    Sweet!
    When will you be able to mount the STM?

    It's the one that is being protected by the hoist.

    We just have to adjust all the pieces around it now.

    (BTW a student punched himself in the face and cut his lip this morning while tightening a flange)

    It(stm) doesn't look the same as the last time I saw it. Mwah!

    Does anybody but me remember the other "Big Red"?

    Here is my "Big Red" even though it is more Blue...

    For some reason, when I tried to add the picture, it posted it elsewhere and not here.

    Well, I appear to be making a mess of this orderly site.

    Daniel, can you post a "Cliff Notes" description of what that is supposed to do and would I want to build on in the barn for fun?

    Do I see vacuum fittings? WTF is that thing?

    Email a larger picture, if you have the time.

    on=one

    It makes a vacuum close to that of deep space so that we can study really, really clean surfaces.

    You could put one in the barn to impress neighbors

    We do something similar with the vacuum chambers on the magnets.
    So you have a roughing pump and a molecular turbine pump? How many Torr do you draw down to?

    So its a roughing and turbo initially. We then valve that off (too noisy) and pump with an ion pump and a titanium sublimation pump.

    The base pressure ought to be less than 1x10-10 torr.

    What magnets are you talking about? MRI magnets?

    Yes. We use a vacuum chamber as insulation for the liquid helium vessel. MRI magnets are really just multi-walled thermos bottles.

    We are happy with something in the "ten to the minus 8 or 9 Torr" range as far as vacuum..

    Ion pump sounds cool and a titanium sublimation pump makes the pee drizzle down the inside of my leg.

    I don't see any cryogenics. Soak that bad boy in liquid nitrogen and see what it does.
