New developments in Thin Gap Chamber (TGC) detectors to provide fast trigger information and high precision muon tracking under sLHC conditions are presented. The modified detectors are shown to stand a high total irradiation dose equivalent to 6 C/cm of wire, without showing any deterioration in their performance. Two large (1.2×0.8 m2) prototypes containing four gaps, each gap providing pad, strip and wire readout, with a total thickness of 50 mm, have been constructed. Their local spatial resolution has been measured in a 100 GeV/c muon test beam at CERN. At perpendicular incidence angle, a single gap position resolution of better than 60μm has been obtained. For an incidence angle of 20° a resolution of less than 100μm was achieved. TGC prototypes were also tested under a flux of 105 Hz/cm2 of 5.5–6.5 MeV neutrons, showing a high efficiency for the detection of cosmic muons.
