passing the particles through a magnetic field with a gradient. This causes the originally uniform beam to split into two clearly distinct families, which are referred to as the spin states of the electron

filters that the ILL has developed to measure the polarisation of neutron beams and the intense beam provided by the cold neutron beam facility PF1B. The experiment was performed and analysed in a collaboration ... lifetime of 879 seconds, while the beam lifetimes were considerably longer at 888 seconds. In 2018, theorists suggested that the ...

sing silicon monochromator that enables the instrument to concentrate the ILL’s high flux neutron beam onto a sample measuring several millimetres in dimension, thus providing the instrument with a unique

in a wide q-range with the instrument. With an incoming beam of wavelengths comprised between 2 Å and 30 Å, and M=4 supermirrors to deflect the beam, it is possible to attain a q-range up to 0.42 Å-1 (reflection ... (not to scale). For neutron reflectivity, membranes were formed on quartz and an incident neutron beam was transmitted through the ...
