Other Detectors

This chapter describes other detectors used in scattering facilities or under development. These other detectors include semiconductor-based neutron beam monitors and detectors, vacuum-based neutron detectors, image plates, charge-coupled devices (CCDs), and pixelated detectors. This chapter presents also the midterm plans to develop detector-critical parameters for future instrument needs by 2030. In addition to the gaseous and wavelength shifting fiberWavelength shifting fiber (WLSF) detectors along with the Anger camerasAnger cameras described in the previous chapters, many other neutron detectors are either being used in neutron scatteringNeutron scattering facilities or are being developed by research and development groups for many critical applications with gaps or unmet needs. The current focus is on the development of neutron detectors exhibiting high detection efficiencyEfficiency, a high counting rateCounting rates, and position resolutionPosition resolutions at a reduced cost. Improvements in these detector characteristics will enable enhanced materials science and lead to more discoveries as novel detector technologies and instrumentation become available. Developing a complex neutron detection system is a lengthy process given the design and fabrication time for each component, the effort of integration, and the time needed for characterization design and deployment of these cutting-edge detectors for current and future instruments.

This chapter finally presents the midterm plans to develop detector-critical parameters for future instrument needs by 2030.
