CCD-based X-ray area detector for time-resolved diffraction experiments.

Area of Science:

• * Physics and Biophysics
• * Materials Science
• * Medical Imaging

Background:

• * Traditional X-ray detectors often lack the speed required for dynamic experiments.
• * Capturing rapid biological and material processes necessitates high temporal resolution.

Purpose of the Study:

• * To develop a fast X-ray area detector for time-resolved experiments.
• * To achieve microsecond to millisecond time resolution in X-ray diffraction, scattering, and imaging.

Main Methods:

• * Utilized a fast framing camera with three Charge-Coupled Devices (CCDs).
• * Employed a prism to create identical images on the CCDs, enabling triple the frame rate.
• * Incorporated an X-ray image intensifier for X-ray to visible light conversion and tested with a high-resolution X-ray detector.

Main Results:

• * Achieved a frame rate of 291 frames per second.
• * Demonstrated the importance of short decay time phosphors for optimal high-speed performance.
• * Presented preliminary results from fiber diffraction on skeletal muscle and coronary angiography.

Conclusions:

• * The developed X-ray detector system successfully provides high-speed data acquisition.
• * The system is suitable for time-resolved X-ray diffraction, scattering, and imaging applications.
• * Further applications in biological and medical imaging are promising.
