. Overlap & Barrel Muon TriggersModifications of existing muon triggers covering the barrel and overlap regions to provide the input to tracking correlator.

Track Trigger Correlator

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 TriggerWill 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.

Phase 2 Trigger R&D Goals

Challenges:

Large increase in trigger input datae.g. present EB 5x5 trigger towers vs. full xtal

granularity – a x25 increase.Large increase in processing complexityTracking informationFine grain calorimeter informationFitting Muon and Tracking data together

More complex objects, conditions and algorithms

Phases:

Establish algorithms, techniques and feasibility

Decide on a hardware framework

Build prototypes to test functionalityBuild individual parts of the systemConstruct demonstratorsConnect to detector prototypes to validate designs

Phase 2 Trigger Algorithm R&D

Goal:

Allow development of calorimeter, muon, tracking trigger electronics – specify:Planned AlgorithmsNecessary trigger primitives

Link counts and formatsPlan:Initial definition of trigger algorithms, primitive objects and inter-layer objects (TP.L1.1) –

2Q2016

aseline definition

trigger algorithms, primitive objects and interchange requirements with subdetectors. (TP.L1.3) – 2Q2017

Detailed Software emulator demonstrates implementation of core phase 2 trigger menu with baseline objects

Phase 2 Trigger Hardware R&D - II

Hardware R&D Milestones – II

Full-function prototypes produced which allow local comparison with emulator (TP.L1.6) – 4Q2018

First boards which have sufficient channels, processing capability and bandwidth optical links to meet the requirements of the final boardsThese boards will cover only a portion of the trigger processing logic, however, and only local comparisons will be possible between hardware behavior and the emulator.Demonstrator system shows integration and scaling, global/full-chain comparison with

emulator

(

TP.L1.7)

–

4Q2019End-to-end comparisons over a slice of the detector which include multiple full-capability prototype boards and the

prototype full

-capability infrastructure

Goal of demonstrating a prototype system with its infrastructure and testing

environment capable of being connected to its front end detector for test-beam validation to follow.

Final Milestone:Phase 2 Trigger TDR (TP.L1.8) – 1Q2020Based on results

from

Change in formatting

of L1 input data from detector groups (HGC)

Change in DAQ output bandwidth implies more severe L1 performance requirements to compensate.Computing capacity of

available FPGAs or transmission speed of links at production phase may constrain choice of architecture and algorithms Uncertain division of responsibility internationally (including L1 track trigger). Upon organizing, coordination of hardware and firmware production.

Summary

The L1 trigger project is

essential to realize most of the physics goals of CMS during HL-LHC (precision Higgs, VBS, all but the highest mass BSM), as well as realizing the full potential of other upgradesUS

institutions plan to continue as the leading participants in L1 trigger R&D and production, with a proposed CORE contribution ~50%.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.
