The diffusion of oxygen in silicon single-crystals The small-angle neutron-scattering from SiO 2 precipitates in a single crystal of silicon which has been heat treated for 500 hours at 600°C; the neutron ... neutron beam was incident along a <100> direction. The central cross arises from the cushion shaped SiO 2 precipitates lying on (100) planes ...

from the vortex lattice in the type II superconductor MgB2. This experiment revealed the anisotropic nature of the double-gap behaviour in MgB2. The sample was a 98 microgram crystal, surely a record for ... from the vortex lattice in the type II superconductor MgB2.

users can connect their own experiment: The platform PF2/VCN is dedicated to experiments using very cold neutrons. The platforms PF2/MAM, PF2/UCN, and PF2/EDM can be used for experiments with ultracold neutrons ... during the time of storage of UCN in one experiment, another experiment can be fed. The platform PF2/TEST is operating at a lower flux. ...

The instrument zone PF2 is an ultracold neutron (UCN) source consisting of a straight then curved vertical neutron guide which selects very cold neutrons (VCN) with a speed of only 60 m/s. Then, these ... transforms neutrons into UCNs with a velocity range from 0 to 15 m/s. The VCNs and UCNs produced by PF2 are distributed to a series of ...

dashed-dotted curve refers to the Maxwell spectrum at the turbine blade ends (up to a lateral velocity of 6.2 m s -1 ).

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 (PF2/VCN) simultaneously ... PF2 - Ultracold neutron facility Ultracold neutrons (UCN) with wavelengths around 1000 Å have several unique features: one of them is ...

Principle of the ILL neutron turbine The neutron 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
