Work with TRT in data taking mode
Goal
Introduction to modern methods of conducting high-energy physics experiments, detector parameters control and monitoring its characteristics in data taking mode by the example of TRT.
Students will be introduced to Data Acquisition System (DAQ) operation principles, detector systems slow control methods (DCS) and data monitoring concepts in both offline and online operation modes. Students access TRT state control system in demo mode via web interface. They process "raw" TRT data from proton-proton collisions and data saved as ROOT histograms using monitoring software (TRTViewer) available on MEPhI computers.
Overview
- Introduction to DAQ system, readout electronics and online event reconstruction
- Detector Control System: destination, operation principles, errors/failures propagation
- Significance of detector slow control parameters. Remote control
- Monitoring systems. Data representation in online mode
- TRTViewer: work with "raw" data and ROOT files obtained from various monitoring software
- TRT diagnostics. Significance of parameters under control
- Questions
More info
This work studies data acquisition and control systems by the example of TRT in ATLAS experiment at LHC.
Introductory lecture tells about TRT data acquisition and control systems. Students are introduced to main detector parameters control. Shifters' tasks during data-taking periods are also mentioned.
Students access TRT state control system in demo mode. They check accordance between observed and textbook parameters like voltage, temperature, gas flow etc.
Students process "raw" TRT data from proton-proton collisions and data saved as ROOT histograms using monitoring software (TRTViewer) available on MEPhI computers.
Finally, students answer test questions.
