Studies on Irradiated Silicon Sensors for the CMS Tracker at the HL-LHC = Studien an bestrahlten Siliziumsensoren für den CMS Spurdetektor am HL-LHC

For the high luminosity phase of the LHC at CERN, the strip tracker of the CMS Experiment will be replaced due to higher demands on track density, track trigger and radiation damage. To study these aspects, more than 40 different silicon sensors were irradiated. Besides lab measurements, tests in an electron beam and Lorentz angle measurements were performed. A simulation model, which is capable to predict the charge distribution after a particle hit has been developed from these measurements.
