A new instrument system with the capability of secondary-particle discrimination (InSPaD) was studied for the development of two-dimensional (2D) neutron detectors (NDs) filled with helium-3 gas and with high spatial resolution. The InSPaD can discriminate between tracks of a proton and a triton created in the nuclear reaction 3He(n,p)T by simply setting the level of the discriminator appropriately in each signal channel, and the system exhibits a high spatial resolution, high counting rate, low background, and stability. The InSPaD identifies the tracks of a proton and a triton on the basis of the length of the tracks, identifies the secondary particles, and calculates the incident positions of neutrons accurately in real time. Simulations of the 2D ND equipped with InSPaD revealed spatial resolutions of 0.46 mm in full width at half maximum for a 10% mixture of C2H6 with helium-3 at 0.3 MPa, and of 0.52 mm for a 20% mixture of argon with helium-3 at 0.5 MPa. The simulated results of the ranges of secondary particles and the pulse-height distribution along the track agreed well with the experimental results of neutron detection using a microstrip gas chamber, thus indicating the feasibility of the InSPaD.
