For x-ray scattering from amorphous media at large sin θ/λ (> 1.00 Å-1) momentum and energy is either imparted to a single electron (Compton effect) or to a single atom (Thermal Spike effect). In both cases the impulse approximation provides a convenient method for treating the scattering. Measurements of the ratio of Thermal Spike scattering to Compton scattering were made on paraffin.
In this study, we measured the Compton scattering spectra of Al, Ag and Au metals changing the harmonic order of X-rays from an undulator. The width of the Compton scattered X-ray spectrum changed depending on the harmonic order of X-rays. This indicates that Compton scattering spectra shape reflects a momentum perpendicular to the traveling direction in Hermite–Gaussian (HG) light.
We categorized 16 contributions into the three sub-fields. Those are 1. Compton scattering X-ray sources, 2. FEL and RF photoinjectors and 3. Plasma wakefield acceleration/innovative acceleration schemes. We performed a half day working group for each sub-field. The titles and summaries of the contributions appear in the article.
The structure of micellar solutions is determined from X-ray small-angle scattering measurements on an absolute scale. The most probable structure is chosen by comparison with spherical cylindrical and lamellar models. This method is applied to two-component micelles and it is possible to follow the variation of micellar dimensions when the concentration of each component is varying.
