Homemade High Frequency "XRT"
Mr.Warwickshire, Fri Jul 07 2017, 05:18PMI have just wound a flyback transformer with an insane turn count, much like the high frequency inverter xray transformers. I will immerse in pure mineral oil and keep it under vacuum for a day (Around -620 Torr). Then I will "fire" it up on first my half bridge then my in progress flyback mode driver. I made sure to keep the wire traveling to the next section of the bobbin spaced far enough away from the high potentials at the top. I have had great success with my lower turn count paper insulated flybacks so I hope this turns out the same.
Here are some pictures of the "XRT" flyback:
Here's a picture of my low turn count (Around 1600 turns) flyback while being wound. I believe this was the fourth layer.
Anyways, I will be posting more as things come along.
:D

That coil looks really good, but 'Insane' turns count does not say much, an accurate, ballpark or even just estimated count would have been much better. Wire diameter too would have been nice.
You could make up for these omissions by measuring the self resonant frequency of the coil, and posting that.
Just my ten cents.

I am using 32awg wire on the coil. If I had to estimate I would say somewhere around 4000+ turns. I sadly have no way of measuring the resonant frequency. I need to buy a scope!

Project Update:
SUCCESS!
With my flyback mode driver I was able to get some incredible voltages especially considering I am using 32awg wire (huge compared to normal XRT's). It was atleast 40kV HF EHT! The arcs would jump like 5cm to the ground wire! Not only was it high voltage but when I cranked the input voltage up to around 40v, the arcs were thick white arcs! With a multiplier I could easily achieve 300kV! My goal is to arc HF 300kV. This tempts me to make another coil like this but using 44 awg wire....MUCH MORE TURNS!. Heres some pictures!:
