A link to a Debye-Scherrer diffraction image of ceria (cerium oxide), collected with a cylindrical Imageng-Plate camera at BL5S2 beam line of Aichi Synchrotron Radiation Center (AichiSR) on October 13, 2013, is presented. The image may be the finest Debye-Scherrer photograph in human history, and it is possible that finer Debye-Scherrer diffraction photograph would not be taken in the future.
