Neutral-Beam Injector
Fires energetic neutral atoms to heat the plasma and drive current.
- Role
- Heating + current drive
- Lead time
- ~24 mo
A neutral-beam injector accelerates ions, neutralises them, and fires the resulting fast atoms into the plasma to heat it and drive current, within HYPERION's 25.9 MW auxiliary budget. It is a specialised, long-lead component.
A neutral-beam injector accelerates ions, neutralises them, and fires fast atoms across the confining field to heat the plasma and drive current, within HYPERION's 25.9 MW auxiliary budget. High-energy beams use negative-ion sources and are specialised, long-lead components of the heating system.

High-energy beams use negative-ion sources and are specialised, long-lead components, but they are demonstrated technology on existing machines rather than an open research question.
