Query: Bayesian inference of inaccuracies in radiation transport physics from
  inertial confinement fusion experiments   First principles microphysics models are essential to the design and analysis
of high energy density physics experiments. Using experimental data to
investigate the underlying physics is also essential, particularly when
simulations and experiments are not consistent with each other. This is a
difficult task, due to the large number of physical models that play a role,
and due to the complex (and as a result, noisy) nature of the experiments. This
results in a large number of parameters that make any inference a daunting
task; it is also very important to consistently treat both experimental and
prior understanding of the problem. In this paper we present a Bayesian method
that includes both these effects, and allows the inference of a set of
modifiers which have been constructed to give information about microphysics
models from experimental data. We pay particular attention to radiation
transport models. The inference takes into account a large set of experimental
parameters and an estimate of the prior knowledge through a modified $\chi^{2}$
function, which is minimised using an efficient genetic algorithm. Both factors
play an essential role in our analysis. We find that although there is evidence
of inaccuracies in off-line calculations of X ray drive intensity and Ge $L$
shell absorption, modifications to radiation transport are unable to reconcile
differences between 1D HYDRA simulations and the experiment.
