Resolution of a Position-sensitive Neutron Detector Based on the Tilted-wire Position Reading Method
Position resolution of a position-sensitive proportional counter developed for neutron detection has been studied. The counter is based on the tilted-wire position reading method and consists of a pair of position sensing wires being extended in parallel each other but tilted against the anode wire....

| description | Position resolution of a position-sensitive proportional counter developed for neutron detection has been studied. The counter is based on the tilted-wire position reading method and consists of a pair of position sensing wires being extended in parallel each other but tilted against the anode wire. Natural boron and boron nitride in solid phase and of about 1 mm width are employed as neutron converters. The counting gas is PR gas and the pressure of the gas is varied from 1.00 to 1.44-atm. The two-dimensional spectra of position vs. energy for the emitted charged particles are observed and boron-related neutron events can be clearly identified. The position spectra are deduced from the two-dimensional data, and the effect of gas pressure and particle energy on the position resolution is discussed. The position resolution of about 2 mm full width at half maximum (FWHM) is obtained at 1.44 atm for low-energy events. |
