The Börekçi Solar Antimatter Collector v5: A Quantitatively Self-Consistent Architecture for Harvesting Solar-Flare Positrons with a Plasma-Magnet Magnetoshell, Flare-Ambush Targeting, and Multicell-Trap Storage

Archival version note: This record archives version v5 (July 2026) of the Börekçi solar antimatter collector concept. It supersedes v4 (Research Square preprint, DOI 10.21203/rs.3.rs-10177321/v1) and is itself superseded by v6 — "The Börekci Solar Antimatter Collector v6: A Liouville-Limited, Plasma-Magnet-Free Architecture that Closes on Demonstrated Trap Technology" (Zenodo, DOI 10.5281/zenodo.21798248) — which replaces this version's plasma-magnet magnetoshell with a plasma-magnet-free architecture. Readers seeking the current design should consult v6; this record is published for version-history transparency. Abstract (v5): The Sun is the most powerful natural producer of antimatter in the Solar System: RHESSI gamma-ray spectroscopy implies that a single large flare creates of order 5×10²⁹ positrons (≈0.5 kg of antimatter), and the physics of tenuous plasmas guarantees that any positrons which escape into the outer corona and solar wind survive against annihilation for years to millennia. Version 4 of this concept proposed a Sun-diving cycler that funnels escaping positrons into Penning–Malmberg traps and returns them to Earth orbit. This paper (v5) subjects v4 to a quantitative audit, identifies ten deficiencies, and rebuilds the architecture around a plasma-magnet magnetoshell collector with flare-ambush targeting and multicell-trap storage.
