Software development for studies of diffuse scattering using CCD-detectorsand synchrotron radiation sources

A graphical-user-interface based software system was developed to cover adv anced data processing requirements which arise from studies of diffuse scat tering in disordered minerals using synchrotron radiation sources and CCD-d etectors. The software includes interfaces to standard applications, proced ures for numerical processing of large data sets, corrections for sample ex ternal scattering and detector-specific distortions, different scaling opti ons to correct the data set against the varying primary beam intensity as w ell as procedures to reconstruct arbitrary slices in reciprocal space on a regular grid. The software system was successfully applied in studies of di ffuse scattering in disordered REE-doped germanates, phase-transition studi es of synthetic titanite and studies of the thermal recrystallization behav iour of radiation-damaged (metamict) minerals.
