VIC design session v109: best candidate (Q=24.5, 94.6kHz)
Sweep: Walk peak_v DOWN from bench-proven 120V while holding the AWG18 1mH champ (plus two slightly softer chokes) to drag the 470 Td film back into the 80-250 Td CGDE band and re-score the leakage-robust loaded point.
Cell: 24mm rod in 28.0mm tube × 50mm, 1 cell(s) parallel → C_eff = 1.41nF, bulk water R = 30097Ω. Water/electrodes (Randles): 0.5ppm Na+ @ 25°C, surface ×0.5 → λ_D 106nm, C_dl 6.7µF, cell series R 47.0Ω, displacement current 96.2%, breakdown margin ×114. Fig-8 voltammetry (4,798,661): τ_EDL 200324.4µs (18953.2 carrier cycles to charge), Faradaic leakage at peak 111.8mA (leak score 0.48 — keep amp leakage inhibited while voltage climbs the ladder). Vapor-film discharge (CGDE onset, 1101V across 0.1mm film): regime townsend-avalanche, film Paschen 778V, 439 Td — OUTSIDE the 80-250 Td cold window. Townsend α/γ: γ = 0.003 (electrode lever), criterion M = γ(e^{αd}−1) = 1880.725 → self-sustaining (M≥1) — γ feedback closed, heading for thermalization. Per-molecule (series micro-capacitor chain): 7.41M molecules across 2.00mm → 148.64 µV/molecule (polarization (µV band)). Chokes: 2 × 0.001H (180 turns, AWG 18, 21m wire, AC R 0.8Ω each). At resonance f_r = 94.61kHz: Xl = 1189Ω, Xc = 1189Ω, tank Q = 24.5, coil Q = 767.2. Cell voltage 1101V from 45V drive (×24.5). Tank current 0.93A circulating (CW upper bound — rate wire/switch for this); average input 19mA at 2% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.612.
