TID Irradiation of the ATLAS ITkPix readout chip — Patrick Ahlburg, Yannick Dieter, Fabian Hügging, Hans Krüger, •Konstantin Mauer, Maximilian Mucha, Marco Vogt, and Jochen Dingfelder — Physikalisches Institut, University of Bonn, Germany
The upcoming High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will significantly increase the instantaneous luminosity. This will lead to a higher track density, a higher hit rate and thus an increased amount of radiation damage in the experiments.
For this reason, the ATLAS experiment will be upgraded and a new all-silicon inner tracking (ITk) detector has been designed, consisting of strip and pixel modules. The pixel modules are used in the innermost layers of the detector and have a hybrid design where a sensor is read out with a dedicated readout chip called ITkPix. Both components are designed to be radiation hard. The readout chip itself has to withstand up to 700 Mrad TID damage in SiO2.
In this talk an X-ray irradiation campaign to verify the radiation hardness and characterize the performance of the production version of the ITkPix will be presented.
