Dumb question
Brumby:
I can appreciate that - but we have a very wide range of personalities. From grumpy old codgers to the quiet and reserved. You also have to watch out for communication issues that can arise from cultural backgrounds and non natives of the English language. This is a true global community.
While people rarely set out to be offensive, sometimes a point is made quite strongly and, on occasions, it can be useful to have a thick skin.

A quick search for voltage multiplier modules returns dozens of inexpensive results with voltages that go far beyond anything you could want.
But here, as everywhere, numbers are your friend. The can supply only tiny currents at these voltages. How much current does your io izer need? Multiply your proposed current and voltage to get the power consumption. Something tells me you are asking for a lot of power. (A lot is contextually defined, but here means more than must voltage multipliers are designed to provide)

A CW ionizer uses micro Watts. Maybe even Nano Watts. They use insanely little power.

At a fixed frequency, the emf is (2 pi)x(f)x(peak flux). The linked flux is the cross-section area multiplied by the (flux density = B field), multiplied by the number of turns. For typical iron alloys, the B value at core saturation is about 2 Tesla. That limits the AC voltage on the winding: if the transformer is designed to handle 120 V on a primary winding (5 x N turns), it cannot handle 120 V on a winding of only N turns.
I wish it were easier to enter equations here.

You can use LaTeX for equations
\$ V=\sqrt{2}\cdot \pi\cdot f\cdot N\cdot \phi_{max} \$

Years ago I took apart an ionizer. It used a CW multiplier connected directly to the 120VAC input and feeding a needle for the output. There was no transformer in it at all. Seems like it had about 15 stages but I couldn't swear to it, it's been a long time.
