I've been reading about fusion lately and I had some questions.
What happens to the helium atoms in the grand scheme of things? Shouldn't they continue to fuse until they reach the heavy atom state where fusion is no longer possible?
Other than the released neutron, other nucleons are released as a result of the fusion yes? What are they?
What can be done to interrupt a self-sustained chain reaction? And how does a reaction 'run out of fuel?'
Is the heating of the plasma itself the ignition for the reaction? Are the atoms always in motion then?
