Abstract

A new apparatus for dynamical texture measurements using neutron diffraction has been developed. A variable wavelength neutron spectrometer has been modified to incorporate a linear position-sensitive detector. The sample is orientated by a fully automatic Euler goniometer, and it can be heated by a stream of hot air at rates up to 200℃/min. A quarter of a complete pole figure can be recorded in 14 minutes with an accuracy, determined by counting statistics, of 2–3%. The experimental set-up is described in the present paper and the performance, including sources of systematical errors, is discussed. Finally the viability of this apparatus is demonstrated by studies of the recrystallization kinetics of 95% cold rolled copper.
