Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider at CERN
/ Balbi, Gabriele (Universita e INFN, Bologna)
/ATLAS Collaboration
The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector, that has undergone significant hardware and readout upgrades to meet the challenges imposed by the higher collision energy, pileup and luminosity that are being delivered by the Large Hadron Collider (LHC), with record breaking instantaneous luminosities of 2 x 1034 cm-2 s-1 recently surpassed. The key status and performance metrics of the ATLAS Pixel Detector are summarised, and the operational experience and requirements to ensure optimum data quality and data taking efficiency will be described, with special emphasis to radiation damage experience..

A Multi-Channel PCI Express Readout Board Proposal for the Pixel Upgrade at LHC
/ Gabrielli, Alessandro (U. Bologna, DIFA ; INFN, Bologna) ; Alfonsi, Fabrizio (INFN, Bologna ; U. Bologna, DIFA) ; D'Amen, Gabriele (INFN, Bologna ; U. Bologna, DIFA) ; Giangiacomi, Nico (INFN, Bologna ; U. Bologna, DIFA) ; Balbi, Gabriele (INFN, Bologna) ; Falchieri, Davide (INFN, Bologna) ; Pellegrini, Giuliano (INFN, Bologna) ; Travaglini, Riccardo (INFN, Bologna)
After having designed and commissioned the readout electronics currently implemented in the Insertable B-Layer, Layer 1 and Layer 2 of the ATLAS Pixel Detector (B-Layer and Disk readout electronics is under commissioning), we have designed a new readout electronic board looking primarily at the upgrade of the LHC Pixel Detectors. Two prototypes of a PCI Express board, namely Pixel_ROD, featuring all the minimal input-outputs interfaces to address the future front-end readout electronics, have already been fabricated and tested.

General purpose readout board $\pi$ LUP: overview and results
/ Giangiacomi, Nico (Bologna U. ; INFN, Bologna) ; Alfonsi, Fabrizio (Bologna U. ; INFN, Bologna) ; d'Amen, Gabriele (INFN, Bologna ; U. Bologna, DIFA) ; Balbi, Gabriele (INFN, Bologna) ; Falchieri, Davide (INFN, Bologna) ; Gabrielli, Alessandro (Bologna U. ; INFN, Bologna) ; Gebbia, Giuseppe (INFN, Bologna ; U. Bologna, DIFA) ; Pellegrini, Giuliano (INFN, Bologna) ; Soverini, Davide (Bologna U. ; INFN, Bologna) ; Travaglini, Riccardo (INFN, Bologna)
This work gives an overview of the PCI-Express board $\pi$LUP, focusing on the motivation that led to its development, the technological choices adopted and its performance. The $\pi$LUP card was designed by INFN and University of Bologna as a readout interface candidate to be used after the Phase-II upgrade of the Pixel Detector of the ATLAS and CMS experiments at LHC.

100Gbps PCI-express readout for the LHCb upgrade
/ Durante, Paolo (CERN) ; Neufeld, Niko (CERN) ; Schwemmer, Rainer (CERN) ; Marconi, Umberto (INFN, Italy) ; Balbi, Gabriele (INFN, Italy) ; Lax, Ignazio (INFN, Italy)
We present a new data acquisition system under development for the next upgrade of the LHCb experiment at CERN. We focus in particular on the design of a new generation of readout boards, the PCIe40, and on the viability of PCI-express as an interconnect technology for high speed readout. [...]
