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 ...

Principle of the spin-echo technique Spin-echo spectrometers are based on the determination of neutron velocities by using the Larmor precession of their spin in a constant magnetic field. This is a trick ... resolution goes as λ 3 , so it becomes excellent at long wavelength. For example IN15 which can use 24 Å neutrons (wavelength twice the one ...

Simulated experiment A principle of a neutron Laue diffractometer is extremely simple. When a single crystal is placed in a white beam it diffracts neutrons in many directions. The diffracted beams which
