Correlation of Beam Electron and LED Signal Losses under Irradiation and Long-term Recovery of Lead Tungstate Crystals
V. A. Batarin, J. Butler, A. M. Davidenko +26
Radiation damage in lead tungstate crystals reduces their transparency. The calibration that relates the amount of light detected in such crystals to incident energy of photons or…
Study of Possible Scintillation Mechanism Damage in PbWO4 Crystals After Pion Irradiation
V. A. Batarin, J. Butler, T. Y. Chen +28
We employed two independent methods to study possible damage to the scintillation mechanism in lead tungstate crystals due to irradiation by a 34 GeV pion beam. First, 10 crystals…
Comparison of Radiation Damage in Lead Tungstate Crystals under Pion and Gamma Irradiation
V. Batarin, J. Butler, T. Chen +28
Studies of the radiation hardness of lead tungstate crystals produced by the Bogoroditsk Techno-Chemical Plant in Russia and the Shanghai Institute of Ceramics in China have been c…
LED Monitoring System for the BTeV Lead Tungstate Crystal Calorimeter Prototype
V. Batarin, J. Butler, A. Davidenko +28
We report on the performance of a monitoring system for a prototype calorimeter for the BTeV experiment that uses Lead Tungstate crystals coupled with photomultiplier tubes. The te…
