Abstract
The signals from lead tungstate crystals are studied as a function of temperature. Over the range from 13 to 45 degrees C, the total light output decreases by about a factor of two. This effect only concerns the scintillation component, so that the relative contribution of Cherenkov light to the signals increases with the same factor. The decay time of the scintillation component is observed to decrease as well. (C) 2008 Elsevier B.V.
