Abstract

The greatly increased flux that will be available at the Spallation Neutron Source (SNS) should enhance our ability to carry out time-resolved reflectivity measurements. Construction of horizontal- and vertical-surface reflectometers is well underway and the instruments will be commissioned in early 2006. We consider how to utilize the intrinsic wavelength bandwidth of the SNS to perform "snapshot" reflectivity measurements, using the outgassing of a hydrogen-charged Fe/Nb multilayer as a test case. At the expected SNS source flux of 2 MW, we determine that kinetics in our rather favorable test case can be observed with as short as a 1-s time resolution.
