WFC design session v11: best candidate (Q=67.6, 100.0kHz)
Sweep: Hold adopted choke design fixed; sweep rod/tube gap and length around adopted geometry to raise water resistance and tank Q without collapsing capacitance, and test paralleled cells vs single cell
Cell: 21.8mm rod in 26.8mm tube × 60mm, 1 cell(s) parallel → C = 1.27nF, water R = 90535Ω. Chokes: 2 × 0.001H (130 turns, AWG 18, 16m wire, AC R 0.6Ω each). At resonance f_r = 99.97kHz: Xl = 1256Ω, Xc = 1256Ω, tank Q = 67.6, coil Q = 1096.4. Cell voltage 812V from 12V drive (×67.6), series current 646.1mA. All constraints satisfied (current <1A, band, wire length). Score 0.727.
