Correlation between Light Response Uniformity and Longitudinal Transmission in 600 mm BGO Crystals

Abstract:

Based on the need of calorimeter for dark matter search in China, 600 mm BGO crystals were investigated on longitudinal transmission and light response uniformity of crystal. In the analysis of the data obtained, a strong correlation between the crystal light response uniformity and their longitudinal transmission in the range 435 nm has been noticed. As a consequence, the transmission measurement alone can be used to help classification of crystal and identify crystals requiring uniformization. In the following the outcome of this analysis and the results that can be achieved will be discussed.
