Salsa - Strain imager for engineering applications

SALSA is the ILL stress imager dedicated to the determination of residual stresses in a broad range of applications in terms of components and materials. It is designed for diffraction measurements in "real" engineering components and optimised for stress determination in metallic components.

General view of the instrument. The Delta Table and the slits are visible. The Hexapod, i.e. the sample manipulator, consists of a 6 legs hydraulic system, like those for flight simulators. It can move the sample up and down, translate it and rotate it in any direction.

The Si double focusing monochromator - its reflectivity is particularly high at wavelengths about 1.7 Å using the (400) reflection and at 2.5 Å using the (311) reflection.
