Superconducting NMR magnets

Refilling the Liquid Nitrogen jacket of the superconducting magnets at work. Water mist so fine, Rayleigh Scattering makes it look blue. (or is that Tyndall Effect?) Next: b-field pattern stands my wire cutters on end.

So, what IS your work ?

[wbeaty]

Electronics nerd, in the UW chem dept.

> the electromagnetic radiaton like aged him 30 years in 30 seconds.

No, it's the eating dry ice that does it.

[stefanmckinley]

Oh yeah! that's cool!

IN THE FIRST CLIP HE HAD HAIR!

the electromagnetic radiaton like aged him 30 years in 30 seconds.

see! science is EVIL....EVIIIIL i say!

burn him!!! burn the witch! :)

It's Rayleigh scattering.

HOW DO THEY WORK!?

[weezilla]

Typically, the spin states of protons (aka, hydrogen, +1/2 or -1/2) are equal in energy. The standard kind of proton NMR puts out a strong magnetic field, which creates forces on proton spin states so that they separate energies instead of being equal. Once the energies are "split," the NMR can send radiation through the molecules. Hydrogens in different types of molecules are split by different amounts, and absorb the frequencies based on how much they are split.

I like your work :)

Ln2 filling the dangerous way - using plastic hose. It can split when frozen - should use stainless steel braided hose instead.

u think ur gonna get a +1 ? xD

The cobwebs in some electric motors are the same as I find in my house. They are not done by spiders. Are we living in some kind of plasma field?
