The distinction of frame overlap and the cohesion of time-of-flight diffraction patterns collected at various scattering angles

Abstract

The possibility of combining time-of-flight powder neutron-diffraction patterns collected at different scattering angles is examined, with a view to increasing data-collection rates by the use of a large total solid angle and by including multiple frame overlaps. The basic design features of the required diffractometer are enumerated and a test experiment, using a spectrometer possessing basic characteristics pertinent to the proposed diffractometer, is used to evaluate these assertions.
