Background-filtered transmission diffraction with internal intensity calibration

Research output: Contribution to journalArticleScientificpeer-review


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.
