An experimental system has been developed for the study of low-energy positron diffraction (LEPD) with a slow-positron beam generated by a linear-electron-accelerator (linac). Diffraction patterns of a Ge(001)-2 × 1 surface structure have been observed with a normal positron incidence. This is the first LEPD observation with a linac-based high-intensity pulsed slow-positron beam. [DOI: 10.1380/ejssnt.2018.313]
