Reduce raw data rate of 40 MHz down to 750 kHz in 12.5 sec latency, preserving efficiency for mission-critical physics at the margin (precision Higgs, low-lying SUSY scenarios, vector boson scattering) Achieved by execution of custom particle reconstruction algorithms and selection decisions similar to offline physics analysis, optimized for speed and data transmission feasibility. Computed by a network of large, fast FPGAs mounted on custom PCBs in rows of crates in USC connected by high-speed backplanes and optical fibers. Exploiting the data from new subdetectors and electronics upgrades from existing ones. Combining the tracking data from the Track Trigger and the rest of the detector to provide the best achievable resolution for particle energy/momentum and remove the effects of pileup. 5 L1 Trigger Requirements Director's Progress Review -- Trigger OverviewJ.

L1 Trigger Requirements Calorimeter Trigger Process individual readout granularity cells from EB/HB/HF and optimized readout from HGC. Data processed by regional Layer and then final global reconstruction Layer providing the output. Similar to current calorimeter trigger, essentially scaled to higher number of channels involved. Endcap Muon Trigger Covering | | from 1.6 to 2.5: rebuilt to incorporate additional chambers in endcap and to provide input to the tracking correlator. Overlap & Barrel Muon Triggers Modifications of existing muon triggers covering the barrel and overlap regions to provide the input to tracking correlator. Global Correlator Trigger L1 Track Finding is contained within the Tracker, with L1 Trigger performing correlation of produced track with muon and calorimeter trigger information. Logic is based on adaptation of Particle Flow ideas to L1 Trigger. Input trigger data is processed by an input Layer 1 and then final Layer 2 providing output. Global Trigger Will need to process more information than Phase 1 from many more objects with additional Tracking Trigger load. Design scales by ratio of data volume from phase 1 upgrade.

C&S understood since based on Phase 1 Trigger Upgrade Systems experience Boards are extrapolations of existing Phase 1 Trigger Upgrade Boards Using most conservative costing model (construct with Phase 1 hardware) R&D and technology advances offer opportunities to reduce cost.

Senior Engineer becomes unavailable (Low Risk) Hire new engineer, subcontract to consulting firm, use FNAL engineer Software or Firmware does not meet requirements (Low Risk) Hire extra expert effort to recover schedule and help personnel Boards are delayed (design, manufacture or testing) (Low Risk) Hire extra effort to speed up testing schedule Vendor non-performance (Low Risk) Acquire spending authority to use alternative vendors (while original funds are being unencumbered). Input or output electronics (non-trigger) delayed (Low Risk) Built in capabilities of trigger electronics provide signals for their own inputs & outputs 25 Managed Trigger Risks & Mitigation Director's Progress Review -- Trigger OverviewJ.

Summary The L1 trigger project is essential to realize the physics goals of CMS during HL-LHC (precision Higgs, VBS, BSM), as well as realizing the full potential of other upgrades. US institutions plan to continue as the leading participants in L1 trigger R&D and production, with a proposal to build 50% of the final system and provide commensurate hardware and firmware engineering. A model of the US involvement has been developed with cost estimates in line with the CMS technical proposal, with appropriate level of detail entering the R&D phase of the project. Estimated total construction (R&D) cost of 8.5M$ (2.6M$) Director's Progress Review -- Trigger OverviewJ. Berryhill, 2016 February 2 27
