/ Loddo, F (INFN, Bari) ; Andreazza, A (Milan U. ; INFN, Milan) ; Arteche, F (Sao Paulo, Inst. Tech. Aeronautics) ; Barbero, M B (Marseille, CPPM) ; Barillon, P (Marseille, CPPM) ; Beccherle, R (INFN, Pisa) ; Bilei, G M (INFN, Perugia ; Perugia U.) ; Bjalas, W (CERN) ; Bonaldo, S (INFN, Padua ; Padua U.) ; Bortoletto, D (Oxford U.) et al.
The Phase-2 upgrades at the High-Luminosity LHC of ATLAS and CMS experiments at CERN will require a new tracker with readout electronics operating in extremely harsh radiation environment (1 Grad), high hit rate (3.5 GHz/cm2) and high data rate readout (5 Gb/s). The RD53 collaboration is a joint effort between the ATLAS and CMS to qualify the chosen 65 nm CMOS technology in high radiation environment and develop the pixel readout chips of both experiments.

The CMS Phase-1 Pixel Detector Upgrade
/ CMS Tracker Group of the CMS Collaboration
The CMS detector at the CERN LHC features a silicon pixel detector as its innermost subdetector. The original CMS pixel detector has been replaced with an upgraded pixel system (CMS Phase-1 pixel detector) in the extended year-end technical stop of the LHC in 2016/2017. [...]

An Improved Algorithm for On-Chip Clustering and Lossless Data Compression of HL-LHC Pixel Hits
/ Baruffa, Giuseppe (Perugia U.) ; Placidi, Pisana (INFN, Perugia ; Perugia U.) ; Di Salvo, Andrea (INFN, Turin ; Polytech. Turin) ; Marconi, Sara (CERN) ; Paternò, Andrea (INFN, Turin ; Polytech. Turin)
A prototype chip, called RD53A, has been designed by the RD53 collaboration to face the very high hit and trigger rate requirements (up to 3 GHz/cm$^2$ and 1 MHz, respectively) of the High Luminosity LHC experiment upgrades. In this paper, an improved algorithm for data compression, capable of sustaining the very high data volume and proposed to be implemented in the periphery of the chip, is presented: it exploits Run Length Encoding (RLE) and Variable Length Coding (VLC) to compact chip pixel hit patterns.

Experimental Study of Different Silicon Sensor Options for the Upgrade of the CMS Outer Tracker
/ Tracker Group of the CMS Collaboration
During the high-luminosity phase of the LHC (HL-LHC), planned to start around 2027, the accelerator is expected to deliver an instantaneous peak luminosity of up to $7.5\times10^{34}$ cm$^{-2}$s$^{-1}$. A total integrated luminosity of $3000$ or even $4000$~fb$^{-1}$ is foreseen to be delivered to the general purpose detectors ATLAS and CMS over a decade, thereby increasing the discovery potential of the LHC experiments significantly.

Design implementation and test results of the RD53A, a 65 nm large scale chip for next generation pixel detectors at the HL-LHC
/ Marconi, S (Marseille, CPPM) ; Barbero, M B (Marseille, CPPM) ; Fougeron, D (Marseille, CPPM) ; Godiot, S (Marseille, CPPM) ; Menouni, M (Marseille, CPPM) ; Pangaud, P (Marseille, CPPM) ; Rozanov, A (Marseille, CPPM) ; Breugnon, P (Marseille, CPPM) ; Bomben, M (Paris U., VI-VII) ; Calderini, G (Paris U., VI-VII) et al.
The RD53A large scale pixel demonstrator chip has been developed in 65 nm CMOS technology by the RD53 collaboration, in order to face the unprecedented design requirements of the pixel 2 phase upgrades of the CMS and ATLAS experiments at CERN. This prototype chip is designed to demonstrate that a set of challenging specifications can be met, such as: high granularity (small pixels of 50×50 or 25× 100 µm2) and large pixel chip size (~2x2 cm2), high hit rate (3 GHz/cm2), high readout speed, very high radiation levels (500 Mrad - 1 Grad) and operation with serial powering.
