Inertial electrostatic confinement
Inertial electrostatic confinement is a branch of fusion research which uses an electric field to heat a plasma to fusion conditions. Electric fields can do work on charged particles (either ions or electrons), heating them to fusion conditions. This is typically done in a sphere, with material moving radially inward, but can also be done in a cylindrical or beam geometry. The electric field can be generated using a wire grid or a non-neutral plasma cloud.
