Simulated experiment SuperADAM operates as a fixed wavelength neutron reflectometer The neutron beam from the cold neutron guide H521 arrives at the monochromator which selects a narrow wavelength band ... the unwanted harmonics. Optionally the beam can be polarised simultaneously (i.e. select only the neutrons which have spins all in the same ...

How neutron spins behave Here D7 is shown in its spin-flip (SF) configuration. Unpolarised neutrons are reflected by the graphite monochromator. The incident neutron beam is polarised by the supermirror ... measurement of SF cross-sections, the neutrons are spin flipped by the flipper. Flipper is turned off when measuring non spin-flip (NSF) ...

essential, a knowledge that can only be obtained from accurate structural and dynamical data. Therefore neutron diffraction data are essential. An important compound of this type is the complex RuH 2 (H 2 ) 2

was not designed to include much metadata, or MIME additions. Work started on a specification for Neutron Data. Several centres adopted the format, though quite often only partially, older home grown formats ... formats still predominated. Meetings advanced with the adoption of HDF version 4 by several neutron centres. Unfortunately there was great ...
