Development of Scintillation Neutron Detector using Wavelength-shifting Fiber Technology
hamon(2017)
Abstract
Development of scintillation neutron detectors using wavelength-shifting fiber (WLSF) technology at J-PARC MLF is briefly reviewed. The neutron-detecting head of this type detector comprises neutron-sensitive scintillator screens and WLSFs for light read out. The light collection using WLSFs enables us to design a detector with great flexibility. Detector specifications such as pixel size, spatial resolution, and neutron-sensitive area can be optimized to requirements in specific applications. We have intensively developed these detectors since 2005. A large number of detector modules have been produced and delivered to the neutron scattering instruments in the MLF. In this paper the design of SENJU detector is presented in detail together with recent development effort for detector technology alternative to helium-3 gas detectors.
