Electromagnetic analysis of beams for the ITER ECH Upper Launcher
Four Electron Cyclotron Upper Launchers (UL) will be used in ITER to inject power at 170 GHz, mainly for suppression of MHD instabilities, especially Neoclassical Tearing Modes. For each UL, the quasi-optical section injecting millimetre waves into the plasma consists of eight be...

Nonlinear gyrokinetics of the compact spherical-tokamak breeder at the frozen negative-triangularity design point. Nonlinear CGYRO with kinetic electrons shows negative triangularity cutting ion-scale (ITG+TEM) transport by 40-45 percent versus a positive-triangularity twin, with...

Thermal-Barrier Decoupling - The Cornerstone Plug Mechanism
The plug's electrostatic potential is the burner's binding gate. A thermal barrier — a local density/potential depression sustained by ECH hot electrons and sloshing ions — decouples the plug potential from the central-cell electrons: the ion-confining-potential requirement drops...

A Control-Barrier-Certified Zero-Escape Safety Clamp for a Compact Spherical-Tokamak Breeder
A deterministic, control-barrier-certified safety clamp providing a provable zero-escape guarantee for the compact spherical-tokamak breeder operating envelope. A robust, disturbance-tightened control-barrier-function filter with a closed-form separable solution wraps an arbitrar...

A reduced-order assessment of disruptions, runaway electrons, and electromagnetic loads for the compact spherical-tokamak breeder, on a NIMROD-verified equilibrium. Current-quench time 7-19 ms; a SEVERE runaway-electron avalanche (E/E_c about 1128, a beam of order 70 percent of p...

The Tritium Fuel Cycle and Breeding Ladder of a Compact Spherical-Tokamak Breeder
The tritium fuel cycle and breeding ladder of a compact spherical-tokamak breeder, developed as an honest mass balance. The per-unit burn rate follows from the fusion power; the net surplus is a confirmed ladder to the advanced-blanket ceiling. A single advanced unit exports trit...

Fast-Ion and Alpha-Particle Confinement in a Compact Spherical-Tokamak Breeder
Fast-alpha and fusion-product confinement in the deuterium-helium-3 tandem-mirror burner. The mirror-trapped charged products and their loss-cone dynamics set the ash accumulation and the axial power that the direct-energy-conversion and alpha-channeling systems must handle. Repo...

Licensing a Compact Fusion Platform Under the Byproduct-Material Framework
Licensing a compact fusion platform under the United States byproduct-material framework (10 CFR Part 30), confirmed for fusion by the 2023 NRC determination and the ADVANCE Act. The materials-oriented, Agreement-State-administrable, graded path suits a machine whose only signifi...

The Tensor-Network Kinetic Solver - Classical, Deployable Today
The kinetic distribution function is highly compressible in a low-rank tensor-network representation, and that yields a practical classical solver, not a storage trick. On a 1D1V BGK test, a matrix-product-state truncation reaches relative-L² error 2×10−⁴ at rank 8 using ~0.19× t...

The drift-cyclotron loss-cone (DCLC) microstability of a deuterium-helium-3 tandem-mirror plug. A flute-mode electrostatic dispersion solver, cross-checked electromagnetically, maps the exact marginal-stability boundary. The design's warm-ion fill sits exactly on the stabilizatio...

A reduced-order red-team of the binding gates of a compact spherical-tokamak breeder and a deuterium-helium-3 tandem-mirror burner. For each honest negative, alternatives are brainstormed, bounded, ranked, and only the promising ones promoted to high-fidelity validation. The curr...

The integrated Kronos platform as one architecture: a compact negative-triangularity spherical-tokamak breeder supplying tritium, helium-3, neutrons, and isotopes, and a deuterium-helium-3 burner supplying power at a low neutron fraction, sharing a REBCO magnet basis and a single...

Isotope Co-Production and 14\,MeV Materials Qualification at a Spherical-Tokamak Breeder
Isotope co-production and 14 MeV materials qualification at the spherical-tokamak breeder. The same fusion-spectrum source provides a high-flux materials-qualification volume many times the reference dedicated facility, and breeds shortage-prone medical isotopes such as molybdenu...
