Abstract
Searches for weakly interacting massive particles (WIMP) can be based on th e detection of nuclear recoil energy in CsI(Tl) crystals. We demonstrate th at low-energy gamma rays down to a few keV are detected with CsI(Tl) crysta l detector. A clear peak at 6 keV is observed using an X-ray source. Good e nergy resolution and linearity have been achieved down to the X-ray region. In addition, we also show that alpha particles and gamma rays can be clear ly separated using the different time characteristics of the crystal. (C) 2 001 Elsevier Science B.V. All rights reserved.
