Below are two schematic drawings of H-bombs. In both of them can be seen a grey plate between primary and secondary. What's it for? It transforms gamma rays from the primary to soft X-rays. It is something like 10-15 centimeters thick and made of a high-Z element such as Uranium. It is immediately heated to millions of degrees and is then a completely dissociated plasma that is transparent to soft X-rays, because there are no ions, atoms or molecules in it to absorb such radiation. But there is an awful lot of electrons. They will undergo Compton scattering with the gamma rays from the A-bomb. The thickness of the plate is exactly designed, through simulation and calculation to produce, soft X-rays in the other end. In comes gamma rays and out comes soft X-rays. When they fall on the LiD, there will be a big boom.Sven Andersson wrote:The great eye opener in my case was reading Cagle's theory on how a fusion bomb really works. Can be found in the part The Physics of Successfull Fusion.

The U-238 taper is for shape charge, explosive wave propagation, the styform is the high cross section which turns to plasma, the U238 reflector is Pyrex
