X-Ray and Neutron Instrumentation

Abstract

The basic procedure for any analysis involving structure determination, as outlined in Chapter 3–7, is to accumulate reliable experimental small-angle scattering data. The experimental technique for X-ray and neutron structure analysis involves small-angle scattering instrumentation, which is reviewed elsewhere (Glatter and Kratky, 1982; Schelten and Hendricks, 1978). Here we deal only with specific features of the small-angle scattering experimental technique, basic principles underlying the design and construction of small-angle scattering facilities, and some aspects of the experimental procedure. The main difficulty of small-angle scattering intensity measurements is that the powerful primary beam does not permit one “to approach” the sufficiently small angles very closely.
