How big is the step from a fission bomb to a fusion bomb?Do you simply put H next to some fission bombs?

More or less, one puts some form of hydrogen, e.g. DT, or LiD in a configuration where it was undergo fusion. The fission trigger simply provides the energy used to compress and heat the DT or LiD. At DT can be placed in a fissile device to boost its yield.
The devil is in the details.
Thank you.I thought the fission bomb had only to create the heat and pressure of the sunDatafree,
NOT simple AT ALL!!! It's more difficult than just putting H next to a fission bomb.
As Astronuc points out; the devil is in the details and it took years to figure out how make
a workable hydrogen bomb even though it was conjectured to be possible back during the
If you are interested - read Richard Rhodes book "Dark Sun: The Making of the Hydrogen Bomb"

Jeff,Yes, it's really just as simple as that. No one who actually knows anything about this stuff can or should comment.
No, not really. The book is out there, you can find it in every good library, you can order it on amazon and all that. I really think it doesn't contain any undisclosed material. I've read it, and it contains far more detailled information than what Greg said here - and one can also imagine that it is still far from containing useful design information to quickly make a bomb. It is an interesting story of physics too. To summarise the argument: the "naive" idea that the fission bomb materially (hydrodynamically) compresses and heats the hydrogen was the wrong way, and led people astray for a while. The actual idea that worked was to use *radiative pressure*. This sounds crazy at first, as radiative pressure seems to be quite elusive as compared to hydrodynamical pressure - for matter in normal circumstances. But it turns out that in the thermodynamical states one is interested in, radiative pressure is far stronger than hydrodynamical pressure, and moreover can be much better concentrated.My concern is your reference to a book for more information, which could be construed to imply some kind of official blessing. I have no idea what is in the book, I've never read it, but as you must know it could potentially skirt the line.
