Data collection of quasicrystals by IP Weissenberg camera

Abstract

For a data collection by an imaging plate (IP) Weissenberg camera, a set of softwares has been developed, which enables us to index diffraction patterns of quasicrystals and any other quasi-periodic crystals and to obtain their integrated intensities. The indexing uses two Weissenberg photographs taken with different coupling constants. In IP Weissenberg cameras, a higher-order correction of the Lorenz factor is necessary for some reflections and a correction of the fading phenomenon of IP is important.
