A systematic study is made of the characteristics for neutron detection of boron- and lithium-containing glass scintillators. The results of measurements of the optical transmission, the pulse-height distribution, and the time dependence of scintillation intensity are presented. A careful study of the pulse-height distributions for thermal neutrons shows that a major part of the width of the distributions can be accounted for in terms of well-understood statistical fluctuations. Problems associated with the application of the scintillators are considered, with special emphasis on application to time-of-flight neutron spectroscopy. As part of these considerations, a Monte Carlo calculation is performed to obtain a complete understanding of the time uncertainties involved in the capture of neutrons in the scintillators. It is concluded that the lithium glass in an excellent detector of neutrons when large uncertainties in time ( > 0.3 >sec) can be tolerated, the boron glass excels when intermediate accuracy (≈ 30 nsec) in timing is required, but neither kind of glass is suitable for most experiments that require fast timing.
