2.8.1. Introduction

Some salient differences between neutron diffraction and X-ray diffraction are that

  • (a) neutron beams are not available in standard (`home') laboratories,

  • (b) the available neutron fluxes are small even at a high-flux reactor and even when compared with laboratory X-ray generators (Scherm & Fåk, 1993[link]),

  • (c) absorption is negligible in most materials (see Section 4.4.6[link] ), and

  • (d) magnetic scattering is a strong component (see Section 4.4.5[link] ).

All these differences have effects on the use of neutrons for diffraction imaging (hereafter called, according to standard usage, neutron topography), while the obvious similarities in scattering amplitude and geometry make such topography possible. The effect of (a) is that the first attempts at neutron topography occurred late, with the work of Doi, Minakawa, Motohashi & Masaki (1971[link]), Ando & Hosoya (1972[link]), and Schlenker & Shull (1973[link]), and that it is practised at very few places in the world, though one of them, at Institut Laue–Langevin (ILL), is open to external users.
