A new in situ centrifugation set-up for the separation of fluids by SANS and Diffraction
We propose to develop a new generation of sample environment never used so far at any neutron scattering center nor synchrotron while commonly used in soft matter laboratory : it is based on centrifugation principle, where the new key control parameter is the degree of acceleration expressed as multiples of gravity. A density gradient will be generated in the sample, which gradually will induce phase transformations and nanophase separation. The new set-up is a vertical centrifugal machine, with 8 hellma cells (thickness of 1 mm, or 2mm) inserted in a rotating disk; we plan to impose 1000 to 6000g on various samples at room temperature. Such experiments in the context of low energy and eco compatible solvents have been never used by neutron scattering (nor X-Rays) for the analysis of phase transitions. All SANS diffractometers are equivalently possible. This proposal in a simpler form was submitted last year and was asked by the ILL to become a Long Term Proposal because of its very innovative approach. We ask for 4 days per year on a SANS instrument and 4 days on D16.
