In this talk I am describing US contribuJons to the MTD as a planning package. Hence the MTD porJon of the project will be at a different level

  • f maturity relaJve to the other

subprojects. The specificity of the contents of this plan (WBS, KPPs, BoEs) will increase as the project evolves.

402.8 Requirements: Science Drivers

Charge #1

§ HL-LHC: large increase in beam intensity – and consequent number of simultaneous pp collisions (pileup, PU)

§ Baseline: Peak L = 5.0E34 cm-2s-1 à 140 PU § UlJmate: Peak L = 7.5E34 cm-2s-1 à 200 PU

§ For comparison:

§ LHC: Peak L = 1.5E34 cm-2s-1 à <PU> ≈30

§ UlJmate total integrated luminosity of HL- LHC era dependent on choice of peak running condiJons for luminosity leveling, which is informed by detector performance at high PU § Significant loss in performance at 200 PU due to influence of tracks from un- interesJng PU interacJons on measurements from ~1 interacJon we really care about in a given beam crossing

Chris Neu MIP Timing Detector Fermilab Director’s Review April 4, 2018 6

§ Reduced ability to separate PU interacJons from the hard interacJon at 200 PU § Every object vital to the CMS physics program suffers:

§ AddiJonal jets are associated with the hard interacJon, spoiling VBF-jet triggered and

Njet-categorized analyses

§ MET measurement suffers – affecJng resoluJon and tails, harming NP searches § LifeJme-based SVs become muddled with irrelevant tracks § Charged leptons appear less isolated, reducing efficiency for lepton-based

measurements and searches

Charge #1

Chris Neu MIP Timing Detector Fermilab Director’s Review April 4, 2018 7

§ Although the interacJons significantly overlap in space, they are more separable in space+Jme § With sufficient Jme resoluJon, current 3D PV idenJficaJon can be upgraded to a 4D fit, allowing for more effecJve cleaning of charged parJcle tracks from PU interacJons

Chris Neu MIP Timing Detector Fermilab Director’s Review April 4, 2018 8

§ The CMS MIP Timing Detector (MTD) is an apparatus that provides Jme-of- arrival informaJon for minimum ionizing parJcles (MIPs) with a resoluJon of beder than 50ps (KPPs: DocDB-XXXX) § The majority of parJcles produced in pp interacJons at the LHC are classified as MIPs

402.8 Requirements: Science Drivers

Charge #1

§ Other subsystems have limited Jming capabiliJes for MIPs – or none at all § Hence this addiJonal precision Jming informaJon can be used to help miJgate the impact of PU, providing improved performance at high PU and extending the CMS physics program in the HL-LHC era More details in Lindsey Gray’s talk in the auernoon Breakout Session

§ Granularity choice is a trade-

  • ff:

§ small sensors are less

suscepJble to Jme spread, leakage current, etc

§ small sensors inflate the total

channel count, increasing the data volume

§ Reasonable occupancy: 2-5%

§ operaJng point that avoids

significant impact from deposiJons in subsequent bunch crossings

§ Reasonable data volume:

§ ~4TB/s when read out upon

trigger w/ zero-suppression scheme

Conceptual Design: Granularity

§ ResulJng channel area:

§ BTL: 11 x 11 mm2 § ETL: 1 x 3 mm2 (x3 ganging for |η|<2.1)

Review History

§ MTD Technical Proposal (DocDB: 13511) submided to the LHCC in late November 2017

§ Seeking step 1 approval from LHCC to include MTD in Phase-2 CMS scope and proceed to preparaJon of

TDR

§ Timeline:

§ 4 December 2017: IniJal presentaJon of scope, definiJon, technical details and performance esJmaJons § 27 February 2018: Followup presentaJons addressing quesJons from review panel § 1 March 2018: RecommendaJons received

§ Response from commidee:

§ “The Jming layer design proposed by CMS is reasonable and is expected to fulfill specificaJons of the HL-

LHC running”

§ “There is experienced and enthusiasJc team of experts interested in developing and then construcJng

and operaJng CMS Jming layer”

§ “Based on the above we recommend CMS to proceed to develop Gming layer TDR with submission in

late 2018.”

§ RecommendaJons (abridged):

§ Extensive and large number of radiaJon hardness tests have to be performed on final elements of the

system, including sensors, electronics, power elements

§ Develop design in close cooperaJon with tracker and endcap calorimeter upgrade groups § Define specs for front-end ASICs and verify ASICs performance § Verify Jming signal stability in detecJon electronics of ~10 ps § Develop a full simulaJon of MTD, verify expected performance, further develop physics case of forward

layer
