Development of an Analysis Tool for Filtering and Classification of ProtoDUNE Time-Structured Database Payloads*

The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation experiment that will use a powerful beam of neutrinos, originating at Fermilab in Illinois, and a large, 10 kton-scale detector located a mile underground in Lead, South Dakota. The ProtoDUNE detectors are large-scale prototypes for DUNE, designed to test and validate the technologies that will be used in the full DUNE far detector. The Slow Controls (SC) database system is used to monitor thousands of detector systems, such as high voltage, temperatures, and purity, in real-time. The SC data, or metadata, which is sampled and stored at a rate of between 1 and 10 hertz, is a vast volume of time-series data. We have developed a tool to analyze and characterize the metadata stored in the SC database. In this talk I will describe the SC analysis tool and describe how it is currently being used, and will be used in the future.
