Abstract
A program to investigate the mixing of a marker layer in a convergent cylindrical geometry has been carried out on the Omega laser facility. The principal diagnostic for these experiments was the Los Alamos National Laboratory (Los Alamos, NM) QXI framing camera. The results obtained displayed an unphysical pattern, partly attributed to nonlinear gain effects. We propose a method to compensate for these effects, which relies only on shot data and so can be used retrospectively on previously obtained data. Modifications carried out on the camera to minimize the effect are described and the results are compared with compensated data from previous runs. We also present results which evaluate the state of gain effects in the camera during each experimental shot day.
