A Neutron Spin Echo (NSE) spectrometer is nearing completion at the NIST Center for Neutron Research. NSE spectroscopy measures the pair correlation function with respect to wave-vector transfer and time, unlike other neutron spectrometers, which measure the scattering as a function of wave-vector and energy transfer. The NIST NSE spectrometer can measure wave vector transfers from 0.01 Å-1 to 2 Å-1. The accessible time range for a particular setting of the spectrometer extends to nearly 10-7...A Neutron Spin Echo (NSE) spectrometer is nearing completion at the NIST Center for Neutron Research. NSE spectroscopy measures the pair correlation function with respect to wave-vector transfer and time, unlike other neutron spectrometers, which measure the scattering as a function of wave-vector and energy transfer. The NIST NSE spectrometer can measure wave vector transfers from 0.01 Å-1 to 2 Å-1. The accessible time range for a particular setting of the spectrometer extends to nearly 10-7 s at the longest accessible wavelengths. We discuss here the expected properties of the NIST NSE spectrometer, provide a description of the strengths of NSE spectroscopy, and give some detail of the considerations necessary for designing a successful NSE experiment.» weiterlesen» einklappen
