Radiation resistant magnet R&D for FRIB nears successful completion at Brookhaven National Laboratory

Friday, January 13, 2012

The complete set of high temperature superconductor (HTS) coils have been assembled onto their support structure and tested at Brookhaven National Laboratory (BNL).

The coils of the first quadrupole magnet in FRIB's fragment separator region must withstand an intense level of radiation and accommodate a very high heat load. The quadrupole magnet coils are built from stainless steel tape containing strips of the  superconducting material YBCO (named for its constituent elements yttrium, barium, copper, and oxygen). While previous superconducting magnet designs often used epoxy or some other plastic as an insulator, the stainless steel chosen by Brookhaven engineers will stand up to the radiation produced at FRIB’s production target.

At Brookhaven National Laboratory, the complete set of HTS coils are assembled for testing at 77 K (about -320 degrees Fahrenheit) which will complete R&D.
