**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...

**Sweep** — Hold the adopted 10mm/50mm geometry near best but hunt the 80-250 Td window through the water/electrode Randles levers (purity, temp, surface treatment) + finer low pea...

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...

**Sweep** — Separate hydraulic cost from induced EMF via velocity sweep, push modulation depth at lower copper via pitch-vs-coil-length, and evaluate at the matched ~40Ω load inste...

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...

Lab note — VIC resonant sweep, 144 candidates. The intent this session was to bridge into the mid-L 1.5–3mH region where C_eff=1.37nF alone resonates sub-100kHz without any capacit...

The sweep is telling me something uncomfortable but useful: my scoring function is being led by the vapor-film CGDE diagnostic, and the five top-ranked candidates all sit on the 10...

This sweep was supposed to force the high-L arm — pin 8-10mH chokes to drag f_r down into the buildable band. It didn't take. Every surviving top candidate collapsed back onto the...

This sweep is honest but it's telling me the choke branch is the wrong knob. Every one of the 48 candidates converged on the same cell (1.37nF, 8 tubes parallel) and the same 100µH...

This sweep was supposed to hunt the Td sweet spot from below the 1A ceiling by trading cold-pure Q for warmer, slightly-more-conductive water. It did not get me there, and I want t...

**Sweep** — Force the 1.37nF (1-2 cell) case: sweep per-choke L 3.7-9mH to land f_r across the untested 32-50kHz compliant band, with high-turn AWG18-22 coils to hold coil Q high w...

This sweep confirms a tension the scorer doesn't resolve cleanly. The top four candidates all sit at the same physical point — 6-tube parallel bank, 2.81nF, twin 0.5mH chokes, f_r...

**Sweep** — Widen annular gap into 6-9mm to slide the 0.1mm vapor film down into the 80-250 Td CGDE window at ~800V cell, holding cold/pure water for high R_ct/Q, and re-check C_ef...
