Due to the Helium-3 crisis, alternatives to the standard neutron detection\ntechniques are becoming urgent. In addition, the instruments of the European\nSpallation Source (ESS) require advances in the state of the art of neutron\ndetection. The instruments need detectors with excellent neutron detection\nefficiency, high-rate capabilities and unprecedented spatial resolution. The\nMacromolecular Crystallography instrument (NMX) requires a position resolution\nin the order of 200 um over a wide angular range of incoming neutrons. Solid\nconverters in combination with Micro Pattern Gaseous Detectors (MPGDs) are\nproposed to meet the new requirements. Charged particles rising from the\nneutron capture have usually ranges larger than several millimetres in gas.\nThis is apparently in contrast with the requirements for the position\nresolution. In this paper, we present an analysis technique, new in the field\nof neutron detection, based on the Time Projection Chamber (TPC) concept. Using\na standard Single-GEM with the cathode coated with 10B4C, we extract the\nneutron interaction point with a resolution of better than sigma = 200 um.\n
