Cryogenic Flippers/Polarisers We propose two cryogenic devices for polarising the beam and flipping the neutron polarisation. The first one, called Cryopol for 'Cryogenic Polariser', is owned by the CEA ... Neutron Optics team have constructed very large spin filter cells covering the full section of the beam (6 x 20 cm2 at the cell position) and ...

rs. Benoit Mestrallet placing a freshly polarised 3 He cell on D3, the Spin Polarised Hot Neutron Beam Facility. For the transport from Tyrex-2 to the instrument, the cell is placed in a special transport ... the assembly which, on the TAS spectrometer, makes it possible to polarise and analyse the neutron beams.

Simulated experiment A polychromatic (white), neutron beam is partially monochromatised by the two counter-rotating disc choppers, generating a packet of neutrons which then falls upon the monochromator ... angle selected to define the desired neutron wavelength by Bragg’s Law. The reflected monochromatic beam then passes to the Fermi chopper, ...

the principal challenges during strain experiments is the movement of the specimen about the neutron beam (gauge volume). SALSA uses a unique hexapod design which has significant advantages over traditional ... during an experiment. A 300mm diameter, 500mm long steel pipe section is maneuvered around the neutron beam for measurements of lattice ...

Computer drawing of UFO A simulation of UFO beam-trajectories Multi-analyzer IN12-UFO As a further option, IN12 will be equipped with a 2-dimensional position sensitive detector and an array of fifteen ... fifteen analysers which can be rotated and positioned individually in order to map the scattered beam on a user-chosen path in Q-space. ...
