I can also tell you that most people that wind up learning this stuff themselves don’t learn things properly. For example, we have a number of HV possible vacuum chambers, but the gaskets going from the chamber are rubber and not copper. I mean, why spend so much freaking money on a chamber that can go to 10^-8 mbar when you’ve got a rubber gasket on there that can only go to 10^-3!?!
