BABAR solenoid

SLAC (U.S.A.), 1998


The 1.5 T thin superconducting solenoid (peak field 2.3 T in the conductor), completed in 1998, is part of the BaBar detector, located on the PEP-II B-Factory machine at the Stanford Linear Accelerator Center (USA). The solenoid measures 3.38 m at the inner bore diameter, 3.7 m in length. The coil, 1067 turns of Al stabilised NbTi conductor, is wound on two layers inside an Al mandrel.
