Kick-Off: TDAQ Phase-II Upgrade - Overview

• High-level design summary
• Trigger
• Efficiently select single electrons and muons with low thresholds (pT> 20 GeV)
• Efficiently select di-photons, di-leptons and hadronic di-taus
• For hadronic final states from jets use single jet, multi-jet, HT and ET miss
• Hardware triggers are based on calorimeter and muon information, tracking

information may be exploited in a hardware trigger

• Data Acquisition
• Homogenous detector readout (FELIX)—early transition from custom hardware to

commodity computing and networking hardware and software

• Receives detector data at up to 1 MHz and stores the data during the Event Filter

decision time

• The Event Filter includes hardware tracking processors to allow for regional tracking

(if not already done at Level 1) and full event tracking (FTK++)

• Up to 10 kHz of selected events transferred to mass storage
• Software
• Where appropriate Open software technologies
• Application specific software

• 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
• Level-0 – Level-1 scenario with different latencies & rates (Cf. IDR)
• Characterised by:
• Level-0 rate up to 4 MHz
• Level-0 latency 25 µs (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

• Preliminary report (read presentation) by sub-committee presented to ATLAS Upgrade

Steering Committee

• 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

• 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

• f the costing performed for the scoping document
• 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”
• Information being compiled by ATLAS resource coordinator

Shows only those aspects of organisation relative to Phase-II

• Evolution of TDAQ organisation … cont.
• Phase-2 upgrade project leader
• Coordinates all Phase-2 upgrade activities
• Reports to ATLAS upgrade coordinator and Trigger and DAQ management team
• Coordinates with Phase-1 Level-1 coordinator
• Phase-1 Level-1 becomes the Phase-2 Level-0
• Specific Phase-2 system coordinators
• Track triggering coordinator
• Scope: L1Track or EFtrack and FTK++ hardware
• Event selection coordinator
• Scope: Target menu development; selection algorithms; simulation
• Scope of some system coordinators increased to Phase-2 activities
• Central trigger scope increased to cover L0CTP, L1CTP, RoIE & LTI
• DAQ/Event Filter coordinator
• Detector readout scope: FELIX and Data Handler
• Dataflow scope: Storage Handler, event building, event aggregator and Event Filter
• Where Event Filter refers to commodity hardware & infrastructure

Kick-Off: TDAQ Phase-II Upgrade - Overview

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
• End September 2017: final draft for ATLAS review (and LHCC Referees)
• Target approval in first half 2018—not critical
• 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)
• 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
• Members of the TDSG; a sample of TDAQ members; TDAQ IB chair;
• 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
