Sounds reasonable. I don't know how these fusion cross
sections scale, but it seems reasonable to assume
a certain lower bound on the mass of the fuel pellet
(depending on geometry) for efficient neutron capture
and sustained burn. Unless you figure out some way
to tamp a very small mass. Good luck

Well, that's the trick, isn't it? Thus far, the only
fusion device to do better than break even is the bomb.
lol. (shows where mankinds priorities are). And, in
order to get a fusion combustion wave in the bomb, fissionable
materials are required at two points. First, the tremendous
radiant flux of the trigger is used to compress the fusion
fuel cell. Then, once compression is attanied, the plutonium
'spark plug' at the center of the fusion fuel assures
the compressed LiD burns. fission (crunch) (a litte fusion)
fission, then finally fusion. Entire process takes less
than a microsecond, and the height of the fission/fusion
burns are mere handfuls of nanoseconds.
It's not clear whether the plutonium spark plug
is needed at the center of the secondary. Obviously
uncle sam isn't eager to volunteer this information.
At least in theory, if you get an efficient symmetrical
compression, just letting the shockwave converge at
the center of the mass may generate enough heat to get
things going.

Assuming you can get your paws on the stuff. It's
restricted I believe. Tritium would be the best bet
for the design you posit.

??? Not completely following you here. If you're
talking about fission reactors, obviously there's
still fission, just hopefully a bit more controlled
than in a bomb.
Unclassified science is funny, I agree. Often you can
learn more from what is not said, or from what is
omitted. And believe me, from my perusal of the info.
out there, quite a bit is still classified.
Best conceptual overview I've been able to find is
Carey Sublette's nwfaq. No doubt you're already aware
of this stuff:

(middle of the page).
Good luck with your dt fus0r. You'll need it. If
you get really lucky you might come up with a
design that can be used as a bomb or a reactor.
I'd stick with dt, as it is available, and not
restricted. If you were to build a bomb using just
dt it would be nearly impossible to detect or trace.
Another thing to keep in mind. Fission triggered thermonukes
(at least in theory) can be scaled to any size. Tsar
Bomba being a demonstration of this. Properly timed and
staged, each subsquent stage feeds on the previous stage,
and each stage is larger, releasing more energy.
Don't burn yourself.
