Yes, I can see the complexity there, which is why I'm not us-

pellet blasted into the thrust dome.

You are truly clueless.  The magnetohydrodynamic injector is a pump
that injects the propellant, in this case the pellet you describe, and
the thrust dome as you call it is indeed the jet.  If the jet is well
collimated your rocket is fairly efficient, if the jet is not well
collimated, it is less efficient.

It's useless to argue semantics. Is there a magnetohydrodynamic
injector that is patented as a pump? (Probably not, because
I've already "invented" one!) The "jet" is more like controlled
"blast",
but sure, it's collimated: as the density radius product of the im-
ploded pellet is raised beyond a few hundred, with a pellet density
greater than 100,000 times the liquid density. X-rays are trapped
with laser energy outputs of 104 joules, at 50% efficiency.

As the pellet becomes imploded tenfold in radius (1,000 times
in volume), the confinement time is also reduced tenfold, and the
burn time is reduced by a factor of 1,000. The burn efficiency is
therefore increased by a factor of 100 to 10%, yielding 30 times
the laser input energy.
