    • Fiducial cross-sections for [Formula: see text] production with one or two additional b-jets are reported, using an integrated luminosity of 20.3 fb[Formula: see text] of proton-proton collisions at a centre-of-mass energy of 8 TeV at the Large Hadron Collider, collected with the ATLAS detector. The cross-section times branching ratio for [Formula: see text] events with at least one additional b-jet is measured to be 950 [Formula: see text] 70 (stat.) [Formula: see text] (syst.) fb in the lepton-plus-jets channel and 50 [Formula: see text] 10 (stat.) [Formula: see text] (syst.) fb in the [Formula: see text] channel. The cross-section times branching ratio for events with at least two additional b-jets is measured to be 19.3 [Formula: see text] 3.5 (stat.) [Formula: see text] 5.7 (syst.) fb in the dilepton channel ([Formula: see text], [Formula: see text], and ee) using a method based on tight selection criteria, and 13.5 [Formula: see text] 3.3 (stat.) [Formula: see text] 3.6 (syst.) fb using a looser selection that allows the background normalisation to be extracted from data. The latter method also measures a value of 1.30 [Formula: see text] 0.33 (stat.) [Formula: see text] 0.28 (syst.)% for the ratio of [Formula: see text] production with two additional b-jets to [Formula: see text] production with any two additional jets. All measurements are in good agreement with recent theory predictions.

  • The ABC130 barrel module prototyping programme for the ATLAS strip tracker
  • 2020
  • Ingår i: Journal of Instrumentation. - : IOP PUBLISHING LTD. - 1748-0221. ; 15:9
  • Tidskriftsartikel (refereegranskat)abstract
    • For the Phase-II Upgrade of the ATLAS Detector [1], its Inner Detector, consisting of silicon pixel, silicon strip and transition radiation sub-detectors, will be replaced with an all new 100% silicon tracker, composed of a pixel tracker at inner radii and a strip tracker at outer radii. The future ATLAS strip tracker will include 11,000 silicon sensor modules in the central region (barrel) and 7,000 modules in the forward region (end-caps), which are foreseen to be constructed over a period of 3.5 years. The construction of each module consists of a series of assembly and quality control steps, which were engineered to be identical for all production sites. In order to develop the tooling and procedures for assembly and testing of these modules, two series of major prototyping programs were conducted: an early program using readout chips designed using a 250 nm fabrication process (ABCN-250) [2, 3] and a subsequent program using a follow-up chip set made using 130 nm processing (ABC130 and HCC130 chips). This second generation of readout chips was used for an extensive prototyping program that produced around 100 barrel-type modules and contributed significantly to the development of the final module layout. This paper gives an overview of the components used in ABC130 barrel modules, their assembly procedure and findings resulting from their tests.

  • IEC-61499 Distributed Automation for the Next Generation of Manufacturing Systems
  • 2019
  • Ingår i: The Digital Shopfloor: Industrial Automation in the Industry 4.0 Era Performance Analysis and Applications. - : River Publishers. ; , s. 103-127
  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • Global competition in the manufacturing sector is becoming fiercer and fiercer, with fast evolving requirements that must now take much more into account: rising product variety; product individualization; volatile markets; increasing relevance of value networks; shortening product life cycles. To fulfil these increasingly complex requirements, companies have to invest on new technological solutions and to focus the efforts on the conception of new automation platforms that could grant to the shopfloor systems the flexibility and re-configurability required to optimize their manufacturing processes, whether they are continuous, discrete or a combination of both. Daedalus is conceived to enable the full exploitation of the CPS’ virtualized intelligence concept, through the adoption of a completely distributed automation platform based on IEC-61499 standard, fostering the creation of a digital ecosystem that could go beyond the current limits of manufacturing control systems and propose an ever-growing market of innovative solutions for the design, engineering, production and maintenance of plants’ automation.
