reduced; furthermore, part of the beam can be used for experiments where VCN are required. The neutrons are transported to five experimental platforms, where scientic users can connect their own experiment: The ... is dedicated to experiments using very cold neutrons. The platforms PF2/MAM, PF2/UCN, and PF2/EDM can be used for experiments with ...

bring their whole experimental apparatus to PF2 to connect it to one of our beam ports. Our source can serve four experiments with UCN (PF2/MAM, PF2/UCN, PF2/EDM, PF2/TEST), and one experiment using VCN

turbine of PF2 is a mechanical device which slows down (cools) neutrons the same way a tennis player can slow down a tennis ball (Doppler effect).The reactor generates neutrons whose speeds (energies, te

find the sample orientation and then rotate it to the desired orientation. Then the oriented sample can be glued at the tip of the sample holder which will be used for measurements on the ILL spectrometers

orient samples and also to assess their quality. If the intensity of diffracted spots measured, this can be used for structure determination.

it is still so fast that diffraction patterns that previously took minutes with photographic film can now be obtained in seconds.

individual protons or deuterons of special interest, water structures or other small molecules that can be marked with deuterium to be particularly visible. Data collection is feasible for samples with unit-cell

measurements, either with unpolarised or polarised neutrons, in the incident wave length range 1–3 Å. It can support large sample environments (pressure cells, up to 30 kbar, high field cryomagnets, up to 15T

along the c-axis, in terms of group theory. This small AF moment (1 μB is expected for a spin 1/2) can be interpreted interms of spin reduction in S = 1/2 Heisenberg AF chains. More details in : Tomiyoshi
