Abstract

The silicon vertex tracker at the BABAR experiment is the primary device used in measuring the distance between B0 and B0 meson decay vertices for the extraction of CP asymmetries. It consists of five layers of double-sided, AC-coupled silicon modules, read out by custom integrated circuits. It has run well consistently for eight years. I report on three years of experience in managing problematic bias leakage currents in the fourth layer. In addition, I report on recent success in decreasing the data acquisition time by reducing the readout window.
