Kick-Off: TDAQ Phase-II Upgrade - Overview Outline o High-level design o Effort and cost estimates o Organisation o Interim-Upgrade Project Leader o Next steps
Kick-Off: TDAQ Phase-II Upgrade - Overview • High-level design summary • Trigger o Efficiently select single electrons and muons with low thresholds (pT> 20 GeV) o Efficiently select di-photons, di-leptons and hadronic di - taus o For hadronic final states from jets use single jet, multi-jet, HT and ET miss o Hardware triggers are based on calorimeter and muon information, tracking information may be exploited in a hardware trigger • Data Acquisition o Homogenous detector readout (FELIX)—early transition from custom hardware to commodity computing and networking hardware and software o Receives detector data at up to 1 MHz and stores the data during the Event Filter decision time o The Event Filter includes hardware tracking processors to allow for regional tracking (if not already done at Level 1) and full event tracking (FTK++) o Up to 10 kHz of selected events transferred to mass storage • Software o Where appropriate Open software technologies o Application specific software
Kick-Off: TDAQ Phase-II Upgrade - Overview • High-level design summary ... cont. • Two-level hardware trigger—so called Level-0 – Level-1 scenario
Kick-Off: TDAQ Phase-II Upgrade - Overview • High-level design summary ... cont. • Two-level hardware trigger—so called Level-0 only scenario
Kick-Off: TDAQ Phase-II Upgrade - Overview
Kick-Off: TDAQ Phase-II Upgrade - Overview • High-level design summary ... cont. • Low latency Level-0 – Level-1 o Level-0 – Level-1 scenario with different latencies & rates (Cf. IDR) o Characterised by: • Level-0 rate up to 4 MHz • Level-0 latency 25 µ s (MPV – Maximum Possible Value) • Use of MDT moved to Level-1 • NSW reacts only to Level-1 • Scenarios being assessed by a sub-committee of the ATLAS Upgrade Steering Committee o Preliminary report (read presentation) by sub-committee presented to ATLAS Upgrade Steering Committee
Kick-Off: TDAQ Phase-II Upgrade - Overview • Initial estimate of required effort for CORE deliverables For the architecture with a Level-0 – Level-1 hardware trigger • Typically for the period 2018 – 2025 • Item 1.8 FTK++ includes effort common with item 1.7 Level-1 Track Trigger o Common with EFTrack in the Level-0 only scenario • Items 1.9.x include software effort
Kick-Off: TDAQ Phase-II Upgrade - Overview • Initial estimate of required CORE cost For the architecture with a Level-0 – Level-1 hardware trigger • Cost differences, savings and/or increases, in the two architectures described work in opposite directions at the level of the uncertainties of the costing performed for the scoping document o Cost difference for the low-latency Level-0 – Level-1 scenario being evaluated • Costing revision expected by end 2016 • To be compared to “possible available funds” o Information being compiled by ATLAS resource coordinator

Kick-Off: TDAQ Phase-II Upgrade - Overview • Evolution of TDAQ organisation … cont. • Phase-2 upgrade project leader o Coordinates all Phase-2 upgrade activities o Reports to ATLAS upgrade coordinator and Trigger and DAQ management team o Coordinates with Phase-1 Level-1 coordinator • Phase-1 Level-1 becomes the Phase-2 Level-0 • Specific Phase-2 system coordinators o Track triggering coordinator • Scope: L1Track or EFtrack and FTK++ hardware o Event selection coordinator • Scope: Target menu development; selection algorithms; simulation • Scope of some system coordinators increased to Phase-2 activities o Central trigger scope increased to cover L0CTP, L1CTP, RoIE & LTI o DAQ/Event Filter coordinator • Detector readout scope: FELIX and Data Handler • Dataflow scope: Storage Handler, event building, event aggregator and Event Filter o Where Event Filter refers to commodity hardware & infrastructure
Kick-Off: TDAQ Phase-II Upgrade - Overview • Evolution of TDAQ organisation … cont. • Phase-2 Working groups are established • Immediate objectives • Build on the sections of IDR titled “Areas of study up to the TDR” • Identify a list of distinct tasks to be completed up to the TDAQ Phase-2 TDR, including effort and timeline • Identify a set of milestones that will provide, on a quarterly basis, a measure of progress with respect to planning • Identify the non-core resources, e.g. testbeds, required for the work • Stimulate discussion • Encourage active participation • Initial work plans up to TDR by end of September TDAQ week
Kick-Off: TDAQ Phase-II Upgrade - Overview • Some next steps • December 2017: TDAQ Phase-2 upgrade TDR o End September 2017: final draft for ATLAS review (and LHCC Referees) o Target approval in first half 2018—not critical o To achieve this • Appoint Interim Phase-2 Upgrade Project Leader • End October: overall TDR editor and chapter editors • End November: detailed TDR outline; process and milestones to final draft • TDAQ Phase-2 Memorandum of Understanding (MoU) o To be presented to ATLAS at the same time as the TDR • November TDAQ general meeting • Presentation and discussion of work plan and schedule to TDR
Kick-Off: TDAQ Phase-II Upgrade - Overview • Interim Upgrade Project Leader • The Upgrade Organisation document prescribes the appointment of an interim upgrade project leader, with a term up to the approval of the TDR • Following consultations o Members of the TDSG; a sample of TDAQ members; TDAQ IB chair; o the ATLAS Upgrade Coordinator; the ATLAS spokesperson • The TDMT propose to appoint Francesco Lanni (BNL) as the TDAQ Phase-II Interim Upgrade project leader • Institutes represented in this meeting are requested to send any comments concerning this proposal to the TDMT and/or the TDIB chair by Friday 7 October. If no significant objections are raised by this date, the appointment will be considered to be endorsed
