RD53 Pixel Readout Integrated Circuits for ATLAS and CMS HL-LHC Upgrades / Christiansen, Jorgen (CERN) /RD53 Collaboration
The RD53 collaboration has since 2013 developed new hybrid pixel detector chips with 50x50um$^2$ pixels for the HL-LHC upgrades of the ATLAS and CMS experiments at CERN. A common architecture, design and verification framework has been developed to enable final pixel chips with different chip sizes to be designed, verified and tested to handle extreme hit rates of 3GHz/cm$^2$ (12GHz per chip) together with significantly increased trigger rate of 1MHz and efficient readout of up to 5.12Gbits/s per pixel chip.
