The second generation BaBar RPCs: Final evaluation of performances

Over 200 second generation RPCs were installed in the Forward Babar region in the summer of 2002. They have fulfilled their task in an honorable fashion although they always needed a lot of attention and special care. Some region of them has integrated a charge in excess of half a C/cm(2). Their behaviour over time will be reviewed in this paper together with the corrective action applied to the system to preserve it. (C) 2009 Elsevier B.V. All rights reserved.
