Spear2 RF operation: a bridge to Spear3

The present schedule calls for Spear2 RF system operation until March of 2003, when it will be dismantled to make room for the Spear3. While any new investment to improve the system is discouraged for this limited-time operation, efforts are focused on maintaining the system reliability and accommodating any changes necessitated by new construction in preparation for the Spear3. In this paper we will present our operational experience with the changes incorporated into the system. The Booster RF system improvement to raise the injection energy from 2.3 to 3.0 GeV will be also discussed.
