FaME38 - Improving the Effectiveness of Strain Measurements
FaME38 is a new facility at the ILL/ESRF in Grenoble with the aim of improving the accessibility and effectiveness of neutron and synchrotron strain measurements. In addition to providing basic materials engineering facilities, it enables users from both commercial and academic backgrounds to prepare and to evaluate experiments on-site. The real success and impact of a strain scanning experiment depends on the quality of the collected data and its practical use. FaME38 provides a knowledge base and tools which can increase the efficiency of the measurement. These tools include a VAMAS standard sample base-plate, a materials support laboratory and enhanced visualisation software. The VAMAS base-plate allows pre-configuration of the sample position and set-up, as well as so-called “hot-swapping” of samples with minimum time required for re-configuration of the instrument. The visualisation tools feature web-based simulation and, in particular, 3D visualisation of both the experimental environment as well as the data. The use of the support facility can significantly reduce the set-up time, thus increasing the time available for measurement. The visualisation naturally enhances the understanding of the data and ties in with existing engineering code such as CAD/FEA software. We demonstrate how the use of additional technology can improve the effectiveness and impact of strain mapping experiments at neutron and synchrotron facilities by disseminating the workflow of a typical experiment undertaken in the FaME38 framework. This approach is aimed at paving the way toward technology-oriented application of synchrotron and neutron strain scanning.
