A versatile automated sample changer for texture measurements on the high pressure-preferred orientation neutron diffractometer

摘要

An automated sample changer with an Eulerian cradle for neutron texture measurements is described. This device has been measuring over 2300 texture and almost 400 powder samples at ambient conditions since it became operational in 2002 for use in the high pressure-preferred orientation diffractometer at the LANSCE neutron scattering facility. Operation for almost a decade resulted in sustained enhancements of mechanics, electronics, and software which significantly improved reliability and resiliency. We also describe in this paper our platform independent computer program POD2K which we use to create publication quality pole figure plots for texture samples. © 2010 American Institute of Physics Article Outline INTRODUCTION SAMPLE CHANGER CHARACTERISTICS Mechanical Software DATA ANALYSIS DISCUSSION AND RESULTS SUMMARY AND OUTLOOK
