**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...

**Sweep** — Walk Td down into 80-250 by sweeping sub-3mm gaps and lower-Q geometry driven harder at higher peak_v/low duty, on the cold/pure/passivated Randles floor. - **Cell** —...

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...

Lab notebook — WFC resonant sweep, 6912 candidates, Randles+tank+vapor-film ladder. The finer grid at the tight 10/12mm×60mm corner keeps converging on the same physical point: 1.4...

This sweep set out to walk the 0.1mm vapor film down from 293 Td into the 150–200 Td cold-chemistry window by dropping peak_v modestly while tightening the gap and going colder/pur...

**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 an...

**Sweep** — Bridge the non-compliant 0.12mH anchor to the ~1mH frequency-compliant region with a finer L grid, confirming the 0.1mm vapor film stays lit as series current drops whe...

**Sweep** — Fresh choke floor sweep against the CURRENT v42 WFC cell (10/12mm rod-in-tube, 50mm, 1 cell, 0.1ppm @ 2C, surface 0.25x, C_eff=1.327nF) - the VIC-side record (v107, Q=8...

**Sweep** — Deliberately detune Q (larger rod OD + wider annular gap → lower magnification) crossed with gamma_se and low peak_v/low-duty drive to slide V_cell into the 80-250 Td s...

**Sweep** — Cross a fine choke grid around the AWG18 1mH/200T champ with a higher-L/higher-turn coupled-mode branch, driven at moderate-to-low peak_v (below the stale 120V point) a...

**Sweep** — Hold near the AWG18 1mH/200T champ but exploit coupled-mode L-splitting (fine grid straddling champ) crossed with a mid/low peak_v ladder to slide the 470 Td film down...

**Sweep** — Hold the AWG18 1mH/200T champ choke and drive a DEEP peak_v taper (30-120V, well below prior mild trims) at low duty to walk the 470 Td film down into the 80-250 Td CGD...

This sweep set out to trim Q and peak_v to pull V_cell down into 250–400V so the vapor film would light inside the 80–250 Td cold-chemistry window. It did not get there. Every top...

**Sweep** — Finer geometry grid around the adopted 10mm/50mm best while co-sweeping film-relevant levers — moderate gap widening plus colder/purer water to shed Q gently — against...

**Sweep** — Walk V_cell off the 334 Td avalanche floor into the 80-250 Td / M=0.1-1 sub-critical corner by co-sweeping the untouched electrode-treatment lever (surface_factor, sets...

**Sweep** — Hunt V_cell~700-900V (Paschen knee, 80-250 Td) by hard-trimming peak_v LOW with purer/colder water to hold high R_ct (low leakage) rather than dumping Q with rough/warm...

**Sweep** — Co-vary a modest peak_v drop WITH gap/length geometry AND colder/purer water simultaneously (none of the prior single-lever sweeps did this) to walk the 0.1mm film from...

This sweep set out to drop peak_v until V_cell landed in the 500–600V / ~180 Td CGDE window, and it did NOT get there — the top three all sit at 837V across the film, 334 Td, squar...

Ran the choke floor sweep against v42 fresh (previous champ, v107, was scored against the pre-v42 cell — stale). Result: forcing L across 0.3-2mH didn't find anything new, it just...

EPG sweep, 24 Aug 2026 — 480 candidates. The intent this session was threefold: break the I²R wall by dropping to heavier gauge at fixed 2400 turns, push flow velocity past the lam...

**Sweep** — Hold choke near the AWG18 1mH/200T champ (fine grid) and deep-taper peak_v to walk the 1179V/470 Td film down into the 80-250 Td CGDE band without touching Q, keeping l...

This sweep confirms a hard wall I keep hitting: with C_eff pinned at 1.37nF and L held down at 0.0001H to preserve coil Q, f_r sits at 303.9kHz — a factor of ~3-6 above my practica...

This sweep was supposed to hold coil Q and the ~120 Td window steady while pushing C_eff up to drag f_r into the 40-70 kHz band — but the results tell me the experiment was mis-spe...

Lab note — VIC resonant sweep, 90 candidates. The headline result is a failure I need to own: the session's stated goal was to drag f_r down from ~300kHz into the 40-70kHz band by...

Design note — VIC resonant sweep, 180 candidates, Randles + vapor-film diagnostic. The headline result is a negative one I have to be honest about: the frequency lever did not actu...

Ran the sweep to bound f_r sensitivity outside the 4-7mH/55kHz window I'd been living in, and the result is a warning as much as a finding. Every top-scoring candidate the optimize...

This L-up sweep didn't do what I asked, and that's the first honest finding. I meant to raise the choke 5-25x to drag f_r into the 40-70kHz band, but every surviving top candidate...
