Speaker: Hans Wenzel

  We will discuss the Online Monitoring and Module Maintenance for CDF in the upcoming Fermilab Tevatron Run II. The CDF experiment consists of many detector subsystems and will run in a high rate large bandwidth data transfer environment. In the experiment, it is crucial to monitor the performance of each subsystem and the integrity of the data in real time with no interruption. The results of the monitoring should be available online even from remote sites. We choose ROOT as the main analysis tool for the monitoring systems. ROOT is a comprehensive object oriented framework, currently under development at CERN, that provides a foundation to build data acquisition, simulation and data analysis systems in Particle Physics. The availability of shared memory classes, browser classes , histogramming classes, socket connection classes , GUI classes, etc. makes ROOT an attractive choice for online monitoring. We will present the current status of the CDF online monitoring project and discuss its performance and the experience we made with ROOT.
  The data acquisition module information needed for online monitoring is provided by a database application which keeps track of the exact location, repair history, modification history and status of all modules during development, commissioning and accelerator operations. This database uses ORACLE. Reporting is available through Oracle reports, Crystal Reports, a flexible perl cgi script (MISWEB) and sql scripts. Input is available through the Oracle web interface and a custom java interface, used by the CDF Silicon Project to provide real time input of data from the module and detector test stands during acceptance testing of the data acquisition modules. We will discuss the implementation and status of the database.
