01
Gate 1 — freeze the comparison
Record orbit, geometry, material inventory, spectra, scoring volumes and mission duration. Include a no-field case and a passive-only case at equal installed mass. Predeclare success and stop criteria before searching for an attractive geometry.
02
Gate 2 — verify field and particle calculations
Check field solvers against analytic coil cases and measured maps. Check trajectory integration against a uniform-field helix and demonstrate convergence with step size. Include relativistic momentum where necessary. Cross-check representative cases using an independent implementation.
03
Gate 3 — calculate dose, not just deflection
Use a validated radiation transport framework to account for interactions in coils, supports and station materials, including secondaries. Report uncertainty and locations where dose increases as well as decreases. A particle animation or magnetic-rigidity calculator cannot close this gate.
04
Gate 4 — separate the physical experiments
Measure field topology and particle deflection with a controlled source and calibrated detectors at a suitable test facility. Test optical and thermal coupons separately. A low-energy beam demonstration does not validate cosmic-ray protection; declare exactly which species and energy range each test covers.
05
Gate 5 — close the installed system
Compare thermal, electrical, structural and failure budgets with the baseline. Require external technical review before an uncrewed demonstrator is considered. Crew safety must not depend on experimental shielding. Present status: literature-grounded concept and analytical teaching tool; no shield prototype, radiation-transport result or measured ARLO dose benefit.

We are defining a research scope for radiation transport, superconducting engineering and optical-material testing. No shield is offered for sale or operational use.
