Hi Dave,
Email me, I have plans. It uses an x ray transformer.
You need a disc of tempered glass.

Esteemed Group,
With Halloween nigh upon us, I was thinking of more interesting
things to possibly build for next year.
Does anyone know anything about the circuitry for Ken Strickfaden's
Lightning screen? I know there is a central disc electrode that
arcs to a peripheral ring. I suspect the disc surface is smooth glass.
Phosphorescent paint (inaccurately called "radioactive" paint in the
1943 Popular Mechanics article) applied behind the glass results in
afterimages of the discharges.
I'm trying to figure out if the unit is driven with AC or DC, or AC
with a capacitor across the output. I'm guessing AC, but don't know
if there was any capacitance across the supply.
Has anyone built one? Anyone ever have the chance to examine the
original article?
