Neutrons can reveal motions and dynamical changes in molecules like polymers and water because they can interact with these motions at given energies. The resulting characteristic energy changes can then be ... conducting electrolyte through which charge carriers – ions like hydrogen (H + ) or hydroxide (OH - ) can travel between the electrodes ...

from the neutrons leaving the horizontal cold source. Other wavelength resolutions (from 8 to 20 %) can be obtained by manually rotating the selector. The selector has a 25 cm long rotating drum with helical ... ional mould. The maximal speed is 28300 rpm filtering a wavelength of about 0.45 nm. The selector can be manually rotated around its ...

development – the polarisation efficiency is 100% and there is not much else we can do. It is very possibly the best polariser we can produce today,” says Nesvizhevsky. This improved performance has also attracted ... manipulations needed to make a stack. Due to the technology of solid-state polarisers, the whole device can also be made much ...

options are mostly superfluous and can generally be ignored by the user. The "dets" option can be used when only one detector is taking data, and the "disk" option can be used when the numor files are not ... g. due to erroneous detector positioning) can be listed in the ignore file (default: "ign.ign") and will be consequently skipped over by ...

Allocation scheme has been introduced for SANS experiments on D22 . Block Allocation Group (BAG) proposals can be submitted by groups of at least three teams (maximum of eight), preferably including teams with ... at a given time. BAG proposals will be evaluated for one-year period (two scheduling periods); they can be renewed for another term ...

and novel magnetic materials. Heavy nuclei can be split with neutrons. This can shed light on a number of still unknown processes in atomic fission. Neutrons can also be captured by nuclei. The process releases ... introduction to neutron science - the uniquess of neutrons, neutron scattering techniques and what can they do for science. What is a ...
