Left: See an image of a 3.6-millimeter-diameter, 40-micrometers-thick, 30-milligram boron-filled diamond shell. Right: (a) Visible imaging composite showing (1) shell pellet hitting the boundary of the plasma, (2) continuing through the q=3/2 surface, and (3) ablating and releasing boron dust in the core. (b) Expanded view of (3), highlighting shell and dust. Injection velocity ≈ 230 meter/second.
