Description
Summary:We report on our progress in the development of the technology for the application of Bi 2 Sr 2 CaCu 2 O 8+x (Bi-2212) in Wind-and-React accelerator magnets. A series of superconducting subscale coils has been manufactured at LBNL and reacted at the wire manufacturer SWCC. Selected coils are impregnated and tested in self-field, even though the coils exhibited leakage during the partial melt heat treatment. Other coils have been disassembled after reaction and submitted to critical current ( Ic ) tests on individual cable sections. We report on the results of the current carrying capacity of the coils. Voltage-current ( VI ) transitions were reproducibly measured up to a quench currents around 1400 A, which is 25% of the expected performance. The results indicate that the coils are limited by the inner windings. We further compare possibilities to use Bi-2212 and Nb 3 Sn tilted solenoid, and YBa 2 Cu 3 O 7-delta (YBCO) racetrack inserts to increase the magnetic field in HD2, a 36 mm bore Nb 3 Sn dipole magnet which recently achieved a bore magnetic field of 13.8 T. The application of Bi-2212 and/or YBCO in accelerator type magnets, if successful, will open the road to higher magnetic fields, far surpassing the limitations of Nb 3 Sn magnet technology.
