Diffraction Support Page

The neutron diffraction group is operating the instruments HRPT, DMC, TriCS and Orion at the Swiss spallation neutron source SINQ. Please have a look on our Presentation of the Diffraction Instruments which includes scientific examples as well a an outlook to upgrades of instruments and new instruments.
