Paper Abstract

We are developing a large area structured CsI(Tl) imaging sensor for macro-molecular x-ray crystallography for use with both intense synchrotron sources and rotating-anode laboratory x- ray sources. The CsI(Tl) scintillator is grown on a specially designed optical substrate. Our work has produced x-ray sensors with up to 70% more light output, orders of magnitude faster decay time response, and greater spatial resolution (15% MTF at 20 lp/mm) than Gd2O2S screens currently used in CCD-based detectors for biological structure determination. These advances in performance will address some of the limitations of existing area detector technology. Performance measurements for a prototype CsI(Tl) scintillator are presented. With these new sensors the development of larger area x-ray crystallography detectors with millisecond data acquisition capabilities and high spatial resolution, suitable for synchrotron applications will be possible.
