Is this what India would use too, or Botswana, if it had to make a TN bum.
Looking at the 2:1:4:6 ratio posted by LakshmiC - the "6" is tamper going boom What other tampers can be used if at all?
Open source says that some US nuclear warheads inject Tritium gas into thw core just before detonation. Storage of gas outside in this manner makes it unnecessary to service the core (which is necessary with cores filled with Li 6 Deuteride).The external Tritium gas can be replenished reqularly.
What was used in the single Indian test?
The following ref uses the deadly "S" word, "scalable" (bolded+underlined in the quote below) What does it mean?

[quote] For the secondary to be imploded by the hot, radiation-
induced plasma surrounding it, it must remain cool for the first
microsecond, i.e., it must be encased in a massive radiation (heat)
shield. The shield’s massiveness allows it to double as a tamper, adding
momentum and duration to the implosion. No material is better suited
for both of these jobs than ordinary, cheap uranium-238, which
happens, also, to undergo fission when struck by the neutrons produced
by D-T fusion. This casing, called the pusher, thus has three jobs: to
keep the secondary cool, to hold it, inertially, in a highly compressed
state, and, finally, to serve as the chief energy source for the entire
bomb. The consumable pusher makes the bomb more a uranium fission
bomb than a hydrogen fusion bomb. It is noteworthy that insiders never
used the term hydrogen bomb.
Finally, the heat for fusion ignition comes not from the primary but
from a second fission bomb called the spark plug, imbedded in the heart
of the secondary. The implosion of the secondary implodes this spark
plug, detonating it and igniting fusion in the material around it, but the
spark plug then continues to fission in the neutron-rich environment
until it is fully consumed, adding significantly to the yield.
The two-stage, radiation-implosion, Teller-Ulam superbomb is like
an ecosystem in which nothing is wasted. The pieces fit like a jigsaw
puzzle. Every component contributes to overall yield, often in more
than one way. Oppenheimer declared it “technically so sweetâ€
