abstract = "Bayesian-inference-based approaches, in particular the random-walk Markov Chain
Monte Carlo (MCMC) method, have received much attention recently for X-ray scattering analysis.
Hamiltonian MCMC, a state-of-the-art development in the field of MCMC, has become popular in recent
years. It utilizes Hamiltonian dynamics for indirect but much more efficient drawings of the model
parameters. We described the principle of the Hamiltonian MCMC for inversion problems in X-ray
scattering analysis by estimating high-dimensional models for several motivating scenarios in
small-angle X-ray scattering, reflectivity, and X-ray fluorescence holography. Hamiltonian MCMC with
appropriate preconditioning can deliver superior performance over the random-walk MCMC, and thus can
be used as an efficient tool for the statistical analysis of the parameter distributions, as well as
model predictions and confidence analysis.",
