  3. Outline • Trigger TDR Status, Overall Goals • Overview of Trigger Upgrade Design • Muon Trigger Upgrade • Calorimeter Trigger Upgrade • Overview of Cost & Schedule Fermilab Director's Review -- US CMS Trigger Upgrade

  4. L1 Upgrade TDR • Final presentation to LHCC was Tuesday June 11th • Public version of the TDR here:https://cds.cern.ch/record/1556311 • Given approval, although still awaiting final formal LHCC write-up Fermilab Director's Review -- US CMS Trigger Upgrade

  5. L1 Trigger Upgrade – overview • Trigger rates are driven by the increase in luminosity, the center-of-mass energy, & by higher Pile-Up • Detector readout systems limit Level-1 trigger output rate to 100 kHz, latency to 4 μsec. LHC beams collide every 25 ns. • Mitigate by improving e/γ isolation, τ id, μ pT resolution, μ isolation, jets with PU subtraction & L1 menu sophistication • Increase system flexibility with high bandwidth optical links and large FPGAs, and standardize on μTCA telecom standard • Build and commission upgrade in parallel with current trigger system to safeguard physics, decouple from LHC schedule • Overall design: • Two-layer calorimeter trigger with tower-level precision and PU subtraction • Integrated muon trigger combining all CSC, DT & RPC systems in track-finding Fermilab Director's Review -- US CMS Trigger Upgrade

  22. Calorimeter Trigger Risk Mitigation • Goal (Original): • Provide readout of original RCT descoped during construction project • Present readout through GCT input buffer not workable with trigger evolution • Uses connection to a single CTP6 prototype or CTP7 card for DAQ readout • optical Receiver Summary Card (oRSC) paid by DOE Nuclear • VME Slave Interface Card • Fits in current RCT Crates (1 per crate) • 18 Cards in 2015 System • Receives RCT Jet Sum Card Outputto GCTon Copper “SCSI” Data Cables • Provides direct optical input to GCT • Bypassing old optical conversion cards • Planned use for Heavy Ion Triggers • Prototype under test  • Multiple optical outputs provide: • Inputs for upgrade calorimeter trigger &parallel operation of old & new trigger wherever ECAL & HCAL electronics notavailable in 2015 Fermilab Director's Review -- US CMS Trigger Upgrade

  24. Trigger Staging • CTP7 M&S: no HB/HE Backend until 2016 • Delay purchase of 34 CTP7 cards until FY15 • Use 12 CTP7 Cards w/prototypes as additional spares & for test setups. • Connected as shown on previous slide • EMU CSCTF M&S: one endcap in 2015 & other in 2016 • Commission & test one endcap thoroughly so 2nd can be integrated quickly • Delay spares & use prototypes for spares, test setups • Compatible with Global Muon Trigger using different Endcap inputs • Stages and Content: Fermilab Director's Review -- US CMS Trigger Upgrade

  25. Technical Feasibility • Working prototypes for all major cards exist & have passed tests • Production quotes exist for all critical parts with confirmed delivery upon order • Upgrade is based upon common μTCA hardware platform also used by HCAL & other CMS systems • Common hardware components across subsystems: Virtex-7 FPGA, multi-gigabit optical links • Many handles to facilitate testing – test-pattern injection, spy-buffer readout as well as test stands • Upgrade trigger project replaces existing trigger hardware built by the same team → interfaces well understood • Same team wrote software & firmware for existing trigger system → scope & requirements well understood • Requirements are frozen in approved Trigger TDR • System is commissioned & operated in parallel with existing trigger Fermilab Director's Review -- US CMS Trigger Upgrade

  33. Overall Trigger Risks • Senior Engineer becomes unavailable • Hire new engineer, subcontract to consulting firm, use FNAL engineer • Funding is delayed • Commission with prototypes and/or fewer production boards • Software or Firmware does not meet requirements • Hire extra expert effort to recover schedule and help personnel • Boards are delayed (design, manufacture or testing) • Hire extra effort to speed up testing schedule • Vendor non-performance • Acquire spending authority to use alternative vendors (while original funds are being unencumbered). • Input or output electronics (non-trigger) delayed • Built in capabilities of trigger electronics provide signals for their own inputs & outputs • Overall Risk Mitigation Strategy: • Continue to provide fully operational current trigger system in parallel with upgrade commissioning • Partial operation of the upgrade systems provide tangible benefits from 2015 onwards Fermilab Director's Review -- US CMS Trigger Upgrade

  34. Trigger ESH&Q • Safety: follows procedures in CMS-doc-11587, FESHM • L2 Manager (W.S.) responsible for applying ISM to trigger upgrade. • Under direction of US CMS Project Management • Fermilab employees and CMS collaborators working at Fermilab & CERN receive training in accordance with Fermilab & CERN policies. Personnel conducting work at collaborating institutions are trained in accordance with the policies of those institutions. • Regular US CMS Upgrade Mgm’t meetings review work activity, schedule, costs, hazards, risks and controls. • Quality Assurance: follows procedures in CMS-doc-11584 • Regularly evaluate achievement relative to performance requirements & appropriately validate or update performance requirements & expectations to ensure quality. • QA: Equipment inspections & verifications; Software code inspections, verifications, & validations; Design reviews; Baseline change reviews; Work planning; and Self-assessments. • Graded Approach: • Apply appropriate level of analysis, controls, and documentation commensurate with the potential to have an environmental, safety, health, radiological, or quality impact. • Four ESH&Q Risk levels are defined & documented in CMS-doc-11584. Fermilab Director's Review -- US CMS Trigger Upgrade

  35. Cost & Schedule Understanding • C&S understood since prototypes for all major cards have been built & have passed tests • C&S based on experience of the same team that built original CMS calorimeter & muon trigger systems • Hardware is based upon common μTCA hardware platform also used by HCAL & other CMS systems • Same team wrote software & firmware for existing trigger system → scope & requirements well understood • Requirements are frozen in approved Trigger TDR • Schedule is robust because it always provides a working trigger at each stage with parallel operation of old & new trigger systems, commissioning & testing of new system during data-taking (with data) & evolution to final system while providing immediate availability of improved trigger in 2015 Fermilab Director's Review -- US CMS Trigger Upgrade

  36. Response to Recommendationsfrom May Review • Develop a plan prior to the CD-1 review for procurement of components that need to be installed prior to the end of LS1. • These components are the Muon Port Card Mezzanines and MPC-EMUTF Optical Fibers that must be installed in the collision hall during LS1. • These components are being moved to the operations program so they can be purchased in 2013. • Incorporate the missing information identified within comment section into the CDR prior to the CD-1 review. • This has been done and the CDR has been revised Fermilab Director's Review -- US CMS Trigger Upgrade

  37. Conclusions • Trigger Upgrade is technically feasible since based on working prototypes, & built by the same team that built original CMS Calorimeter & Muon triggers. • Trigger Upgrade can be accomplished within Cost & Schedule since based on working prototypes and experience in building the original CMS Calorimeter & Muon triggers. • Risks are understood and familiar due to team experience – risk is mitigated by parallel operation of existing and upgraded calorimeter systems • Plan to complete prototyping and begin production when approved.
