Recent developments in neutron detection

Developments in neutron detection technology during the past three years are reviewed with special emphasis on those technologies with known or possible application to safety, security, or industrial development. The technologies discussed include track detectors, image plates, activation detectors, bubble detectors, proton recoil instruments, time-of-flight instruments, moderating detectors, proportional counters, semiconductor detectors, and scintillation detectors. The review concentrates on advances in detection technology rather than on the use of existing methods for applications. For the purposes of this review, neutron spectrometry is considered to be a subset of the general area of neutron detection.
