A magnetic mirror induced by an axial magnetic field typically collates the fragments into a beam that can then be decelerated to generate power. The rate the particles decelerate at depends on their energy; as a consequence, the deceleration process also can help provide isotopic separation as an automatic reprocessing stage.
A magnetic mirror induced by an axial magnetic field is used to concentrate fragments into a beam that can be slowed down for power generation. The rate at which particles slow down depends on their energy, and this process also helps in separating isotopes automatically as part of the reprocessing stage.
