are fed with tremendous amounts of data from billions of users, the large data from synchrotron or neutron experiments are orders of magnitude smaller (typically in the mega or gigabyte range). Nevertheless ... Nevertheless, some of these algorithms have already successfully been applied to data sets taken from neutron spectrometers [2] . While the ...

First test of an 3He neutron spin filter The nuclei of a helium-3 gas (3He) can be polarised. Thanks to the strong spin-dependancy of the neutron absorption a bottle filled up with that polarised gas would ... would be an effective neutron polariser even for large white beams. This technique was made trully operational for the 1st time in November ...

First experiment with the 3He neutron spin filter During this first test of an 3 He neutron spin filter, the neutron-beam polarisation transmitted by the filter could be determined with high accuray from ... from spin dichroism measurements. It was verified that no significant relaxation was induced by neutron capture and that the wavelength ...
