Good afternoon (here in Europe). I have an x-ray tube I want to isolate. I was planning to use a good epoxy resin I got from RS. The cathode is grounded so the anode will be working at 60kV, and I'm worried about the anode itself heating, expanding and pushing the epoxy towards the tube & cracking it, see picture.
I know there are some x-ray users here that are much more experienced than me, I would really like to avoid a liquid isolator, I have this epoxy with a dielectric strenght of 12kV/mm and it is indicated for applications where there are different materials with different expansion coefficients.
