WFC design session v22: best candidate (Q=62.1, 329.3kHz)
Sweep: Fixed #1 geometry: sweep choke-adjacent proxy via water_ppm extended higher and surface_factor combos not yet tried, while checking if cell voltage stays within 80-250 Td Paschen window as R drops
Cell: 9mm rod in 17.0mm tube × 100mm, 1 cell(s) parallel → C_eff = 0.58nF, bulk water R = 77724Ω. Water/electrodes (Randles): 0.1ppm Na+ @ 60°C, surface ×0.25 → λ_D 250nm, C_dl 1.1µF, cell series R 8.8Ω, displacement current 98.9%, breakdown margin ×319. Vapor-film discharge (CGDE onset, 745V across 0.1mm film): regime townsend-avalanche, film Paschen 719V, 297 Td. Chokes: 2 × 0.0002H (180 turns, AWG 22, 21m wire, AC R 2.3Ω each). At resonance f_r = 329.26kHz: Xl = 828Ω, Xc = 828Ω, tank Q = 62.1, coil Q = 183.0. Cell voltage 745V from 12V drive (×62.1), series current 900.0mA. VIOLATIONS: resonance 329.3kHz outside practical 1-100kHz band Score 0.346.
