Project description

  • Analyse RPC detector noise data to study ageing of RPC panels and FE electronics as a function of time and integrated luminosity
  • Identify and mask noisy RPC strips to improve operational performance and reduce trigger rates

ToDo items

  • Implement code to use +/- 100 ns window to compute noise to remove spikes at start/end of inclusive time window
  • Normalise 2d noise rate to Hz (same procedure as 1d rates)
  • Plot noise rates of individual strips and panels versus integrated luminosity and also run number
  • Measure noise rates using collision data using +/- 100 ns window but removing +/- 25 ns central window to veto collision muons
  • Publish on website a text file with strip/panel noise rates for each collision run

RPC noise runs

For USTC people, these datasets can be found here: /home/msessa/storage

 $ eos ls /eos/atlas/atlastier0/rucio/data17_comm/calibration_RPCNoise
