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

Project
Fermilab Director's Review -- US CMS Trigger Upgrade 25
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 triggerWesley Smith, 16 July 2013

Project
Fermilab Director's Review -- US CMS Trigger Upgrade 33
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 onwardsWesley Smith, 16 July 2013
Overall Trigger Risks
LHC CMSDetectorUpgrade
Project
Fermilab Director's Review -- US CMS Trigger Upgrade 34
Safety: follows procedures in CMS-doc-11587, FESHM L2 Manager (W.S.) responsible for applying ISM to trigger upgrade.
o 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.

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 2015Wesley Smith, 16 July 2013
Cost & Schedule Understanding

Fermilab Director's Review -- US CMS Trigger Upgrade 36
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

Response to Recommendationsfrom May Review
LHC CMSDetectorUpgrade
Project
Fermilab Director's Review -- US CMS Trigger Upgrade 37
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.Wesley Smith, 16 July 2013
