Motivated by measuringγ-rays with CsI crystals, the performance of the CsI(Tl) crystal with the shape as shown in Fig. 1 has been tested. The crystal was grown and machined by IMP crystal group. Firstly, different wrapping materials have been investigated. The tested wrapping materials are Teflon, Tyvek (1056D from Dupont) and ESR (from 3M). During the test, the crystal was
