Abstract: | Using our custom‐made diffraction apparatus KOTOBUKI‐1 and two multiport CCD detectors, cryogenic coherent X‐ray diffraction imaging experiments have been undertaken at the SPring‐8 Angstrom Compact free electron LAser (SACLA) facility. To efficiently perform experiments and data processing, two software suites with user‐friendly graphical user interfaces have been developed. The first is a program suite named IDATEN, which was developed to easily conduct four procedures during experiments: aligning KOTOBUKI‐1, loading a flash‐cooled sample into the cryogenic goniometer stage inside the vacuum chamber of KOTOBUKI‐1, adjusting the sample position with respect to the X‐ray beam using a pair of telescopes, and collecting diffraction data by raster scanning the sample with X‐ray pulses. Named G‐SITENNO, the other suite is an automated version of the original SITENNO suite, which was designed for processing diffraction data. These user‐friendly software suites are now indispensable for collecting a large number of diffraction patterns and for processing the diffraction patterns immediately after collecting data within a limited beam time. |
