Potential of RPCs for tracking
  We have demonstrated that small gap (0.1 to 0.4 mm) RPCs made of low resistivity materials (less than 1E8 Ohm.cm) can operate at counting rates of up to 1E5 Hz/mm2 with position resolutions better than 50 micrometer. Results of preliminary tests allow us to suggest a possible application of this new type of RPC for tracking.
