Abstract

A 1.5 T thin superconducting solenoid has been in operation as part of the BaBar detector since 1999. This magnet is a critical component of the BaBar experiment. A significant amount of magnet operating experience has been gathered. The average availability of this magnet currently approaches 99 percent. This paper describes the historical frequency and modes of unplanned magnet ramp downs and quenches. It also describes steps that have been taken to mitigate these failure modes as well as planned future improvements.
