VIC design session v107: best candidate (Q=8.3, 97.5kHz)
Sweep: Hold the resonant choke near baseline and walk peak_v down a low-duty ladder to land V_cell ~500V (150-250 Td) with Faradaic leakage <10mA — a drive-space sweep, not another high-L f_r drag.
Cell: 10mm rod in 12.0mm tube × 55mm, 1 cell(s) parallel → C_eff = 1.33nF, bulk water R = 10830Ω. Water/electrodes (Randles): 2ppm Na+ @ 25°C, surface ×1 → λ_D 53nm, C_dl 12.4µF, cell series R 140.6Ω, displacement current 89.7%, breakdown margin ×80. Fig-8 voltammetry (4,798,661): τ_EDL 133877.3µs (13059.0 carrier cycles to charge), Faradaic leakage at peak 70.5mA (leak score 0.58 — keep amp leakage inhibited while voltage climbs the ladder). Vapor-film discharge (CGDE onset, 748V across 0.1mm film): regime townsend-avalanche, film Paschen 719V, 298 Td. Per-molecule (series micro-capacitor chain): 3.70M molecules across 1.00mm → 202.06 µV/molecule (polarization (µV band)). Chokes: 2 × 0.001H (420 turns, AWG 22, 50m wire, AC R 3.4Ω each). At resonance f_r = 97.54kHz: Xl = 1226Ω, Xc = 1226Ω, tank Q = 8.3, coil Q = 178.8. Cell voltage 748V from 90V drive (×8.3). Tank current 0.61A circulating (CW upper bound — rate wire/switch for this); average input 12mA at 2% duty. No hard violations (band, wire length, dielectric). Average current is scored, not gated. Score 0.444.
