Every headline number regenerates from a named script and archived data under a fixed random seed; requirement-class assumptions and open risks are carried openly rather than absorbed into a single optimum. Each paper below has its own page, linking the manuscript to its data-and-code deposit, the interactive 3D model, and the live verification simulator.
The complete volume
The Kronos 2026 Publication — Complete Volume
All five studies in one bound volume: the compact fusion isotope-and-energy platform, front to back — breeder, generator, magnets, direct energy conversion, and AI/quantum control — with the shared methodology, notation, and reproducibility manifest that ties them together.
Breeder · Spherical Tokamak
P. I. Ford, G. L. Kulcinski · Kronos Fusion Energy
A compact spherical-tokamak breeder whose size is set by an isotope-supply requirement rather than by electrical output. Across 25,200 configurations the minimum plasma current meeting a national tritium duty falls to 4.93 MA — a third of ITER's — and tritium breeding is presented as an openly-shown blanket lever (demonstrated beryllium-multiplied TBR ≈ 1.34, with an advanced-blanket development target above it). Helium-3, the strategic product, is bred independently of the blanket.
Generator · D–³He Tandem Mirror
P. I. Ford, G. L. Kulcinski · Kronos Fusion Energy
A low-neutron D–³He generator that closes its power balance on measured component efficiencies, with every extrapolation beyond demonstrated hardware named rather than hidden. Introduces a new physics result — the synchrotron effective harmonic cutoff scales with machine size — and states its single largest open requirement (end-plug density) plainly, including a companion structural gate on the plug winding.
Magnets · REBCO
P. I. Ford, R. J. Weggel, C. Weggel · Kronos Fusion Energy
A strain-first REBCO conductor architecture and a bore-resolved winding method, applied across two dissimilar machines. The central result is an honest negative: the binding constraint flips between a stress-comfortable spherical-tokamak centrepost and a stress-bound mirror plug, with the field a conductor enables kept rigorously separate from what a coil can realise. Kronos has fabricated and measured nothing; every number is a design target, model output, or literature inference.
Power Conversion · DEC
P. I. Ford, G. L. Kulcinski · Kronos Fusion Energy
Shows that the conventional framing of advanced-fuel direct energy conversion describes the birth spectrum, not the axial loss channel: at reactor temperatures the recoverable stream is a directed electron flow that no published converter recovers. Proposes a quasineutral two-species expander — the ambipolar magnetic nozzle run backward — with a pre-registered bench program to test it.
Control · AI & Quantum
P. I. Ford · Kronos Fusion Energy
A layered, AI-native digital-twin control architecture evaluated as a methods-and-certification study, holding three technology-readiness tiers strictly apart. Demonstrates a deterministic safety clamp (3000/3000 injected violations caught, zero escapes), a certified control-barrier guarantee preserved through calibration, and a quantum-inspired kinetic solver — while reporting every missed target rather than reframing it.
Reproducibility. Each deposit is Open Access (CC BY 4.0) in the Kronos Fusion Energy Zenodo community and carries a run-all reproduction driver, pinned computing environment, and per-file checksums. The papers contain no financial or commercial information.
