DCS Scientific Opportunities
A broad range of scientific problems can be tackled using the NCNR Disk
Chopper Spectrometer. Quick survey experiments, on materials whose
microscopic properties are poorly known or completely unknown, may
be performed under low resolution conditions but with good intensity.
More focused measurements may then be undertaken selecting an
instrumental setup appropriate to the problem at hand.
Phenomena that can be investigated include translational and
rotational diffusion processes, which provide information about
time scales, length scales and geometrical constraints; the
ability to access a wide range of wavevector transfers, with
good energy resolution, is key to the success of such
investigations. Low energy vibrational excitations and densities
of states can also be studied, as well as tunneling phenomena.
Materials that can be studied include molecular and porous
systems, layered materials, catalysts, glasses, polymers, metal-hydrogen
systems, and biological and magnetic systems.
