  2. RadMon Document and Plots • First Results from the Online Radiation Dose Monitoring System, in ATLAS Experiment, ATL-COM-INDET-2011-123 • Description of monitoring system • Comparison of 2010 – 2011 measurements with FLUKA-based simulation • Measurement of doses and fluences with online radiation monitoring system in the Inner Detector, ATLAS-PLOT-INDET-2011-012

  3. FLUGG Plots from NSW TDR Ratio of measured to simulated MDT hit rate during a 7 TeV run at an average luminosity of 1.9 x 1033 cm-2 s-1 (50 ns bunch spacing) a) Measured hit rate in the region of the Small Wheel for L = 9.6 x 1032 cm-2 s-1 at √s=7 TeV in the CSC and MDT chambers as function of the radial distance from the beam line.

  4. Total Ionizing Dose Comparison of predicted and measured total ionizing dose (TID) in units of Gy in the Inner Detector as a function of time. Measurements with RadFETs are given by the solid lines for four sets of locations, and uncertainties given by the solid bands include measurement spread and systematic contributions. Predictions are from a FLUGG-based simulation.

  5. Non-Ionizing Energy Loss Comparison of predicted and measured non-ionizing energy loss (NIEL) expressed as 1-MeV neutron-equivalent fluence in the Inner Detector as a function of time. Measurements with diodes are given by the solid lines for four sets of locations, and uncertainties given by the solid bands include measurement spread and systematic contributions. Predictions are from a FLUGG-based simulation.

  6. Energy Deposition in 2012 Energy deposition in units of GeV/cm3/s as a function of z and r in the ATLAS detector predicted by the FLUGG-based background simulation program. The detector geometry is that for 2012 data-taking. The structure of the ATLAS detector, beam line shielding and the curved back wall of the cavern are clearly visible.

  7. Energy Deposition with IBL Beam Pipe Energy deposition in units of GeV/cm3/s as a function of z and r in the ATLAS detector predicted by the FLUGG-based background simulation program. The detector geometry is that for 2012 data-taking but with the new beam pipe to be used with the Pixel Insertable B-Layer. There is a reduction of 30% to 40% in energy deposition.
