Database utility and SiPM leakage current studies for sPHENIX physics data-taking

The sPHENIX detector, at the Relativistic Heavy Ion Collider (RHIC), was designed to study hard probes of the quark-gluon plasma. To this end sPHENIX handles data, in the hundred petabyte range, obtained from the collisions of high energy nuclear matter annually. Storing, sorting, and processing this data is crucial to achieving the scientific goals of the sPHENIX program. We develop software, using databases in a number of ways, to track the conditions of the sPHENIX detectors sub-systems throughout the course of data-taking, and to provide a repository of physics-quality data for offline analysis. This poster will present the database tool we developed to maintain lists of good data runs for physics analysis. As one specific aspect of the monitored detector conditions, this poster will also present our studies on SiPM leakage currents in the calorimeters to quantify the effect of radiation on the detector.
