Abstract

This paper demonstrates the great value of verticallt bent pyrolytic graphic crystals used as monochromator or analyzer in triple-axis neutron spectrometers. A simple model is presented for estimating the flux gain to be achieved by bending the monochromator or analyzer, and the effects this bending has on instrumental resolution are also considered. Experiments with three monochromators bent to 50, 35, and 21 inch radii over a wide range of neutron energy (5 to 40 meV) gave a maximum flux gain factor of 3.5 as predicted by the model, with no measurable change in resolution. In addition, if vertical resolution is not crucial, a further intensity gain can be achieved by using a bent analyzer.
