Co-operation between LLB and SINQ/PSI (under final stages of negotiation) for the installation of the most recent SANS instrument of LLB. It is planned that 50% of the beam time will be dedicated to French users. The start of operation of the SANS-LLB outstation is scheduled for 2022.
More information on the PSI website.
Short description : SANS-LLB is a SANS instrument running with a standard monochromatic mode for the studies of samples with fluctuations of typical sizes varying from the nanometer scale to few hundred nanometer. PA20 is equipped with a beam polarization option and is adapted for high magnetic fields (10T). Moreover, X-Y sizable slits in the collimator allow for GISANS measurements of surfaces and interfaces. The two X-Y detectors (rear and front detectors) allow for a large coverage scattering angle in a single measurement.
