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.

peaks tend to broaden because there is not a single interplane distance any longer but rather a distance distribution. To prove this, it is enough to deform a metal sample placed in an X-ray or neutron ... tensile) changes distances between crystal planes, which translates into a modification of the corresponding diffraction angles. For a given ...

The stress scanner Measuring residual stress in a material amounts to making a map of its local deformations. Just like a medical scanner makes an image of the human body interior, what is sought here ... here is non-destructive examination able to image the internal stress repartition inside a smaller or larger manufactured object.
