IUCR Diffraction Microstructure Imaging round-robin measurements

It is critical to understand and compare the diffraction microstructure imaging capabilities between different 3DXRD/DCT instruments implemented at synchrotron sources around the world. The Diffraction Microstructure Imaging Commission has embarked on an initiative to collect 3DXRD/DCT/PCT data from different instruments for this purpose. An initial series of measurements on a set of titanium and nickel samples were conducted at the Advanced Photon Source (APS) in the US pre-shutdown and Petra-III at DESY in Germany. Now, it is the ESRF's turn to measure these samples before they are passed to other lightsources in Europe (SOLEIL, DIAMOND, MAX IV...).

深入理解并对比全球各地同步辐射光源上搭载的各类三维X射线衍射/衍射衬度断层扫描（3DXRD/DCT）仪器的衍射显微成像能力，具有至关重要的意义。为此，衍射显微成像委员会（Diffraction Microstructure Imaging Commission）已启动一项专项倡议，旨在从不同仪器采集3DXRD/DCT/PCT数据。此前，研究团队已在美国先进光子源（Advanced Photon Source, APS）的停机预实验阶段，以及德国电子同步加速器研究所（DESY）的PETRA-III装置上，针对一组钛与镍样品完成了首轮测量。如今，轮到欧洲同步辐射装置（ESRF）对这批样品开展测量工作，后续这些样品将被送往欧洲其他同步辐射光源，包括SOLEIL、DIAMOND、MAX IV等。
