Data

These files contain data from test beam runs of detector components as well as data from the collider runs. Recall the general layout of our detector:

  • Central Tracker: a small region of silicon vertex detectors immersed in a magnetic field of 4 Tesla; the data indicate the reconstructed tracks of charged particles.
  • Electromagnetic Calorimeter: twenty layers of active gas chambers separated by layers of lead; the data indicate the amount of energy deposition in each layer.
  • Hadronic Calorimeter: twenty layers of active gas chambers separated by layers of uranium; the data indicate the amount of energy deposition in each layer.
  • Muon Catcher: plastic scintillators that indicate the passage of a muon; the data indicate muon detection with the word "Hit."
Look at these pictures that will help you visualize the layout:

Use the test-beam data to ensure system calibration and your own understanding of the detector data in the presence of known particles at a known energy. You can then apply this understanding to the data from the collider run.
