Neutron Beam Facility It is a very versatile diffractometer for magnetic structure analysis. It offers several set-ups: a high field set-up for 1D polarimetry up to 10 Tesla ; a zero-field set-up for spherical ... spherical neutron polarimetry with CRYOPAD ; a non-polarized set-up for experiments requiring both short wavelengths and high magnetic ...

High field setup Here, D3 is equiped with a 10 Tesla cryomagnet with a wide opening angle and a lifting detector. The neutron beam is polarised vertically. Large portions of the reciprocal space can be

Zero field setup Here, D3 is equiped with CRYOPAD and a 3 He spin filter (DECPOL). This makes it possible to monitor separately the polarisations of the incident and scattered beams, in 3 dimensions.
