A capacitor bank? Is this to ensure homogeneity in a
compression w. standard explosives triggering scheme?
Actually, I was thinking the caps would be required to fire the ignitors
from a portable power source. However, since I'm not a nuclear weapons
designer or an explosives expert, I'm making a guess on function based
upon what I've read and seen on shows that documented the original
construction of Fat Man. :)
According to at least one movie I watched the part that is critical are
some special triacs so that each charge can be detonated within a fairly
tight time window.
