“A mine I used to work in used methyl mercaptan as part of their emergency alert system. When there was a situation that required everyone to t report into the refuge chambers underground, a 10lb bottle of this stuff was dumped into the fresh air supply for the mine. I felt sorry for the person who had to release it.” From https://www.youtube.com/watch?v=_iLOd9fPkXo via Dangerous Chemistry thread.

Mercaptan is also the odorizing agent added to natural gas. That stuff is concentrated nasty, so much so that in a prior cyber security job, we dreamed up multiple attack scenarios that focused on mercaptan specifically. I'm not sure what happened with that proposal.

Or are they still intensely magnetic even without the helium supercooling them? I'm surprised those guys got their ratchet straps(?) out in that video with so few hands. Thought I remembered seeing a video where like a 10lb weight on a cable is held taught in mid-air several feet back from the device.

They don't shut it off by turning off the electricity, they shut it off by dumping the liquid helium so it warms up above its critical temperature and loses its superconductivity. Only then does the circuit start burning off the electricity through resistance. So shutting it off isn't a particularly practical operation.

My understanding is that a quench is a "we do this maybe once or twice over the entire life of the unit" kind of thing- very carefully supervised rare occasions (like "we are moving the MRI unit to another hospital") or an emergency situation only.

MRI magnets are gigantic slabs (some up to 30 tonnes!) of magnetized iron bent into a precise shape. There is no turning them off, they aren't electromagnets. An electromagnet of the strength needed to be used for that kind of imaging would probably gently caress with other things, and also use enough power to run a small town. Oh yeah and the MRI magnets have to sit in tanks of liquid helium to keep them cold enough to work properly, that's the other big part of the problem. There's a reason MRI scans are expensive even if you cut through all the insurance bullshit. Fajita Queen fucked around with this message at 04:44 on Jun 29, 2022 |

and helium doesn't just grow on tree ya know it requires a second generation star to compress and knock hydrogen together and then go supernova to disperse the newly formed atoms. which is hard to come by these days

I thought some MRIs are permanent magnets, and some are electromagnets (which are the ones needing helium).
