A High dielectric strength insulator

  • Thread starter 1Keenan
  • Start date

I would need advice on insulator material I can use for an ion Thomson Parabola spectrometer.
I would need to use an insulating sheet of 225x600x1,5mm and a smaller sheet of 100x100x1,5mm

I found PBN having an incredible dielctric strength, but seems like it cannot be manufactured in sheets bigger that 100x200 mm with proper flatness
MIca seems to be good as well and easier to produce, but I cannot find a supplier selling it with dielectrict strenght higher than 30kV/mm. In literature it is reported something like 100kV/mm and sometimes even more.

DO you have any suggestions?

THank you in advance
