Mmm, a few hundred pounds of liquid He.

Here's a crappy video I took last week while we were filling an MR magnet. Care to guess what's dripping?

Helium also plays a critical role in cooling down large magnets (MRI, NMR, particle accelerators) which is part of the reason why warmer super conductors are needed. I know most of the big research institutions have a helium scavenging process to minimize loss.

These machines are greedy SOBs. We have used the equivalent of about 3 million liters of helium gas keeping just 1 instrument cooled at work over the past 9 years. They are now selling a version that doesn't require the liquid helium to cool it.

It blows my mind helium balloons still exist when there's such a finite supply of helium and how important it is to medical equipment. It's really quite absurd and a fine example human shortsightedness.
Don't **** with people's benefits and childhood.

The machines aren't greedy. 4K is freaking damn cold.
