Performance of prototype neutron detectors for Large Acceptance Multi-Purpose Spectrometer at RAON
2019
Abstract The performance of the prototype modules of neutron detectors for the Large Acceptance Multi-Purpose Spectrometer (LAMPS) was investigated, using cosmic
muonsand neutron beams at 65 and 392 MeV, provided by the Research Center for
Nuclear Physics(RCNP). The timing and position resolutions were estimated using cosmic
muonsas 309 ps and 4.8 cm, respectively. The energy resolution depended on the incident energy of neutrons: 1.3% at 65 MeV and 3.1% at 392 MeV. The
neutron-detectionefficiency also showed weak energy dependence as it decreased from (9.0 ± 1.6)% at 65 MeV to (6.3 ± 1.0)% at 392 MeV.
