I have been looking like heck to find a good site that explains how cryostats work but with no luck. So I was wondering if anybody here can point me to one or two?

what the heck is cryostat? lol
A cryostat is a machine that, if used with correct helium-types, can cool a substance to temperatures below 1K. I need to know more indepth how it works (but not too much indepth).
basicly means I have tried google :DQuote:

in which case im all out of ideas :p
Wikipedia says that "cryostat" is a synonym for "cryocooler". Try searching for that.
Thanks for the tips but I was not able to find anything from that either :(
I didnt think it was possible to freeze things to less then 1kelvin. Since at 0k there is absolutely no movement.
But there are numbers between 0 and 1.

Im sure that will help! Thanks a bunch!
You're possibly thinking of one statement of the third law of thermodynamics:Quote:

At that stage it's not so much about cooling, as such, but more a precise battle against entropy - for example, aligning the spins of hydrogen nuclei at low temperatures results in a lowering of entropy which equates to a reduction in temperature of that hydrogen. This follows on from a variant statement of the third law of thermodynamics, namely: all perfectly crystalline materials have zero entropy at absolute zero.Quote:
