(I'm not sure that people outside of the bomb building industry really know *for sure* what the geometries used in the atomic weapon that sets off the fusion reaction.)

Perhaps. However, there is much detailed design and production info in the "Nuclear Weapons Databook" series: U. S. Nuclear Warhead Production, Volume II, 1987. U. S. Nuclear Warhead Facility Profiles, Volume III, 1987. Soviet Nuclear Weapons, Volume IV, 1989. And others. The series provides pretty detailed textual and graphic descriptions of the entire history of design, production, testing and deployment of nuclear weapons. These are written by the folks at Natural Resources Defense Council and are available there and from Ballinger Division, Harper and Row, New York. The beloved McGeorge Bundy is quoted on the covers: "A powerful antidote to the simplistic deceptions peddled with such zeal from high places . . . contains more facts about the past, present and future of [U. S. nuclear] forces than have ever been put in one place before . . . meticulous and responsible . . . the effect is overwhelming." They are mesmerizing. But then maybe they were written only for the ignorant. John
