I Vacuum chamber pressure calculation in TOKAMAKS

  1. Apr 26, 2016 #1
    Hello all!

    I understand the concept of the TOKAMAK vacuum chamber, but can someone explain to me how I can actually calculate the pressure in which I need the chamber to be evacuated? I know it should be in the range of approximately 10^-7 or so but more specifically, is there an equation to calculate the actual number?

    Thank you in advance.

    Better will work better, and different tokamaks will use different pressures. Did you check the publications?

    I've searched online in PDFs and some, related to my question, publications but I couldn't find anything besides general information regarding vacuum and its typical values for a tokamak. I didn't find anything regarding a calculation process.
