Improved x-ray converters for CCD-based crystallography detectors

摘要: We are developing a large area structured CsI(Tl) imaging sensor for macro-molecular x-ray crystallography use with both intense synchrotron sources and rotating-anode laboratory x- ray sources. The scintillator is grown on specially designed optical substrate. Our work has produced sensors up to 70% more light output, orders of magnitude faster decay time response, greater spatial resolution (15% MTF at 20 lp/mm) than Gd2O2S screens currently used in CCD-based detectors biological structure determination. These advances performance will address some the limitations existing detector technology. Performance measurements prototype presented. With these new development larger millisecond data acquisition capabilities high resolution, suitable applications be possible.© (1995) COPYRIGHT SPIE--The International Society Optical Engineering.
