A link to the experiment. some British profs were also involved, although they actually only used 10 Tesla.
The strongest of the current RU electromagnets can go up to 38 Tesla (they have various others) but they have had to reduce the number of experiments due to the electricity bill, even then they are building a 45T magnet!
Het HFML heeft 20.000.000 Watt vermogen beschikbaar voor de magneten, vergelijkbaar met het energieverbruik van ongeveer 10.000 huishoudens. Om die capaciteit veilig en gelijkmatig aan te kunnen voeren, heeft het gebouw een eigen aansluiting op het hoogspanningsnet. Tijdens het gebruik van de magneten warmen hun koperen platen razendsnel op. De watercentrale en koelinstallatie zorgen voor continu koud water dat met 140 liter per seconde door kleine gaatjes in de magneet stroomt, om te voorkomen dat de platen smelten.
The HFML (high field magnet lab) has 20 000 000 Watt (20MW) available for the magnets, equal to the energy use of 10 000 houses. So that this much electricity can be fed (to the magnet) in a controlled fashion, the building has its own direct connection to the high voltage grid (50 000V). [it is transformed down to 500V AC and then rectified to DC for the magnets]
During the use of the magnets their copper plates heat up very fast. The water pumping station and cooling installation ensure that continuous cold water at 140 m/second (at pressure of 25 bar (!)(!)) flows through small holes in the magnet, to prevent the copper plates melting. [The hot water thus created is also pumped round the rest of the University building and used for heating]
