Data of pink-beam serial synchrotron crystallography at the Pohang Light Source II

Abstract

Serial synchrotron crystallography (SSX) helps to determine the room-temperature structure of macromolecules with minimal radiation damage. Pink-beam X-ray provides more photon flux than a monochromatic beam, which can increase the diffraction intensity of crystal samples and reduce the issue of partial reflection measurement compared with a monochromatic beam. The demonstration of pink-beam SSX at the 1C beamline at the Pohang Light Source II (PLS-II) was previously reported. The Bragg peaks observed in SSX diffraction data using a pink-beam exhibited a slightly stretched shape, unlike that from a monochromatic beam. Therefore, it is necessary to develop an indexing algorithm that can efficiently process the Bragg peak generated by pink-beam SSX. Therefore, the collected pink-beam SSX diffraction data can be tentatively used to develop an indexing program for Bragg peaks generated using the pink-beam. In this study, detailed information on the diffraction data of pink-beam SSX at PLS-II was reported to access the raw data and process the information.
