A glass scintillator which can be used as one of the main components of a slow-neutron time-of-flight spectrometer was developed. Sodium aluminoborate glass containing 73 mole% B/sub 2/O/sub 3/ and 8.0 mole% Ce was melted under highly reducing conditions in a series of ceriumactivated very high boron- containing glasses. The glass is water white with very high light transmittance for wave lengths greater than 3800 A. It has a neutron-detection efficiency which is 25 to 30% greater than any other known glass scintillator in the energy range 10/sup 2/ to 10/sup 4/ ev, and is considerably better than any other type of detector. It was found that the neutron pulse height increases with increasing cerium content up to a maximum and then decreases with further increases in the cerium content. The molar content of cerium required to obtain a maximum pulse height for each B/sub 2/O/sub 3/ concentration increases linearly with the increase in the B/sub 2/O/sub 3/ content. However, the maximum pulse height decreases gradually with the B/sub 2/O/sub 3/ content from 17.0 arbitrary units at 54.5 mole% to 6.7 at 73.4 mole%. This lower pulse height is still considerably above the photomultiplier noise at room temperature. (auth)
