Yes, after the test ban treaties, there was a huge push into exploring mathematical emulations of all aspects of fusion, and all assorted bombs, as well as laser ignition of pellets with these large lasers using inertial confinement of the pellet as the laser impacted it - analysing the fusion by observation of emitted neutrons. xrays etc. They issued reports from time to time(sanitised), and probably used the secret data to fine tune emulated weapons with fact points. The pellets were composed of potential fuels, various Hydrogens and Lithiums, varied in composition to explore the ignition space. A number of pellets performed well in terms of gain, but were far-far from useable fusion when the LL labs costs were factored in. I think they determined it could not ever work as a fusion energy source, but it provided data. They still mine data from it with various elemental mixes making up the pellets.
