From last RRB: Challenges Ahead, Task “Pileup” in 2017

  • Execute the Extended Year End Technical Stop (EYETS) –

installation parts of the Phase I Upgrade

  • Produce extensive physics results on full, larger than

expected, 2016 data set

  • with a computing budget that is rising less than the data

volume

  • Do FOUR Phase 2 Upgrade TDRs (Tracker, Barrel

Calorimeter, Muon detectors, Endcap Calorimeter) and TWO Interim design documents (Trigger, DAQ/HLT)

  • Take high quality data in 2017 with rising luminosity and

analyze it quickly and efficiently

  • Continue to build the remainder of Phase I Upgrade

Management Evolution

  • September 1 is the date when new appointments go into

effect for coordinators, system managers , spokespersons, CB chair team, as well as corresponding deputies and many conveners, L2, and L3 managers

  • The new Management Board Organigram is on the next

slide

  • The previous one is in backup
  • “Other States B” is a new category in the Regional

Representation that is driven by expansion of CMS member institutions that are not from full CERN Member States

  • Upgrade Coordination will be stable through the completion
  • f the TDRs and costs but will have some changes that will

be up and running well before next September

Expanding and improving CMS

Engagement Office was established about 10 months ago. Led by Kerstin Borras

Mandate: help and support CMS, on the side of the institutes as well as on the side of the

projects and coordination areas, to cope with the unprecedented list of tasks to be

  • accomplished. The Engagement Office is charged to work with all stakeholders, including

existing committees and bodies, to identify areas of concern and to develop solutions.

 4 main areas of activities:

1) Institute Engagement

  • For New institutes: Set up all procedures and helping new institutes phasing in to CMS
  • For Member institutes: Provide assistance to institutes experiencing problems to phase into

CMS and to contribute at an appropriate level

2) Coverage of Tasks, Remote Contributions, Efficiency & Sustainability 3) Coordination of EPR (service work) and related items 4) Measures for Diversity, Young Scientists, Career Evolution

Operations: 2017 Startup after Extended Year-End Technical Stop (EYETS)

RRB45 24/10/17 12

slide-13
SLIDE 13

Operations Status

  • From my Feb 21, 2017 report to LHCC 129, about startup of

the Pixels

  • “Startup Implications: We will lose some luminosity at the

beginning of the run since some commissioning must be done with collisions . We expect to “effectively” recover it through higher efficiency, better resolution, and lower fake rate.

  • Pixel Commissioning seemed more difficult than

anticipated

  • Timing problem between Layer 1 and Layer 2
  • Layer 1 Readout chip efficiency problem
  • Higher noise in Layer 1 than design goal
  • Single Event Upsets (SEUs) from the TBM
  • This led to extra commissioning time early in run
  • Dead time due to stuck modules has been “mitigated” by

system of local resets which we have been steadily improving

  • Some down time because Power cycling is necessary to

clear some stuck TBMs (SEUs)

  • We have recovered operational efficiency
  • even at high luminosity
  • Performance is better at this early stage than the best (final

re-reconstruction) we had in 2016 data even at 1.8E34, achieved in 2017

RRB45 24/10/17 13

slide-14
SLIDE 14

Data Recording Efficiency

24/10/17 RRB45 14

  • The recording efficiency so far in 2017 is 89.8% as compared to 92.5% for 2016.
  • This reflects the period to commission the pixels and to resolve the problems
  • This has improved lately, to mid 90’s, even in very high luminosity running
  • I had expected to lose about 10% of the data for the run, but the actual loss is ~1 fb-1, or

2.7% “so far”, much, much less than we will gain in performance

  • We are now running leveled at 1.5E34 leveled with the machine over 1.8E34 (but fewer

bunches, 1868) and recently up to 2.2E34

  • Pileup can be as high as 50-60
slide-15
SLIDE 15

Selected performance results: Pixel Hit Efficiency

  • Dynamic inefficiency is much smaller than in the old detector
  • … but expected to be even smaller: ~98% at 2*1034cm-2s-1

Pixels after Technical Stop 2 (TS2) (week 39)

  • At TS2, we were doing well with the pixel detector
  • Systems of soft resets and power cycles kept efficiency high
  • The detector was keeping up with very high luminosity
  • After TS2, we encountered a new problem (about two weeks ago)
  • After a power cycle to free stuck TBMs, DC-DC converters began to

die permanently

  • This reduces our ability to deal with stuck TBMs
  • We are attacking this problem vigorously, but so far do not

understand it

  • While we are able to run through 2017 with only a slight loss of

efficiency, efficiency may be a problem if 2018 brings very high luminosity

  • We have to consider the possibility that we will need to access the

detector in the YETS and, if granted, this could add time to its overall length (which we will of course try to minimize)

HF Phase 1: Summary

24/10/17 RRB45 18

  • New handles to achieve noise reduction are in use:

– PMT with dual- anode readout and TDC information

  • Smooth installation and operation

– All 3456 channels, ADC&TDC, working

  • Substantial rate reduction for MET paths achieved

 The HF Upgrade is done

slide-19
SLIDE 19

Hadron Endcap Calorimeter (HE) Phase 1 Modified Plan

  • Silicon Photomultipliers (SiPMs) are a new technology

that provides superior performance than the Hybrid Photodiodes used as the photosensors for HB and HE

  • 3X the quantum efficiency, high gain  better S/N, no

High voltage necessary, works in strong B fields, low cost,

  • Decided not to install the full 36 Readout Boxes in

2017

  • Degradation of the signal with radiation exposure

lower than projected  not needed for the 2017 run

  • We did Install ONE Readout Box (HEP17), initially as an

installation test, but after detailed review of impact on

2017 analysis kept upgraded HEP17 in for collisions We learned a huge amount about installation, commissioning, performance, which is far superior to current system.

  • Based on HEP17 success, we are considering the

installation of the full HE upgrade in YETS 2017-18 (normal winter stop)

  • Otherwise must install in LS2 along with Barrel

Hadron Calorimeter (HB)

Run 2 Schedule

21 RRB45 24/10/17

  • 16L2 led to luminosity on the low side in the first part of 2017
  • Measures discovered led to higher luminosity, but also with higher pileup
  • Peak luminosity limit achieved is ~2.2e34 !
  • 2018, after 16L2 is remedied, is expected to be a heavy luminosity

production year so will have well over 100 fb-1 from Run 2

  • ~3% of integrated luminosity expected by the end of the program

YETS

slide-22
SLIDE 22

YETS 17/18 and LS2

  • YETS 17/18 is “normal” 13-14 weeks
  • HE full upgrade installation proposed
  • Some normal repair and maintenance
  • Possible work on DC-DC converters
  • LS2, partial list
  • Assuming the Layer 1 ROC problem is solved and ROCs are
  • btained in time, build new modules, with the new TBMs and

refurbish Layer 1

  • DC-DC converter repair might require significant effort depending
  • n what we learn
  • HB Phase 1 upgrade – replace HPDs with SiPMs, change

longitudinal segmentation, add better timing

  • Would have also to do HE upgrade if not done in YETS/17/18
  • GE1/1 installation (Phase 2 Muons)
  • Forward CSC work (Phase 2 Muons)
  • Phase 2 infrastructure upgrades and many other activities

Computing

RRB45 24/10/17 23

slide-24
SLIDE 24

Computing Status and Prospects

  • CMS adapted well to the unexpectedly large data harvest in 2016
  • Early in the 2017 run, LHC problems resulted in lower luminosity, but

not lower data volume (fewer buncheshigher pileup)

  • In the last month, there has been a huge increase of LHC performance
  • 8b4e + BCS + beta* of 30 cm => per bunch luminosity would scale to 2.3e34 in a full

machine

  • PU (which is 35 averaged over the fill) well over 40, and 55 for long periods
  • LHC turnaround time as low as 2 hours
  • All of this has put pressure on the Tier-0 system – load depends
  • n ~ PU * LHC Efficiency * HLT rate
  • 2018 will be a “luminosity production year”, expected to generate a lot
  • f data and there will a legacy re-processing of all Run 2 data starting

in 2019

  • ECOM17: Grounds up study of computing with time frame of next few

years

  • Chaired by T. Boccali (Pisa) and F. Wuerthwein (UCSD)
  • Their initial report has now been approved and implementation has started
  • A similar group may now be formed to look at longer term (HL-LHC) issues

Tier-0 status

  • Tier-0 under pressure

after the LHC TS2

  • Change in daily

produced output evident

  • CPUs are holding up –

up to 1 day of prompt delay over the 48h at times

  • Disk buffers and

transfers at the limit (systems provisioned for lower PU)

  • Still, all ok with

increased human effort Daily Tier-0

  • utput; clear

change of pace after TS2

CPU Task Force

  • Interim report: Of the 2 sources of inefficiency we have succeeded

in tuning the submission infrastructure such that the CPU inefficiency from it is only 3% from a high of 20%.

  • Over the last few weeks we have turned our attention to the second

source, application (production and analysis) inefficiency.

Tracker HL-LHC Upgrade

  • “In summary, the Tracker Upgrade Project pushes tracker

designs into a new paradigm with a scope that is justified in terms of technical realization as well as physics

  • performance. The design is bold, but no technical

showstoppers have been identified. It is critical that the remaining R&D be supported as strongly as possible and that appropriate funding for the R&D efforts be provided. Strong oversight is required to keep the schedule. Based

A Snapshot of the CMS Phase 2 Upgrade Cost - I

  • The core cost of the CMS Phase-2 upgrade is currently estimated

at 278.9 MCHF including:

1) The scope of the 2015 Technical Proposal 264 MCHF

  • Improved quality of estimates prepared for the system TDRs or Interim

TDRs, including several design optimizations for performance versus cost

  • Compares to 265 MCHF in TP (new cost of 264 MCHF includes the effect of

updating to 2016 currency exchange rates: a 3 MCHF increase)

2) A new Minimum Ionizing Particle Timing Detector (MIP-TD)

  • f 14.9 MCHF cost
  • Additional mitigation of collision pile-up through precise time association of

tracks to vertices will improve all physics object reconstruction and enable CMS to fully benefit from the highest luminosity potential

  • We are studying whether this can also lead to a significant impact on HL-

LHC computing

RRB45 24/10/17 41

The CMS Phase-2 upgrade expected funding is established at 275.6 MCHF

  • ≃ 11.9% of the funding is at the

level of requests to Funding Agencies (FA) (grey)

  • ≃ 51.5% is being processed by

FAs as a target (yellow)

~88% is considered highly likely

slide-43
SLIDE 43

A Snapshot of the CMS Phase 2 Upgrade Cost – III

43

The Phase-2 upgrade cost, including the MIP-TD, currently exceeds the expected funding by 3.3 MCHF (1.2%)

  • 1.2 MCHF of this arises from missing contributions to Common Funds,

expected to be forthcoming but not considered guaranteed

  • Several possibilities are considered to overcome the over-budget.

Particularly technical choices still to be made may allow cost reductions up to 3% of the total cost, and most will be known in 2018. The present best candidates are:

  • The HCAL barrel tile replacement of 1.9 MCHF, current information indicates

that this is most likely not needed

  • A new scheme with commercial grade power supplies for the major detector

systems is actively investigated and considered a good candidate to save ≥ 2 MCHF

  • The target to confirm these two cost reductions is early spring 2018

24/10/17 RRB45

slide-44
SLIDE 44

44

Cost and funding alignment of all systems is at a % level of the total funding

  • Funding relocations are however needed to cover all system upgrades
  • This requires flexibility to adjust FA deliverables to different systems in order to cover the best possible

scope for physics reach. This process is ongoing

To be ready to react in case of a funding shortfall, CMS is preparing mitigation options. This will accompany the next funding plan iteration by Apr 2018 RRB

  • A level of 10% is consistent with the current knowledge of discussions at FAs
  • Several cost reduction options have already been identified:
  • Technical choices still to be made in the next year may allow additional cost reductions up to 3%
  • Descoping of system elements are being considered, they should minimize operation risks and loss of

performance, and preferably be recoverable

Summary and Outlook

  • The EYETS went well
  • We encountered problems with the new pixel detector but are

taking excellent data with it

  • Physics results continue to be excellent with much exciting

analysis ahead for 2016 data and with an equal or greater amount of new data from 2017

  • Computing navigated the challenges of the larger than expected

2016 data set and performed very successfully in the campaign for the winter/spring conferences and so far in 2017

  • Plans are in place for the next few years.
  • The Upgrade Document preparation is on track and has acquired

a new element in the MIP Precision Timing Detector

  • The Tracker (inner and outer) received scientific and technical

approval from the LHCC and is now being reviewed for cost by the UCG/LHCC

Phase 1 Pixel Detector

Pixel Upgrade:

  • Baseline L = 2x1034 cm-2sec-1 with 25ns BX  50 pileup (50PU) with very small efficiency loss
  • Tolerate L = 2x1034 cm-2sec-1 with 50ns BX  100 pileup (100PU) with reduced performance
  • Survive Integrated Luminosity of 500 fb-1
  • Same detector concept: higher rate readout, data link and DAQ w/ less material forward
  • More Robust tracking : 4 hit coverage; 3 layers/2 disks to 4 layers / 3 disks (can compensate point

losses in strips)

  • Inner layer closer to beam  Better primary and secondary vertex resolution

(To be installed in EYETS)

slide-55
SLIDE 55

HF: Forward Hadron Calorimeter

  • New thin-windowed, metal envelope Multi-anode PMTs

were installed in LS1

  • Less glass eliminated sources of Cerenkov light that

were causing large pulses  Fake MET

  • Multianode feature is the next step in this process since

true signals are symmetric and false ones are not

  • Anodes currently ganged in “adapter board”
  • Timing is also different and a TDC is part of the new

readout, implemented in the new QIE board

  • Status (Led by University of Iowa)
  • PMT box rework started – December 7th 2016
  • PMT box rework completed – February 10th 2017
  • All PMT boxes installed – February 16th 2017 (three

weeks ahead of schedule!)

Summary of the Status of Phase I Upgrade

  • Most work is now complete
  • Muon and Infrastructure Upgrades were done in LS1
  • E.g. YB4 (beam halo shield), CO2 cooling, beampipe
  • We used the upgraded Level 1 Trigger starting in 2016
  • Trigger was installed in 2015 and operated parasitically
  • HF was started in LS1 and completed now in EYETS
  • Pixels are now installed
  • HE construction is finished
  • All equipment is at CERN , tested and ready to install
  • Installation will likely be in 2017/2018 YETS
  • HB will be done in LS2 as planned
  • Very similar to HE
  • Should be at CERN well in advance of LS2 and installed

and checked out well before resumption of running

Top pair rate is > 10 Hz, enabling us to address much more precise questions

  • Single and double differential cross

sections

  • Rare (FCNC) decays
  • CP violation (a beginning)
  • Width and more complex methods

for measuring the mass

  • Top pair production at 13 TeV CM

energy is mainly (80%) produced by gluons, providing important information on the gluon distribution at relatively high xF, up to ~0.25
