摘要：

As a part of the INTEGRAL (International Gamma-Ray Astrophysical Laboratory) project, CsI(Tl) scintillation elements with a cross-sectional area of 1cm2, and between 1 and 6 cm in length have been developed to form the basis of the imager detector plane. The crystal preparation and wrapping, crystal geometry, optical coupling and matching to the photodiode have all been optimised in order to maximise the light output from the crystal, and hence produce the lowest energy threshold and best spectral resolution for any given readout electronics. Energy resolutions of 18% at 122 keV and 5.5% at 662 keV have been obtained using a 1cm3 crystal on a 10x10mm photodiode. With standard laboratory electronics, a low energy threshold of approximately 35 keV has been obtained.
