Summary

We present results of beam tests performed in 2007 as part of the DREAM project.
Previously, we already demonstrated that Lead Tungstate signals contain both
scintillation and Cherenkov components. In order to further assess and evaluate the
relative contribution of the Cherenkov component, we performed measurements at
different temperatures, ranging from 13°C to
45°C. Only the scintillation component was affected by the temperature change. Over
this temperature range, the total light yield was measured to decrease by a factor of
2, while the relative Cherenkov contribution to the signals increased by the same
factor. We also studied the decay time of the scintillation process and observed it
to decrease as well.
