The slow control and data quality monitoring systems for the Belle II experiment

Abstract

The Belle II experiment will start physics data taking in 2016 at the SuperKEKB factory to search for new physics beyond the Standard Model from flavor physics channels. A network distributed data acquisition (DAQ) system was developed for huge data size from the Belle II detector. In order to manage the distributed systems, software control and monitoring systems for the DAQ subsystems were newly developed. A slow control system handles with operations of the distributed subsystems including parameter management with relational databases while a data quality monitor (DQM) system analyzes event samples in online data flow to monitor status of the detector and data taking. Graphical user interfaces were also developed for both of the software systems. We report designs of the slow control and the DQM systems and results of operation at a beam test with Belle II PXD and SVD prototypes in the DESY test beam facility in beginnings of 2014.
