Abstract
It is inferred that by frequency filtering the logarithm of the time-of-flight spectrum of neutrons that have passed through a powdered isotropic crystalline
sample a diffractogram may be obtained with many desirable properties for achieving high-quality refinement of structural parameters.
Apart from multiple scattering no wavelength-dependent effects or corrections need to be introduced, which implies
automatic internal calibration of the Bragg intensities.
For utilization of the inherent high resolution of the transmission geometry, a Fourier chopper in the
pulsed beam from an intensity-optimized quasisteady-state moderator is suggested. Results of model calculations are presented.
