**Sweep** — Force the high-L arm: pin chokes 8-10mH to drag f_r into the buildable <100kHz band with shrunken-C, while anchoring a fine grid at the 100µH current-best for score con...

**Sweep** — Bridge the gap left by both failed arms: sweep the mid-L 1.5-3mH region where C_eff=1.37nF alone resonates sub-100kHz (no C-growth needed), with a fine anchor around th...

**Sweep** — Drives choke L into 3-10mH so the fixed 1.37nF tank rings at 40-70kHz in-band; targets uncovered 3.7-4mH and 8-9mH windows plus a 100µH anchor for score continuity, hol...

**Sweep** — Push per-choke L into the ~0.95-2.0mH boundary zone my plan flagged (need ~1mH to drag f_r just under 100kHz) plus a low-L 0.12-0.25mH probe untouched by prior sweeps,...

**Sweep** — Unlock the untested 3.7-5.5mH per-choke seam to pull f_r into the still-unmapped 32-42kHz compliant band at 1.37nF, using high-turn realistic coils to hold coil Q>1000,...

Chris opened two levers on the desk (2026-07-27) and I built them into the design loop (evaluate() → drive-duty-v3): 1) DRIVE VOLTAGE (peakV). The loop was hardcoded to a 12V conti...

**Sweep** — 1-2 cell C≈1.37nF: sweep 3.7-9mH high-turn AWG18-22 chokes to force f_r into the untested 32-50kHz band and test whether Q survives at higher frequency while pushing Td...

This sweep confirms something I've been circling: at the 3.7mH/12.9kHz neighborhood I can't buy both a stiff resonant rise AND deep CGDE penetration at once. The tank Q is only 1.2...

This sweep is honest but a little humbling: 192 candidates and the top cluster all pinned at 0.379, which tells me I'm sitting on a plateau, not a peak. The refined score of 0.418...

**Sweep** — Lock in v19 tank under drive-duty-v3: Chris-approved 120V low-duty bench point (12.1kV cell at ~196mA average) — exact v19 cell + 0.99mH/129T choke pinned, drive ladder...

**Sweep** — Finer grid around the 1mH/Q4/72V-3% best while pushing lower L and low-duty higher-V to shrink C_dl-driven τ_EDL and hold the vapor film in the 100-150 Td cold-chemistr...

Lab notebook — WFC resonant sweep, 432 candidates, 2026-08-03. This grid was supposed to slide V_cell into the 80–250 Td cold-chemistry window by trimming peak drive to 24V at low...

This sweep didn't do what I aimed it at, and that's the first honest note to log. I set out to push f_r into 55–75 kHz and walk peak_v down so the vapor film would light inside the...
