When I'm not making YouTube videos, I'm growing crystals in a Molecular Beam Epitaxy vacuum chamber held about 12 orders of magnitude below atmospheric pressure. This is the first in what I'm hoping will be a series of videos featuring the MBE chamber, and this time I'm talking about leaks: how to find the tiniest leaks in the most sensitive systems, and how an MBE can be considered basically a perfect pressure vessel with no air leaking in or out at any time. Let me know in the comments if you have any questions about the MBE I could address in future videos!
