The capillary tube caught fire. Below is the picture of the setup.

Here is gif file of the fire.

I used same brand power supply. And voltage was just 4KV on both sources.
I did not connect the pulser circuit for this initial test.

Can you please point out the problem, I spent a so much resources on this project.
Thanks

Please consult with someone familiar with high voltage electronics. This looks dangerous. There is no time when current for the high voltage applied to this system should exceed a single digit mA. A bbq lighter is a good place to start to generate some ions. https://www.amazon.com/Rechargeable-Electric-Flexible-Flameless-BBQ%EF%BC%88Blue%EF%BC%89/dp/B07PKS6D8K?th=1
