This invention relates to a fusion reactor of the magnetic mirror type having a plasma trap defined by relatively widely spaced field lines, and end regions closed substantially by said field lines. Plasma leakage from the trap occurs primarily through the end regions inasmuch as the plasma particles tend to follow the field lines instead of moving transversely thereto. Electrostatic reflectors serve to reflect particles that have escaped from the plasma trap via the end regions back thereinto along the escape paths, these electrostatic reflectors taking the form of positively and negatively charged field-forming electrodes arranged in tandem such that positively charged plasma particles will be reflected by one electrode and negatively charged particles will be reflected by the other. |
