Abstract
We have measured the temperature dependence of parametric x-ray radiat ion (PXR) from a Si single crystal bombarded by 900-MeV electrons. The radiation intensity is appreciably enhanced when the crystal is coole d to liquid-nitrogen temperature as compared with the case for room te mperature. The enhancement factors are larger for the higher-order ref lections and are quantitatively consistent with the assumption that th e PXR intensities are proportional to the squared Debye-Waller factor.
