The PolarquEEEst scientific programme consists in a series of measurements of the cosmic ray flux up to the highest latitudes. It started in Summer 2018, when three telescopes made out of scintillators readout by SiPMs were built and installed in Italy, Norway and on a sailboat leaving from North Island, to circumnavigate the Svalbard archipelago and land in Tromsø.

New high precision measurements of the cosmic charged particle rate beyond the Arctic Circle with the PolarquEEEst experiment
/ Abbrescia, M (INFN, Bari ; Bari U.) ; Avanzini, C (INFN, Pisa ; Pisa U.) ; Arlandoo, M (Oslo U.) ; Balbi, G (INFN, Bologna) ; Baldini, L (INFN, Pisa ; Enrico Fermi Ctr., Rome ; Pisa U.) ; Ferroli, R Baldini (Frascati ; Enrico Fermi Ctr., Rome) ; Batignani, G (INFN, Pisa ; Pisa U. ; Enrico Fermi Ctr., Rome) ; Battaglieri, M (INFN, Genoa ; Genoa U. ; Jefferson Lab) ; Boi, S (INFN, Cagliari ; Enrico Fermi Ctr., Rome ; Cagliari U.) ; Cavazza, D (INFN, Bologna) et al.
The goal of the PolarquEEEst experiment was to measure the cosmic charged particle rate at latitudes greater than 66$^{\circ }$ N, where no systematic and accurate measurements at sea level have ever been performed. A latitude range well above the Arctic Circle was explored on board of a sailboat, up to the unprecedented northernmost value of $82^{\circ }07^{\prime }$ N. [...]

From the Phase-0 DAQ upgrade of entire ATLAS Pixel Detector towards the Phase-2 electronics upgrade
/ Gabrielli, A (INFN, Bologna ; IASF, Bologna) ; Alfonsi, F (INFN, Bologna ; IASF, Bologna) ; Balbi, G (IASF, Bologna) ; D'Amen, G (INFN, Bologna ; IASF, Bologna) ; Gebbia, G (INFN, Bologna ; IASF, Bologna) ; Giangiacomi, N (INFN, Bologna ; IASF, Bologna)
The ATLAS Experiment has upgraded some off-detector readout chains during the 2013–2015 LHC shut down and an additional barrel layer has been inserted as part of the Pixel Detector: the Insertable B-Layer (IBL). The Layers 2 and 1 of the ATLAS Pixel Detector have also been upgraded, using the same Back Of Crate (BOC) and ReadOut-Driver (ROD) cards designed for IBL, while maintaining the front-end sensors unchanged. [...]

Measurements of Single Event Upset in ATLAS IBL
/ Balbi, G. (INFN, Bologna) ; Barbero, M. (Bonn U. ; Marseille, CPPM) ; Beccherle, R. (INFN, Genoa ; INFN, Pisa) ; Bindi, M. (Gottingen U., II. Phys. Inst.) ; Breugnon, P.

Effects of Single Event Upsets (SEU) and Single Event Transients (SET) are studied in the FE-I4B chip of the innermost layer of the ATLAS pixel system. SEU/SET affect the FE-I4B Global Registers as well as the settings for the individual pixels, causing, among other things, occupancy losses, drops in the low voltage currents, noisy pixels, and silent pixels.

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.
