@claudiop63 How do they (you) manage to cool down the magnets to 1.9 Kelvin and keep the temperature stable ?

Hi. It takes a lot of liquid helium, which incidentally is itself in a funny state (superfluid) :-).
@aramus thanks! I have just watched this video, the guy nailed it down ;-) Very good explanation of quantum mechanics and quite an entertaining one - mix helium 3, helium 4, pour in a U - tube, then use the same technique as with vodka distillation to bring helium 3 up, and the mixture sucks the temperature on the border between the two liquids.
