Use of ROOT in the D0 online event monitoring system

PDF Version Also Available for Download.

Description

The D0 experiment is one of the two High-Energy proton anti-proton collider experiments at Fermilab, USA. Since the detector serves multiple physics purposes, it consists of many different sub-detector systems together with supporting control systems. Therefore, online event monitoring plays a crucial role in ensuring detector performance and data quality by parasitically sampling events during the data taking. ROOT, a physics analysis package developed at CERN, is used in the D0 online monitoring as the main analysis tool, providing a graphical user interface that interacts remotely with an analysis executable and tools to monitor informative histograms as they get updated ... continued below

Description

The D0 experiment is one of the two High-Energy proton anti-proton collider experiments at Fermilab, USA. Since the detector serves multiple physics purposes, it consists of many different sub-detector systems together with supporting control systems. Therefore, online event monitoring plays a crucial role in ensuring detector performance and data quality by parasitically sampling events during the data taking. ROOT, a physics analysis package developed at CERN, is used in the D0 online monitoring as the main analysis tool, providing a graphical user interface that interacts remotely with an analysis executable and tools to monitor informative histograms as they get updated in shared memory throughout the data taking. In this paper, the authors present the basic structure of the D0 online monitoring system and the use of ROOT in the system.
