    "abstract": "We report on the performance of a micro-TPC with a micro pixel\nchamber($\\mu$-PIC) readout for a time-resolved neutron position-sensitive\ndetector(PSD). Three-dimensional tracks and the Bragg curves of protons with\nenergies of around 1 MeV were clearly detected by the micro-TPC. More than 95%\nof gamma-rays of 511 keV were found to be discriminated by simple analysis.\nSimulation studies showed that the total track length of proton and triton\nemitted from the $\\rm {}^{3}He$(n,p(573 keV))$\\rm {}^{3}H(191 keV)$ reaction is\nabout 1.2 cm, and that both particles have large energy losses ($\\rm \u003e 200\nkeV/cm$) in 1 atm Ar+$\\rm C_{2}H_{6}(10%)$+${}^{3}$He($\u003c 1%$). These values\nsuit the current performance of the micro-TPC, and we conclude that a\ntime-resolved neutron PSD with spatial resolution of sub-millimeters shall be\ndeveloped as an application of the micro-TPC.",
