Fusion Energy

How these connect

Tokamak (toroidal magnetic confinement) and what it relates to. Every line is an evidence-backed relation, and the arrangement is fixed — this address draws this picture, today and next year.

  1. Tokamak (toroidal magnetic confinement) · must_satisfy · Fusion triple product (n·T·τ_E)

    A tokamak reaches useful fusion power only when density, temperature and energy confinement time simultaneously satisfy a Lawson-type triple product threshold.

  2. Tokamak (toroidal magnetic confinement) · requires · Tritium

    Deuterium-tritium is the only fuel mixture whose reaction rate is accessible at temperatures current machines can reach, so every near-term power concept consumes tritium.

  3. Tokamak (toroidal magnetic confinement) · requires · Deuterium

    Deuterium supplies the other half of the deuterium-tritium fuel and is abundant in ordinary water.

  4. Tritium · constrains · ITER

    ITER's deuterium-tritium phase draws on the same finite, decaying civil stockpile that every other tritium-burning project draws on.

  5. Joint European Torus (JET) · informs · ITER

    JET's DTE3 campaign tested operating scenarios and tritium-handling procedures explicitly intended as input to ITER.

  6. Stellarator · alternative_to · Tokamak (toroidal magnetic confinement)

    Both are magnetic confinement concepts; the stellarator produces its twist from external coils and so does not depend on a driven plasma current.

  7. ITER · confines_by · Tokamak (toroidal magnetic confinement)

    ITER is a tokamak, confining its plasma with a toroidal field plus a field generated by current driven through the plasma.

  8. Joint European Torus (JET) · confines_by · Tokamak (toroidal magnetic confinement)

    JET was a tokamak and holds every deuterium-tritium fusion energy record set by magnetic confinement.

  9. EAST (Experimental Advanced Superconducting Tokamak) · confines_by · Tokamak (toroidal magnetic confinement)

    EAST is a superconducting tokamak operated for long-pulse high-confinement studies.

  10. SPARC · confines_by · Tokamak (toroidal magnetic confinement)

    SPARC is a compact high-field tokamak using high-temperature superconducting magnets.
