Development of micro-PIC as a time-resolved X-ray area detector.

Area of Science:

• Materials Science
• Crystallography
• Particle Detectors

Background:

• X-ray diffraction (XRD) is a crucial technique for determining crystal structures.
• Traditional XRD methods can be time-consuming and require specialized equipment.
• Advancements in detector technology are needed for faster and more efficient data acquisition.

Purpose of the Study:

• To report the application and performance of a two-dimensional micro-pixel gas chamber (micro-PIC) for X-ray diffraction.
• To evaluate the micro-PIC's capability for real-time X-ray imaging and data collection.

Main Methods:

• Development of a micro-PIC with a 10 cm x 10 cm detection area and a fast-readout system.
• Utilizing the timing information from the micro-PIC for continuous rotation X-ray diffraction measurements.
• Analysis of diffraction data from a 400 microm-diameter spherical organic crystal of Ylid (C(11)H(10)O(2)S).

Main Results:

• Successful acquisition of X-ray diffraction spots up to 2theta of 49 degrees.
• Achieved good internal agreement factors of 3.7% (3700 s exposure) and 7.0% (98 s exposure).
• Demonstrated the feasibility of real-time X-ray imaging for diffraction studies with the micro-PIC.

Conclusions:

• The micro-PIC is a viable and effective detector for X-ray diffraction studies.
• The fast-readout system allows for efficient data collection, even with short exposure times.
• This technology has the potential to significantly advance real-time crystallographic analysis.
