2009 Start of LHC
Run 1: 7 and 8 TeV centre of mass energy, luminosity ramping up to
few 1033 cm-2 s-1, few fb-1 delivered
LHC shut-down to prepare machine for design energy
2013/14 and nominal luminosity
Run 2: Ramp up luminosity to nominal (1-2 x1034 cm-2 s-1), ~50 to 100 fb-1
2018 Injector and LHC Phase-I upgrades to go to ultimate luminosity
Assume up to
Run 3: Ramp up luminosity to 2.2 x nominal, reaching ~100 fb-1 / year 5×1034cm-2s-1 and
accumulate few hundred fb-1 25ns, so plan for
~ 80
~2022 Phase-II: High-luminosity LHC. New focussing magnets for very high
luminosity with levelling
Run 4: Collect data until > 3000 fb-1 Assume up to 1035cm-2s-1 and 25ns,
so plan for ~ 140
2030
Scopo upgrades
CMS ha dimostrato con i suoi risultaP di fisica le o'me prestazioni del suo
rivelatore
Le a'vita’ per consolidare e manutenere l’apparato per operare ad alta energia e
con luminosita’ fino a 2‐3 1034 cm‐2 s‐1 sono in corso
Sono in fase di completamento i TDR corrispondenP a nuove parP di apparato
da completare prima del 2022 (fase 1) e installare entro LS2
Vista la priorita’ assegnata al HL‐LHC dallo European Strategy Goup si sta
procedendo alla definizione degli upgrades che permeaeranno a CMS di operare
a luminosita’ > 5 1034 cm‐2 s‐1 con ~150 (fase 2)
La sfida nel 2013(‐14) e’ quella di completare le analisi dei daP 2012
concentrandosi sulle a'vita’ del LS1, mentre il disegno di fase 2 richiede
un’intensa campagna di simulazione per rivelatore e trigger
Europe’s top priority should be the exploita3on of the full poten3al of the LHC, including the
high‐luminosity upgrade of the machine and detectors with a view to collec3ng ten 3mes
more data than in the ini3al design, by around 2030

Collider Physics at Seoul (Korea)RPC system stability 2011‐2012
• The main milestone of the RPC project for the 2011‐2012 was: Stabilize the
performance of the RPC detector Muon reco and trigger
– Measure and monitor in `me the performance
– Calibrate the RPC system
• This required a big effort to the RPC community in term of thinking, experience and
manpower.
• Many improvements have been introduced since the 2011 to stabilize the detector
performance and they are:
1. 2011 HV scan (April 2011) HVapp = HVeff (1-α+αP/P0)
2. a “slow” (once per fill) WP automaPc correcPon, with α = 1 (July 2011)
3. 2012 HV scan (March 2012)
4. a “fast” WP automaPc correcPon (anyPme it changes of 3 V) (July 2012)
5. α value equal to 0.8, esPmated with the first data of the 2012 (November 2012)
• Thanks to the first two steps the chamber efficiency instability went down from
10% to 4‐5% and, finally, with α equal to 0.8, the amplitude of the oscilla`ons due
to atmospheric pressure varia`ons has been reduced by a factor 10 for the cluster
size and by a factor 4 for the efficiency (1%).

INSTALLATION milestones:
• Plus Endcap@October 2013. Needed 72 chambers or 36 SM
• Minus Endcap @February 2014. Needed 144 chambers or 72 SM 26RE4 upgrade
QC4 lab for supermodule assembly and test at
CERN. Some technical help welcome.
• The present schedule is “just in time” to achieve the installation milestones, but
we see no showstoppers for the time being.
• In case of unforeseen problems we could install Endcap minus in February
2014 and Endcap plus in August 2014. This is possible because supermodules
for minus and plus are identical.

DT: Sector Collector reloca`on
Phase 1 LS1 (2013-2014) pave way to the future:
Increase longevity and flexibility
- Replacement of theta TRB
- Relocation of Sector Collector from cavern to counting room
2013-2014
The Sector Collector reloca`on foresees to move the Level 2 Electronics of the DT (Sector
Collector) from the cavern (UXC) to the counPng room (USC).
In the tower racks subsPtuPng the present SC electronics there will be the CuOF System.
The system will make a 1 to 1 Copper to OpPcal Fibre conversion for the ReadOut Links
and Trigger Links.DT: stato aVvita' finanziate per LS1
Piano a'vita’ del 2009:
– sosPtuzione delle theta Trigger Board (TTRB) nei minicrates delle
camere MB1 delle ruote ±2 mira a ricosPtuire lo stock di boards spare
da uPlizzare come Phi TRB recuperando i moduli BTI dalle boards
sosPtuite. Le nuove boards usano FPGA che per le loro dimensioni
sono uPlizzabili solo per le theta boards.
– ProtoPpaggio e tests sono finiP. La produzione sta cominciando.
– Col trasferimento del Sector Collector da UXC a USC, i daP dei TDC e le
primiPve del trigger di tuae le 250 camere DT saranno disponibili in
USC su fibre o'che. Questo lavoro e` alla base di ogni futuro upgrade
del sistema DT. Il progeao e` stato esaminato (ECR) a Giugno 2012 da
Electronics e Technical CoordinaPon teams e approvato. Da allora si
sono fa' tests deaagliaP di trasmissione sui protoPpi dei nuovi link
o'ci culminaP con due tests a Dicembre e Febbraio in cui fino a 72
links sono staP installaP per prendere daP di cosmici e test pulses a
alto rate per diversi giorni. Lo stato del progeao e` stato esaminato in
una ESR a February, che ha dato l’OK per l’inizio della produzione di
massa dell’elearonica e per l’installazione delle fibre.DT Upgrade Phase 1 and Phase 2 PHASE 1 (not strictly related to LHC shutdown) (2015-2017) Exploit optical fibers bringing all chambers data in USC for running also a concurrent system for track finding. • Replacement of DTTF • Redesign of TSC and ROS boards • Optimize DT optical links for the new trigger upgrade electronics PHASE 2 (LS3) (2018 and beyond) • Insert connection with the tracker in the L1 trigger system • Partial replacement of Minicrate electronics which do not survive HL-LHC

• Xilinx Virtex 7 con 80 input veloci a 10GB/s
• Flessibilità a ridondanza (possibile aggiungere nuovi inputs, e.g. GEMs)R&D per FASE 2
46Trigger Performance and Strategy
• Key goal: maintain the physics acceptances of leptonic, photonic, and
hadronic trigger objects similar to 2012 (especially for low‐mass processes
like Higgs)
• Two key components under consideraPon for Phase 2:
1. L1 tracking trigger
2. a significant increase of L1 rate, L1 latency and HLT output rate
• Tracking at L1 will help maintain rates for muons, electrons & possibly taus.
Only limited improvement expected for photons & hadronic objects
• For these, it may be important to increase L1 rate substanPally. An increase
in rate requires significant changes to frontend electronics, so also consider
3. Increasing L1 latency from present 4 µs (Tracker) or 6.4 µs (ECAL) limit
Allows more Pme for more sophisPcated algorithms in new FPGAs and
architecture
“Target parameters” to focus the discussion
– 1 MHz rate and 20 µs latency
• CDAQ/HLT iniPal look: trends for networking/switching and mulP‐core
compuPng circa 2023
- “1 MHz input looks feasible” output rate would be up to 10 kHz48
Basic Parameter Scenarios
• Surveyed subsystems, DAQ, CompuPng led to consideraPon
of following basic parameter scenarios (so far):
– Actual: L1 rate = 100 kHz, L1 Latency = 6.4 μs (present = 4 μs)
• Used up to now to guide Phase 2 Tracker
– Scenario 2 (“non‐invasive”): L1 rate = 150 kHz, L1 Latency = 6.4 μs
• Survey among sub‐systems, (e.g. ECAL), suggests that L1 trigger rate can go
up to 150 kHz without change of front‐end electronics (to be further
confirmed).
– Scenario 3: L1 rate = up to 1MHz, L1 Latency: up to 20 μs
• Survey suggests feasible IF significant upgrades are carried out
• To set the scale: Task Force on EB FEE replacement ~10M CHF and 26
months of shutdown
• Clearly any such change requires good physics jus`fica`on,
and es`mates of work/cost for each subsystem
• Aim for final decision on this by early 2014
• In the interim, propose that ongoing work for Phase 2 be
compaPble with all scenarios
• Implies design changes for upgrade electronics (e.g. Tracker)Phase 2 Tracker
• Progress in system design and prototyping
– Prototype readout chips (CBC2) received from foundry
• With bump bonding to hybrid ‐ reads out two sensors with correlaPon logic
– Hybrid prototypes for CBC2 chips fabricated (2‐chip hybrids)
• in "rigid" technology ‐ design of "flex" proto proceeding in parallel
– Good progress on DAQ proto
• uTCA DAQ chain, fully integrated in XDAQ framework
• If components are good, expect to have a full prototype chain in summer
– CBC2, 2xCBC2 hybrid, Concentrator‐FPGA, GBT‐FPGA, GLIB‐FED/FEC
• Preparing a first TK‐Phase2 CMSSW so‚ware release
– All "phase‐2" so‚ware packages properly included in CMSSW
– Bug fixes in TK geometry and inacPve materials
– Improvements in low‐level reconstrucPon and new DetID scheme will come later
• Series of R&D reviews being planned (scope: Outer Tracker)
– Sensors: Feb 22
– Module design and FE electronics: Mar 18/19
– At least 3 more to be scheduled later on
– Open meePngs, everybody in CMS is welcome
49DT toward Phase 2
CMS is discussing the possibility of operating in Phase 2 with:
-1 MHz L1A rate (instead of 100 kHz)
-20 µs latency (instead of 6 µs as previously assumed. Now 3.2 us)
We are asked to provide statements about the implications in our subsystem.
Part of DT front end electronics is not designed for the PHASE 2 luminosity.
Time scale to develop new Minicrates ~7 years so it is necessary to start ~2015.
Studies are needed to make sure there are no bottlenecks.

– Plausible assumpPon is that detector opPmized for this also very
well suited to broader HL‐LHC physics program => to be verified
– Note: HI Physics consideraPons also included
• The Goal is Maintain and/or Improve signal acceptance &

– Endcap e, µ, τ, γ, b & top Jet tagging
– FWD Jet tagging for VBF & WW scaaering

• physics performance will likely not be maintained in the higher η
acceptance range 53Detector Upgrades
• Muons
– robust trigger to match scope of track trigger, out to η ~ 2.2
– improve Muon momentum measurement out to η = 2.4
if the B‐field permits*
– extend Muon tagging beyond η = 2.4 ?
*Bucking coil to improve B‐field in forward region?
• OpPons for Possible Calorimeter Replacements
– EE: Evaluate Shashlik opPons + others
– HE: Keep exisPng absorber, replace scint plates ‐ higher granularity, at least
high η Other opPons include replacing exisPng absorber; Čerenkov/
IonizaPon readout
– HF: Replace with similar (replace fibers?), or more compact detector inside
plug
• PU miPgaPon: consider two approaches
– Extend tracking to η~4 with system of pixel disks, integrate with Phase 2
tracker
– Add precision Pming: consider EM pre‐shower a possible straw man calo‐TOF

– EsPmate the resoluPon needed in endcap/forward calorimeters
– EsPmate benefit from extended η acceptance of current sub‐systems
– Demonstrate need/feasibility of pile‐up miPgaPon (forward tracking ‐ precision Pming)
• Need a campaign of simulaPon studies in 2013
lead into decisions on Phase 2 scope/opPons by early 2014
– Establish physics driven detector requirements
– Present conceptual ideas and physics reach at ECFA workshop and Oct. Upgrade week
– Guide and prepare further studies and development of baseline detector concepts
– Demonstrate the physics reach with straw man detector concepts

• Defining Scope of Phase 2 Upgrade
– Describe program of work to converge on scope: upgrade opPons, simulaPon studies,
considering physics performance and cost
– As for Phase 1, following the TP for the whole program, will prepare TDRs for the
individual projects
• Upgrades under ConsideraPon ‐ See next slide
• R&D

Infrastructure for Trigger Upgrade
• We will face of 50 or more interacPons before LS2.
– Above about 30, the L1‐Trigger rate will be a serious issue, and an
upgrade to the trigger is planned.
– We expect to present a TDR to the LHCC in early 2013.
• Upgrading trigger in an operaPng experiment is not easy
– A new system requires significant commissioning Pme
– LS1 work plan includes installaPon of parallel trigger inputs
• Allows commissioning of a new trigger alongside the operaPng trigger.
• Eliminates the requirement that the trigger upgrade occurs only during
LS2, and allows the plan to be driven by the LHC performance.
– Ensures robust running and minimal risk of data loss.
• Requires ~0.5MCHF of funding early in 2013
– To implement the changes during LS1
85Upgrade Common Items
• Financing of Common Items
– Direct contribuPons from FAs to specific Common Items in the
Upgrades Cost‐Sharing‐Matrix or from the Upgrades Common
Fund (CF).
• Upgrades Common Fund (CF)
