Abstract

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