Magneto-inertial fusion and field-reversed configurations
The pulsed middle ground between magnetic and inertial confinement.
Magneto-inertial fusion sits between the two mainstream approaches. Magnetic confinement holds a steady plasma at low density; inertial confinement compresses a tiny target very fast. Magneto-inertial fusion compresses a magnetised plasma on an intermediate timescale, using the embedded magnetic field to suppress heat loss during the implosion, so the density and confinement-time trade sits in a different, pulsed regime.
A natural target is the field-reversed configuration: a compact toroid with closed field lines and no central column, which can be formed, translated, and then compressed. Around it sit the pulsed-power drivers and liner-compression schemes that deliver the implosion, and the diagnostics and triggers that must fire on nanosecond timescales.
This is the physics of the merge-and-integration-fabric studio, whose published work targets deterministic phase synchronisation and sub-50-nanosecond FPGA trigger synthesis for high-beta pulsed plasmas — the control and timing problems specific to this pulsed regime rather than to a steady tokamak.
