Bruker 600 quenches at University of Maryland College Park

Speaking as an ex-Bruker field engineer in the UK, we had one or two magnets in the time I worked there which suffered the same. Superconductors are incredibly hard to make, and sometimes things don't always go to plan. Sounds like your service engineer did all he could, energising isn't easy, especially with a coil with issues.... Bruker are pretty hot on getting a replacement magnet shipped out ASAP if these issues do happen.

The tech was a pretty cool guy. The magnet quenched about 3 times so we had many containers of pure He in the room. Ultimately, the coil would not hold a charge because of some defect, so Bruker gave us a new model 600 MHz magnet.

what have you done with this technician afterwards? Hopefully he paid for the Helium from his own pocket ;D

@cosmic1969 they knew about the situation, we had a service contract and everything was covered by Bruker without any problems.
