Larmor

This instrument is in design phase,a proposal .

The business case for LARMOR is predicated on two simple facts: first, that such an instrument will provide a suite of techniques not currently possible at ISIS and second, that it will expand the range of spatial and temporal length scales accessible into wholly new areas. This can be expected to give rise to new science. Much contemporary nanoscience spans a range of length scales. The SESANS technique has the potential to significantly expand the information horizons of those using techniques such as light scattering, confocal microscopy, electron microscopy or freeze-fracture microscopy, both down to shorter length scales (from their perspective) and to quantifiable bulk averages from opaque samples, studied in-situ, in complex environments. And to these important characteristics must be added the discernment provided by neutron contrast variation, for example to aid location of water content. There is certainly scope for SESANS to attract scientific communities which are presently under-represented at ISIS; e.g. food and environmental science. For users of conventional (‘pin-hole’) SANS at ISIS, SESANS will provide access to length scales well over an order of magnitude larger than can be studied even on the new SANS2D instrument. SESANS would also provide complementary information to that from other forms of USANS/USAXS and NMR imaging techniques. The only routinely operational SESANS instrument in the world is the demonstration instrument at IRI/TU Delft. Another (called SESAME) has been proposed for the SNS but is not yet funded. Approximately 22 (perhaps as many as 30) UK and international groups have been identified as potentially able to make use of the SESANS technique to study science areas ranging from foodstuffs and giant lipid vesicles to silicalites and magnetic recording media.
