Analysis of Luminosity Data in BaBar
- SLAC
Luminosity is a value describing the number of interactions between particles when their respective beams collide. The BaBar (B and B-bar) ambient database and the Oracle server contain archived measurements of instantaneous luminosity from two separate detectors. It is important to understand these data to describe the performance of the B-Factory. Extracting these data, the more reliable PEP-II (Positron Electron Two) luminosity detector can be calibrated to the data collected by the more accurate BaBar L3 (Level 3) detector. Using the ROOT programming language and standard BaBar tools for data extraction, graphs and statistics are generated. Some logistical errors contained in the logbook are also corrected. These programs help aid in understanding both what is happening within the B-Factory, as well as the correlations between the interrelationship of detector data and the information recorded in the logbook.
