Robert Bussard Polywell (Navy-Funded, EMC2, WB-6/WB-7/WB-8, Beta-One Conditions, p-B11 Aneutronic)
01 Executive_Summary
ASSESSMENT: Robert Bussard developed the Polywell (Wiffle-Ball) concept under Navy funding via EMC2 (Energy/Matter Conversion Corporation, Santa Fe, NM). Combines electrostatic fusion + high-beta magnetic cusp confinement. Polyhedral arrangement of magnetic coils creates point-cusp confinement. 'Wiffle-ball' = high-beta plasma fills cusps, trapping particles. ACHIEVED BETA-ONE CONDITIONS (β = 1) — plasma pressure = magnetic pressure. Conventional tokamaks NEVER reached β = 1. WB SERIES: WB-6 (~2005-2006, 30 cm coils, Bussard 'Should Google Go Nuclear' talk Nov 2006). WB-7 (~2008-2009, 30 cm, partial magnetic insulation, 5×10^11 cm^-3). WB-8 (2009-2015, 40 cm, full magnetic insulation, 50 kV, 3×10^12 cm^-3 (6x WB-7), β=1 achieved). WB-8 CONTRACT: Naval Air Warfare Center Weapons Division, China Lake. N68936-09-0125. WB-8 improvements: externally held coils, arc plasma source, 2 kA @ 50 kV, 8 electron injectors (10A/gun), 1 MW ion injection via NBI. KEY RESULT: 'β=1 plasma were achieved with strong diamagnetism and good stability.' BUSSARD p-B11 REACTOR: 'Aneutronic fusion is the holy grail.' 'Non-Maxwellian plasma energy distribution.' 'Break-even reactor was 13m diameter.' 'Bremsstrahlung losses found manageable.' Patent: 20110170647 (2006 application). CRITICAL: Polywell = polyhedral cusp confinement = orb's internal structure (per Forbes). Navy-funded = same branch as Pais patents. β=1 = high-beta = compact form factor. p-B11 = aneutronic = no neutron signature. Program went quiet after 2015 — completed or transitioned to classified. 2025 arXiv paper (2508.06761) 'Polywell Revisited' discusses EMC2 suspension of R&D.
