After a long design and development, a prototype of the pixel detector front-end chip that will be proposed for the ATLAS and CMS experiments at CERN during HL-LHC has been recently available. It provides data streams using up to four lanes running at 1.28 Gbps each. This paper describes in detail the implementation of a first readout chain of this chip, namely the RD53A, using the current the...
The LHC is planning an upgrade program which will bring the luminosity up to about 7.5E34 cm$^{-2}$s in 2027, with the goal of an integrated luminosity of 3000 fb$^{-1}$ by the end of 2037. This High Luminosity scenario, HL-LHC, will present new challenges of higher data rates and unprecedented radiation levels for the pixel detector (2E16 n$_{eq}$cm$^{-2}$, or equivalently 1 Grad, is expected...
The Compact Muon Solenoid (CMS) silicon tracker will be replaced at the High Luminosity Large Hadron Collider (HL-LHC) upgrade by a new radiation-hard detector capable of handling higher pileup, higher data rates, and longer trigger latency. RD53A prototype chip in a 65 nm feature size CMOS technology has been developed by RD53 Collaboration to meet these requirements. Meeting the performance...
The ATLAS upgrade programme for the high-luminosity large hadron collider (HL-LHC) includes the replacement of the inner tracking detector with an all-silicon system. The outer layers of the new tracker consist of strip sensors and the inner region is made up of pixel sensors. This paper describes the development of the endcaps for the pixel system. The endcaps are built from half-rings...
The RD53 Collaboration has been tasked with the development of Pixel detector readout chips for the upgrades of the silicon detectors of the ATLAS and CMS experiment for the HL-LHC era. ?This talk will summarise the results achieved with the first large size demonstrator chip developed by the RD53 collaboration, named RD53A. RD53A contains 76,800 pixels with 50 by 50 $\mu m^2$ pitch. RD53A...
