This animation shows a view of the reaction vessel in our reactor concept. The target is dropped into the reaction chamber from above, falling under gravity. The projectile is launched downwards on top of the target and catches it up in the centre of the chamber. The impact is focused by the target and a pulse of fusion energy is released. That energy is absorbed by the lithium flowing inside the vessel, heating it up. The lithium protects the vessel from damage, allowing it to last for the whole lifetime of the plant without replacement.
