Cockroft Walton voltage multiplier

A cockroft walton voltage multiplier is a circuit that increase the input voltage.
The circuit is made by stages and each stage is made by 2 diodes and 2 capacitors.
Here is a schematic of a 2 stages voltage multiplier:

I used IN4007 diodes and some high voltage capacitor that I found in a printer power supply circuit; however i reccommend ceramic capacitors with low capacitance and about 3kv of max voltage.
Here are some photos of mine 8 stages, 5kv, cockroft walton multiplier:

Here is a video:
