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

An advanced neutron strain analyser SALSA is designed for actually performing diffraction measurements on "real" engineering components and is optimised for stress determination in metallic components

The benefits of having 6 legs One of the principal challenges during strain experiments is the movement of the specimen about the neutron beam (gauge volume). SALSA uses a unique hexapod design which

Instrument no longer available D19 - Thermal neutron single crystal diffractometer The large structures diffractometer D19 is the monochromatic thermal neutron single crystal diffractometer of choice

General view of the instrument

Simulated experiment The white beam (polychromatic) from the thermal tube H11 arrives at the monochromator. Monochromatic diffracted beams reache the sample – a single crystal - located at the centre

The power of D19 The large PSD of D19 and its relatively short wavelength makes it possible to record up to 3500 Bragg reflections at a time. The movie shows a set of diffraction pattern from a small

Hydrogen bonding in a phosphorium aryl axideDark grey: carbon, light grey: hydrogen, red: oxygen, green: phosphorus. Single crystal D19 is a valuable tool for the study of: Organometallic complexes Hy
