Abstract
The light output and its non-uniformity of nine crystal samples with 40 mm×40 mm×300 mm dimensions were tested. Different wrapping materials and methods were used, and the optical readout method to obtain high light output and good uniformity was found. The non-uniformity of all tested CsI(Tl) samples is less than 7%, and some is even about 2%. The factors causing non-uniformity of light output are discussed.
