pulses of fast neutrons catch up with pulses of slower neutrons after the chopper. The chopper speed can be adjusted in such a way that all three pulses of different energy arrive at the same time in the ... velocity of the neutrons. Therefore, if neutrons are scattered by a sample, the time-focussing condition can not be accomplished in general. ...

angle scattering (SAS). They can be applied to samples that are too flexible to crystallize, to macromolecular complexes or to conformational equilibrium. Their results can be analyzed ab initio or by fitting ... between molecules of different nature, such as protein and detergent, while SANS can: using specific deuteration, the detergent can be ...

and reciprocal space can be plotted for custom planes defined by two vectors. In addition, editable integration masks can be drawn and moved over the map Magnetization density can be exported into volumetric ... volumetric data grid files, which can be read by other programs (e.g. Vesta) batch refinements can now be saved to and reloaded from the ...

detector can be changed between 10’ and ˝open˝. The sample table can support the mounting of high-field cryomagnets (up to 12T and 15T, respectively in the polarised and unpolarised modes). IN22 can be operated ... or polarised mode. Vertical guide fields are permanently installed. The incident/final polarisation can be continuously selected in the ...

M6/femelle thread. (pdf - 573 Ki) The standard sample can contain up to Ø15 mm samples, electrodes included. It is possible to use a large sample can when necessary (contact us in advance).

Neutrons can be polarised by reflection (supermirrors), by diffraction (Heusler crystals) or by absorption (polarized ... transmission device, with predictable characteristics no impact on the optical functions of the instrument can be configured into ...

enough, they behave like small magnets that have a north and a south pole and can turn in any direction. Small magnetic particles can be found naturally grown in rocks, but also in some living organisms, such ... electrons, can be regularly aligned. In contrast, the spins are randomly aligned in the structurally disordered surface region of the ...
