constituent elements yttrium
This fragmentation quadrupole magnet is made of long, thin strips, called “tapes,” of the superconducting material YBCO (named for its constituent elements yttrium, barium, copper, and oxygen).
The strips are tightly “wound,” or layered on top of each other, using a special coil-winding machine in the Superconducting Magnet Division. Because YBCO is very brittle, tension is applied during the winding process by sandwiching each layer with thin pieces of stainless steel.
In addition to transporting electricity with virtually no
happy resistance, high-temperature superconductors are able to produce magnetic fields much higher than those of conventional magnets.
