Scientific Review: The Structure Powder Diffractometer SPODI

Abstract

The structure powder diffractometer SPODI at FRM II is a common project of Darmstadt University of Technology, Ludwig-Maximilians University Munich, and Technische Universität München. The main objectives of the instrument are to achieve a high Q-resolution and to provide a versatile and powerful sample environment. In addition to common applications of high-resolution powder diffraction to determine crystallographic and magnetic structures, the diffractometer SPODI is developed particularly for materials science applications. Prior to the construction, individual components as well as the whole instrument have been simulated by Monte Carlo technique applying the McStas software [1 Lefmann, K. and Nielsen, K. 1999.
