Sommario:
- <p>This white paper proposes a <strong>multilayer hybrid shield</strong> (“Real Force Field”) that can be built and tested with 2025 components. Layer 1 is an <strong>electrostatic/ion-wind curtain</strong>: a 6–10 kV corona emitter and 1–3 kV collector form an invisible barrier that charges and drifts aerosols toward washable plates, assisted by a low-power jet (U ≥ 1.5 m s⁻¹ at < 15 W). We enforce <strong>ozone-safe operation</strong> via in-line O₃ sensing and AC+KMnO₄ cartridges, with a unified acceptance limit <strong>ΔO₃ ≤ 10–20 ppb</strong> at the outlet. Layer 2 is a <strong>compact magnetic bubble</strong> for charged-particle deflection: a multi-turn <strong>REBCO</strong> ring (r ≈ 0.5–1 m) designed by <span><span>B=μ0NI/(2r)B=\mu_0 NI/(2r)</span><span><span><span>B</span><span>=</span></span><span><span><span>μ</span><span><span><span><span><span><span>0</span></span></span><span></span></span></span></span></span><span>N</span><span>I</span><span>/</span><span>(</span><span>2</span><span>r</span><span>)</span></span></span></span> with <strong>NI ≈ 0.32–0.64 MA-turn</strong> to reach <strong>B ≈ 0.2–0.4 T</strong> in the lab; fields and currents are mapped by <strong>magneto-optic (KCR) sensors</strong> with lock-in readout. Layer 3 is a <strong>transient plasma skin</strong> that darkens incident laser energy (≥ 20 dB attenuation in a closed test cell). Residual mass/impacts are handled by a <strong>Whipple-style bumper</strong> (CNT-foam + Al₂O₃ tiles). We detail <strong>KPIs and Go/No-Go gates</strong>: ΔPM₂.₅ ≥ 50–70% across a 1 m aperture; U ≥ 1.5 m s⁻¹; ΔO₃ within limit; magnetic map <span><span>R2≥0.97R^2 ≥ 0.97</span><span><span><span><span>R</span><span><span><span><span><span><span>2</span></span></span></span></span></span></span><span>≥</span></span><span><span>0.97</span></span></span></span>; plasma attenuation ≥ 20 dB. Safety covers HV creepage/EMC, interlocks, and laser protocols. The contribution is a <strong>reproducible, open-hardware pathway</strong>—BOMs, equations, CSV/QA.json schemas, and SOPs—so other groups can validate, improve, or repurpose the stack for environmental, industrial, and space-systems use.</p>
