VIC design session v18: best candidate (Q=26.2, 326.8kHz)
Sweep: Prior L sweeps (0.15-2.5mH) with 3-4 parallel cells never landed f_r in-band; test unexplored 0.02-0.15mH low-L region plus 2.5-5mH high-L region, both at Q-preserving high-turns/low-AWG config, to bracket the 40-70kHz target from both sides
Cell: 9mm rod in 13.0mm tube × 100mm, 1 cell(s) parallel → C_eff = 1.19nF, bulk water R = 12014Ω. Water/electrodes (Randles): 2ppm Na+ @ 25°C, surface ×1 → λ_D 53nm, C_dl 21.9µF, cell series R 14.1Ω, displacement current 96.7%, breakdown margin ×380. Chokes: 2 × 0.0001H (80 turns, AWG 20, 10m wire, AC R 0.8Ω each). At resonance f_r = 326.82kHz: Xl = 411Ω, Xc = 411Ω, tank Q = 26.2, coil Q = 251.1. Cell voltage 314V from 12V drive (×26.2), series current 764.8mA. VIOLATIONS: resonance 326.8kHz outside practical 1-100kHz band Score 0.291.
