TPX Data Analysis

• Luminosity internal precision (vdM scan, activation, long-term stability, hits, neutrons, energy deposits)

• Luminosity comparison versus ATLAS reference (calibration transfer, long-term stability)

• Luminosity display in the ATLAS control room

• Radiation field simulation and measurement comparison

• Radiation hardness determination
