Hi everyone,
Our building management wants to do a full 4h emergency power shutdown for maintenance. This is NOT a real/serious problem if your magnets are not subcooled magnets. It's just a real pain because you need to warm-up your CryoProbes, fully shutdown the spectrometers, loose a day dealing with this and hope that when the emergency power is restored all the instruments will come back up with no problem.
But this message is more intended to NMR managers with subcooled magnets because now it is serious business and we need to keep pumping the magnets no matter what.
Of course we have a UPS for each 800MHz spectrometers. One of the 800MHz has a relatively new UPS but the other 800MHz has a 3 years old UPS and we can't trust it to last that long. We can't even be sure that their maintenance will only last 4h anyway. The solution I am aware of at the moment, is to use a very powerful generator (renting one $$$) to keep pumping the magnet but I was wondering if anyone with subcooled magnet(s) already had to deal with long period of emergency power shutdown and how did you handle it?
Any feedback will be greatly appreciated.
All the best,
Genevieve
