anomaly detection and data quality monitoring for spinQuest target and detector systems

SpinQuest will measure the sea quarks Sivers asymmetry, with a target transversely polarized with respect to the incoming 120 GeV proton beam. The Sivers asymmetry describes the distribution of the unpolarized quarks inside a polarized nucleon. SpinQuest will explore the properties of the nucleon's spin composition by investigating the correlation of the light antiquarks motion relative to the nucleon spin. An online monitoring system has been developed to scan the polarized target system data stream and polarization data while integrating information from detectors and event reconstruction for near-continuous quality checking of the incoming data. Online monitoring of the target system and detector package will play a vital role in ensuring optimal performance to obtain the highest figure of merit possible given the experimental circumstances. This novel monitoring system enhances the debugging process during commissioning and data acquisition through the use of machine learning pattern recognition techniques and anomaly detection. This scheme promises to aid target operators and shift takers during the two-year-long production runs to begin in Fall of 2023 at Fermilab.
