-Xyter Asic for the FAIR Facility

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.
