This schedule is provided for assistance in scheduling experiments and sample environment. While every effort will be made to keep this schedule updated with the latest information, please visit the HFBS operating schedule for official dates. Do not use this information for travel plans.


The NCNR backscattering spectrometer is one of the highest intensity instruments of its kind. It enables very high energy resolution studies of the low frequency dynamics of many systems. Applications of backscattering spectroscopy are numerous and include molecular reorientations, dynamics of adsorbed systems, and viscous liquids. To learn about the instrument, and about experiments that have been performed on the HFBS, please use the links above to visit our webpages.

Access to the NCNR

If you have an idea for a measurement, and want to discuss feasibility and other practical matters, please contact one of the instrument scientists. If this is the first time you will be doing an experiment on HFBS, we strongly encourage you to discuss your plans with one of the local contacts.

Applying for beamtime (submitting requests and proposals)

To obtain beamtime on the HFBS, you must submit either a request or a proposal, both of which can be accessed by clicking here

Research done on this instrument is supported through NSF grant, DMR-1508249
