Abstract: The uniformity of PbWO4 crystals grown by the Bridgman method was investigated by the measurements of transmission and light yield for full-size crystals and the different parts of ingot.The results show that the crystal quality in the later growth period is the main factor mfluencing the uniformity, and a favorable geometric shape can improve the uniformity of PbWO4.

Key words: PbWO4 crystals, transmission spectra, light yield, uniformity
