Lab note — CGDE-window sweep, Randles floor. This run was supposed to walk the vapor-film field down into the 80–250 Td cold-chemistry window by shrinking the gap (sub-3mm) and dri...

This sweep tried to light the vapor film from the water side — drop gap, chill to 4°C, and run 0.2ppm ultrapure so a modest drive lands in the cold-chemistry window — and it expose...

This sweep was supposed to hunt the 700-900V Paschen knee and land the vapor-film in the 80-250 Td cold-chemistry window. It didn't quite. Every top candidate lands at ~886-901V ce...

All five top candidates are effectively the same cell and choke; only duty separates #1–#4 (2/4/8/15%) and #5 swaps to a 620-turn choke. That degeneracy is itself the finding: the...

Lab note — WFC resonant sweep, surface-treatment as the fresh lever. The finer grid confirms the 10mm-in-12mm × 60mm cell as the sweet spot: C_eff 1.58nF resonating my 0.9mH chokes...

This sweep set out to walk peak_v down to land V_cell near 500V, 150-250 Td, with Faradaic leakage under 10mA. It did not get there — and that's the honest headline. Every top cand...

**Sweep** — Finer grid at the 10-12mm×60mm best but use surface_factor as the fresh lever to raise C_dl and hold displacement current while low peak_v + cold pure water crush leaka...

**Sweep** — Hold the AWG18 1mH/200T champ with a fine choke grid and walk peak_v down from bench-proven 120V to land the 470 Td film inside the 80-250 Td CGDE band via lower magnif...

**Sweep** — Map the untouched 0.1-1mH transition between the physics-ideal 100µH reference and the buildable 1mH floor at high-Q gauges, to see where film lighting decays as L clim...

Ran the 32-50 kHz seam hunt, but honesty first: the optimizer ignored my intent. I asked for 1-2 cells (C_eff ~1.37 nF) to push f_r up into the 32-50 kHz band; every surviving cand...

This sweep pins the v19 tank (1.29nF cell, 0.99mH/129T choke) and walks the drive ladder, so Q, f_r, and voltage magnification are all frozen at Q=101.2, f_r=99.41kHz, ×101.2 gain....

This sweep set out to pin the 150 Td cold-window from the density side, and I'll be honest: it didn't get there. Every top candidate lands at 572 Td (1434V film) or 1144 Td (2868V)...

Lab note — annular-gap widening sweep, 7776 candidates. The stated goal was to slide the 0.1mm vapor film down into the 80–250 Td cold-chemistry window by opening the gap to 6–9mm...

Sweep note — VIC vapor-film tuning, 1440 candidates at resonance. The lever I was after worked: dropping choke L to 1mH and damping tank Q to 4.0 pulls V_cell down to ~288V, and th...
