Irradiation Studies related to the Bias Behaviour of the MightyPix — Johannes Albrecht1, •Jonas Rönsch1, Sebastian Rüssmann1, Klaas Padeken2, Hannah Schmitz2, Niclas Sommerfeld2, Dirk Wiedner1, and Lukas Witola1 — 1TU Dortmund University, Dortmund, Germany — 2Helmholtz Institute for Radiation and Nuclear Physics, Bonn, Germany
To exploit the full flavour physics potential of the HL-LHC, the LHCb detector will be operated at an unprecedented instantaneous luminosity after long shutdown 4. Due to the new conditions, an upgrade of the tracking system is unavoidable. The Mighty Tracker will be the downstream LHCb Upgrade 2 tracking system. It combines scintillating fibres and high voltage monolithic active pixel sensors (HVMAPS) called MightyPix.
The MightyPix will be placed in the inner part of the detector. Therefore, they encounter irradiation levels up to 3×10141-MeVneqcm−2.
As part of the radiation tolerance studies, several MightyPix were irradiated at the Isochronous Cyclotron of the Helmholtz Institute for Radiation and Nuclear Physics in Bonn up to a fluence of 3×10151-MeVneqcm−2. The effect of the irradiation on the complex system of the monolithic sensor will be presented.
