    The nickel mesh acts as an insulator and more heat will exit both ends of the vessel (as opposed to going through the middle of the vessel having no mesh inside). I haven't yet figured out how much the mesh changed my calibration constant for the vessel…

    I found this for the LHC ... note the low temperatures which means the outgassing is much reduced:
    A vacuum thinner than the interstellar void
    Ultra-high vacuum is needed for the pipes in which particle beams travel. This includes

    do you agree with this guess: It wasn't a leak in the thermowell or at the weld of the thermowell but it was the high temperature of the thermowell that outgassed lots of gas. In other words, the thermowell gets much hotter than…
