# IX-StellaratorForge
**Evidence-driven stellarator fusion reactor design and computational co-design program.**
IX-StellaratorForge preserves the original `IX-Fusion` research lineage and builds the reactor-level program above it. The first reference architecture is **SFR-1 Rev A**.
> **Release:** `0.4.0 — SFR-1 Maximum Computational Closure`
>
> **Current verdict:** `MAXIMUM_IN_REPO_COMPUTATIONAL_CLOSURE_COMPLETE__PRODUCTION_SOLVER_AND_HARDWARE_GATES_REMAIN`
>
> SFR-1 is a preconceptual computational reactor program. It does **not** claim a demonstrated fusion reactor, ignition, tritium self-sufficiency, net electricity, or construction readiness.
## What v0.4.0 resolves
v0.4 turns the remaining red-X list into explicit executed calculations or production-solver jobs. It does not rename a surrogate as high fidelity.
| Problem | v0.4 result |
|---|---|
| Failed fixed coil basis | **Resolved as rejected.** Two new architecture classes are executed: classical helical TF+helix co-design scans and a continuous winding-surface current-potential reconstruction. Neither earns promotion. |
| G1 equilibrium | **Input-generation problem closed; production solve open.** Four finite-pressure VMEC-family seed files are generated from the exact analytic SFR-1 screening boundary for DESC/VMEC++ execution and cross-check. |
| G3/G4 confinement | **Requirements/topology quantified; kinetic validation open.** Q=10 confinement requirement and vacuum field-line transform/nestedness are executable; alpha-orbit, neoclassical and gyrokinetic production evidence remains required. |
| G2 HTS magnets | **Geometry screen executable; magnet qualification open.** Curve length, bend radius and conservative REBCO hard-way strain proxy are calculated; field-performance failure prevents promotion and winding-pack Ic/FEA/quench/manufacturing qualification remains mandatory. |
| G7 neutronics/TBR | **Source and geometric breeding bounds closed; full 3-D transport open.** Exact D-T source/tritium ledgers and blanket-coverage constraints are calculated; an OpenMC CSG torus proxy builder and 3-D statepoint analyzer are included. |
| G8 net electric | **Conditional plant equations closed.** The current ~704.57 MW uniform screen gives ~204.10 MWe under the declared plant assumptions; the 300 MWe floor requires ~913.04 MW fusion; the 1 GW target ledger gives 340 MWe. |
| Actual net-electric fusion | **Not computationally resolvable.** It requires physical hardware and calibrated measurements. |
## Current numerical snapshot
At the current 8.0 m major radius, 1.7 m minor-radius screening geometry, 6 T axis field, 3% beta and 15 keV uniform D-T screen:
- screened fusion power: **704.57 MW**;
- fusion power required to clear the 300 MWe plant floor under the existing plant assumptions: **913.04 MW**;
- corresponding fixed-temperature uniform-beta screen for that net floor: **~3.415% beta**;
- beta screen for the 1 GW target: **~3.574%**;
- current screened net-electric algebra: **~204.10 MWe**;
- 1 GW target net-electric algebra: **340 MWe**;
- current best simple classical-helical vacuum architecture: **4FP, alternating helices, 0.40 helical/TF current ratio**; it retains the nestedness screen but produces only **~0.0389 mean iota**, so it fails the transform requirement;
- continuous winding-surface current-potential held-out RMS `Bn/B0`: **~1.64% (2FP), 2.32% (3FP), 3.05% (4FP), 4.57% (6FP)** — all fail the 0.5% screen;
- the geometry-only REBCO strain proxy is below the 0.4% ceiling for the screened TF/helical centerlines, but that is **not** winding-pack qualification.
These numbers are evidence at their stated authority only. A failed reduced/intermediate screen can reject an architecture; a passing reduced screen cannot prove a reactor.
## High-fidelity execution pack
The repository contains exact fixed-boundary finite-pressure seed inputs:
- `external_solvers/inputs/input.SFR1_QA_2FP_REF`
- `external_solvers/inputs/input.SFR1_QI_3FP`
- `external_solvers/inputs/input.SFR1_QI_PWO_4FP`
- `external_solvers/inputs/input.SFR1_C6_QI_6FP`
and executable adapters:
- `external_solvers/adapters/run_desc_equilibrium.py`
- `external_solvers/adapters/run_vmecpp_equilibrium.py`
- `external_solvers/adapters/build_openmc_axisymmetric_proxy.py`
- `external_solvers/adapters/analyze_openmc_3d_tbr.py`
- `external_solvers/adapters/validate_production_receipt.py`
The adapters **stop** if the real dependency is unavailable. They never silently replace DESC, VMEC++ or OpenMC with in-repo surrogate physics.
## Run the in-repo campaign
```bash
python scripts/run_computational_closure.py
python scripts/generate_v040_evidence.py
python check_stellarforge.py
```
The first command is the expensive deterministic architecture campaign. The release gate validates its tracked evidence rather than repeatedly recomputing the same field scan in several subprocesses.
## Reactor envelope
| Item | Rev A value | Authority |
|---|---:|---|
| Major radius | 8.0 m | reference-informed target |
| Minor radius | 1.7 m | design target |
| On-axis field | 6.0 T | reference-informed target |
| Volume-average beta | 3.0% | screening/design point |
| Fusion-power class | 1,000 MW | design target |
| HTS operating temperature | 20 K | reference-informed target |
| Maximum field on conductor | ≤20 T | design ceiling |
| Plasma-to-coil distance | 1.35 m target; 1.20 m hard floor | design constraint |
| Full-3D TBR | ≥1.15 target; 1.10 hard floor | production-solver objective |
| Thermal conversion efficiency | 40% target | plant target |
| Recirculating-power ceiling | 120 MW | design target |
| Net-electric floor | 300 MW | design requirement, not prediction |
No core is privileged: 2FP QA reference, 3FP QI, 4FP QI/piecewise-omnigenous, 6FP C6 lineage and a direct-J assumption-breaker remain competitors.
## BOM / design inventory
`BOM/SFR1_FULL_SYSTEM_BOM.csv` and `.md` contain **87 unique system-level rows** spanning plasma, magnets, cryogenics, vacuum, PFCs, blanket/shield, tritium/fueling, RF, diagnostics, controls, heat transport, power conversion, electrical, maintenance, safety, facility and solver infrastructure.
“Full” means complete at the system-architecture inventory level. It is **not** falsely labeled a procurement/fabrication BOM: final quantities, nuclear compositions/enrichment, conductor sizing/current, pressure ratings, safety setpoints, vendors, part numbers and drawings remain solver/hardware dependent.
## Evidence gates after v0.4
1. **G1 equilibrium — production execution open.** Inputs are complete; real finite-beta DESC and VMEC++ convergence/cross-code evidence has not been executed in this build runtime.
2. **G2 coils — new architectures executed, no promoted set.** Low/intermediate tests reject current fixed boundary/coil combinations; true plasma/coil co-optimization, REBCO Ic/strain over winding packs, loads/support FEA, tolerances and quench remain open.
3. **G3/G4 confinement — requirements and vacuum topology quantified, kinetic transport open.**
4. **G5 edge/divertor — open.**
5. **G6 RF — resonance-scale screen retained; 3-D deposition/wall-plug closure open.**
6. **G7 neutronics — source/coverage bounds complete; full 3-D OpenMC/DAGMC transport open.**
7. **G8 system — conditional algebra closed; coupled prediction waits on G1–G7.**
8. **G9 hardware — open by definition.**

`IX-STELLARATORFORGE: GREEN` means the release, tests, PoC, BOM, license, tracked computations and solver contracts reproduce. **It never means fusion was achieved.**
