The engineering neutron diffractometer E3 at Helmholtz Centre Berlin is constantly being upgraded.
Thus, residual stresses in engineering materials can be characterized by measuring the local crystal lattice strain.
Neutrons have therefore become an attractive tool for industrial applications and the exploration of engineering phenomena.
The latter is to be advanced and hence provides the opportunity to include updates made for the control software and extensions installed to the instrument.
