Salsa - Strain imager for engineering applications
Strain analyser 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 instrument is shown with a turbine Ti blade mounted on the hexapod. The Delta Table and the slits are clearly visible. The beam flies from right to left into the two dimensional detector (covered by black boron carbide rubber).
The Hexapod, i.e. the sample manipulator
It 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.
