In the high luminosity scenario of the LHC (HL-LHC), which will bring the instantaneous luminosity up to 7.5 x 10^34 cm^−2 s^−1, ATLAS and CMS will need to operate at up to 200 interactions per 25 ns beam crossing time and with up to 4000 fb^-1 of integrated luminosity. To achieve their physics goals the experiments will need to improve the tracking resolution and the ability to selectively...

The ATLAS experiment is currently preparing for an upgrade of the Inner Tracking for High-Luminosity LHC operation, scheduled to start in 2027. The radiation damage at the maximum integrated luminosity of 4000/fb implies integrated hadron fluencies over 2x10^16 neq/cm2 and tracking in very dense environment call for a replacement of the existing Inner Detector. An all-silicon...
The ITkPixV1 readout chip was designed by the RD53 collaboration as the pre-production chip for the ATLAS Inner Tracker (ITk) Pixel detector upgrade and is the successor of the RD53A demonstrator chip. It features a 400x384 pixel array with each pixel being 50um by 50um size. The chip was designed in 65nm CMOS technology and is optimised for the operation as the innermost pixel layer in the...
