48 seconds at those temperatures is no joke, that is pretty amazing. I didn’t see the article elaborate on what the current limiting factors are for pushing beyond 48 seconds. Like I wonder if it’s a hard wall, a new engineering challenge, a tweak needed, etc. this is the reactor that set the last record so they are doing something really right.
They most likely ran out if liquid helium as the world is running out of the stuff at an alarming rate
This is such a ridiculous comment. I can literally go on Amazon and buy some helium right now. You really think if that's possible, a cutting edge research lab would run out of the stuff?
Sure, it's limited and getting scarcer, but no one's running out yet.

You're obviously an idiot

That doesn't mean that they didn't have enough. The world being in the process of losing helium as a whole doesn't mean these researchers "ran out" of it. If they knew they needed it, they would have purchased it, so unless the world has run out of helium already then they didn't run out of it. You act like noone there could calculate exactly how much helium this uses per second and just buy x seconds worth of helium.
OK let me rephrase, they ran out of usable liquid helium. You do realise LH is the coldest known substance known. If you have 5L of usable LH once you use the 5L and turn it into a gas it is no longer -254c A sing use of an MRI uses 2000L at say the low end of cost of $30 so $60,000 and that is at room temps now add a few thousand degrees....
A single use of an MRI doesn't use 2000 liters, that is the upper end of a hospitals ENTIRE supply of helium. On average an MRI users 70 Liters per MONTH of operation. You're literally just spewing bullshit at this point, have a fun time being completely misinformed on things that upset you greatly, I'm going to go play games
You are right. In a sense, they have to reclaim the helium. It takes 2,000L to run it, they reclaim it compress/cool then reuse it. That 70 L/month is what they loose after use.
Do some reading before being an ass
