Abstract :
A superconducting final focusing system for the KEKB B-Factory was constructed and has been operating since 1998. It consists of two solenoid field compensation magnets, two final focusing quadrupole magnets, and three kinds of correction coils (normal and skew dipoles, and skew quadrupole). The system has been operating without any serious problems and its total operating time has reached 17,000 hours. This paper describes the details of the system and operating experiences gathered during the long-term operation
