Magnetic Confinement Design.

Problem.

Tokamaks dominate fusion research due to their demonstrated plasma stability, but they inherit fundamental limitations: large physical scale required for adequate confinement time, complex superconducting magnet systems, pulsed operation requiring periodic shutdown for current drive, and geometric constraints that make maintenance access difficult. The dominant question is not how do we optimize the tokamak but which of these constraints are fundamental physics, and which are artifacts of historical development.

Approach.

First-principles analysis of magnetic field topology requirements for stable plasma confinement. Rather than starting from existing reactor designs and optimizing parameters, the approach begins with the physics constraints (pressure balance, MHD stability criteria, particle and energy confinement) and systematically explores what field geometries satisfy those constraints.

Investigation areas.

• Steady-state field configurations — eliminating pulsed operation and the need for current drive systems.
• Compact confinement geometries — reducing reactor scale while maintaining adequate confinement time.
• Alternative coil topologies — simplifying magnet systems and improving maintenance access.

Specifications.

Status.

Active theoretical investigation. Constraint formulation complete; topology search in progress. Output is paper-form rather than prototype at this stage.
