content: Just wanted to make a short post about a couple of items inbound to the lab, really to solicit thoughts about what to do with them other than scrapping & recycling them. If you have any ideas, let me know. Of course i will make some kind of video on them whatever happens so let me know if you want long and detailed videos or just a quick disassembly?So we have two Brucker NMR (Nuclear Magnetic Resonance) Superconducting magnets coming in, they were both used on a DRX500 NMR machine, one seems to be complete, the other has been partially disassembled. They use liquid helium and nitrogen for the cryogenics. Of course i am mostly interested in seeing the solenoid magnet and the superconducting wire but everything i am sure will prove interesting.We also have arriving in a couple of weeks, two large rapiscan baggage x-ray machines, similar to the one mikeselectricstuff featured on his channel a few years ago but bigger. no idea if they are working or not or even if they are complete.It'll be at least a few weeks before much happens

content: You have some interesting gear land on your doorstep.Almost feels like Dave's mailbag - but yours would come in a 3 ton truck.

content: Time to take some packs of that superconductor wire and send to Dave, will at least make a nice picture in a frame.

content: Teardown? I'd be looking for liquid nitrogen firstThough I'm not sure your neighbours would be too impressed to have their cutlery flying across the kitchen and embedding itself in the walls.

content: Quote from: SeanB on August 08, 2017, 06:22:48 pmexcellent idea, one of the magnets is partially disassembled. The previous owner cut one open with a plasma cutter!It means we'll be recycling at least that one. So we should have lots of what is probably Nb-Ti wire.Quote from: CJay on August 08, 2017, 07:38:54 pmit's actually liquid helium and nitrogen!Quote from: Gyro on August 08, 2017, 07:49:31 pmThanks for the note, one has been almost entirely disassembled, what the previous owner was doing with it i have no idea but the other looks untouched. Apparently unused for years so i doubt there is any pressurised liquids remaining, but we'll check first.

content: Always wanted to see one of those babies taken apart.There's only so much that can be discerned from random photos off the net.Any change you also got the power supply for the magnets ?

content: thanksthe large magnet has been sold as a complete item, but the one that's been partly torn apart i am hoping to pull some of the wire out of but we don't really know how it's all been assembled under the outer wrapping which looks like some resin impregnated fabric... ie is the wire encapsulated, glued etc underneath this covering?I must admit even the magnet that's partially disassembled is still amazingly heavy and is complete with razor sharp edges where the steel casing has been cut openi think the wire will probably just look like copper magnet wire due to it's construction but i did wonder if people might be interested in lengths of the wire? it's not the sort of thing you get your hands on every day
