Upgrades Week – November 2011 Goals for the November Upgrade week

Schedule for Phase I Work towards TP for Phase II

November 2011J. Nash - CMS Upgrades1

CMS Upgrade Weeks This is the 12th CMS Upgrade “event” Started with Upgrade Workshops

First in Feb 2004 We have held two previous workshops at FNAL

(2008,2009) These have been very successful as workshops Lots of opportunity for discussion Away from CERN we tend to allocate more time for

discussion

CMS Upgrades Project Status: We have been focused

on producing the Technical Proposal for the first decade of operation Now this part of the

project is moving into construction

We need to begin to prepare a technical proposal for the second decade of operation Increase R&D Take some strategic

Calorimeter Trigger Designs

• Several prototype uTCA trigger cards have been built and have been shown to work. Working demonstrators at the crate level exist also.

• Two calorimeter trigger architectures are under consideration.• We have organised a review for the two Calorimeter Trigger

architectures. The aim of the review is:1. to select the architecture which best serves CMS for the next

decade.2. Produce a plan for the two relevant groups (Wisconsin-

Imperial) to work together towards the final design.

ECAL–Trigger Interface - OptoSLB

13

Converts ECAL copper signals to 4.8 GBps optical and allows to keep using the current ECAL Trigger electronics after 2014.

Bought 4 optical devices for evaluation. Design effort for the card has started. First prototypes have been promised late in 2011 early 2012. Production should start in 2012.

Goals for the November Upgrade Week Refine phase I schedule

Tasks for each of the projects given as homework before the workshop

Use the workshop to refine these schedules, and to look at the dependencies between systems

Come out of the workshop with the start of an overall project schedule To be refined and maintained as we move forward


Project Breakdown Define the appropriate high level project tasks

(eg – Front end electronics, cooling…) We will use these tasks as the units for

reporting and tracking the progress on the project

This was very successful during the build of CMS

Important to break the project down in an appropriate way This certainly depends on the project, so no top

down overall requirement for the shape of these


Milestones Define a set of milestones for each of the

project tasks Examples

Prototypes ready, TDR ready (the LHCC are waiting for these…), production review, Commissioning

Declare them (at a defined level) to the upgrade project

Discuss how we will monitor and present them


Dependencies between projects Look at Links to other projects, and the

machine schedule and how they affect the milestones Take into account links between projects Take into account possible shutdowns now being

considered i.e. TS or LS2 installations We would like everyone to take the latest

“official” schedule for the machine as the basis for when the shutdowns could be

Allow for the possibility of an extended Technical Stop before LS2

Goals for November workshop - Phase II Develop a plan for proceeding with the phase II

project We will need to produce a technical proposal for

phase II (CMS2) on the timescale of around 2014 We need to take strategic decisions which will shape

the future CMS detector These decisions need to be taken by CMS as a whole

with the goal of producing the best instrument for physics measurement at a high luminosity LHC

Proposal: Create a CMS2 project review group High level strategy group Not based in sub-detector Reports to Upgrade Management, and ultimately to the CB

High Luminosity LHC (HL-LHC) Goals for the High Luminosity Running after

the third technical stop Integrated Luminosity 3000/fb

This to be collected at up to 300/fb-yr Detectors need to cope with high pile-up

Up to an order of magnitude greater than what we are seeing now

Detectors need to cope with high radiation Up to an order of magnitude greater than we

expected for LHC operation

The tracker is the key detector which will require upgrading for SLHC Phase 2

Level 1 Trigger

The trigger/daq system of CMS will require an upgrade to cope with the higher occupancies and data rates at HL-LHC

One of the key issues for CMS is the requirement to include some element of tracking in the Level 1 Trigger One example: There may not

be enough rejection power using the muon and calorimeter triggers to handle the higher luminosity conditions at HL-LHC

Adding tracking information at Level 1 gives the ability to adjust PT thresholds

Single electron trigger rate also suffers Isolation criteria are

insufficient to reduce rate at L = 1035 cm-2.s-1

Level 1 Trigger has no discrimination for PT > ~ 20 GeV/c

very extreme environment High pileup implies

high occupancy and in some areas high radiation exposure

Technical Proposal in 2014? How long should we spend working on R&D

We have been conducting R&D since around 2006 At some point we need to make decisions about

what directions we will take, and move from R&D phase to a proto-typing phase

Time needed for Phase II R&D There were about 10 years of R&D for the initial

build of CMS Followed by

2 years proto-typing 5 years production-install-commission

To get a new big detector ready by 2022 the timescale of 2014 for a TP just fits. The detectors for phase II are the same scale as major

sub-detectors were for the LHC, and technically more complex

We will need to ensure we are doing enough focused R&D to be ready to make designs and decisions.


Tracker Phase II R&D Some of the earliest R&D was on how we

could build a new tracking detector This is an extremely challenging task, and will

certainly have a major impact on our ability to do ANY physics in a High Luminosity Environment

R&D in the tracker project is progressing well, and the Tracker has prepared a phase II upgrade organization

Tracker R&D - cooling


Tracking Trigger Task Force Study how a Level 1 trigger could be built

using the tracking detector as input How many Pt modules needed for a Level 1

Trigger? Where do these need to be placed?

At the first FNAL workshop we kicked off the work of this task force with some radical layouts to be studied in order to help answer some of these questions.


Tracking performance also studied


Studies of different layouts now well advanced


Forward Calorimetry task force The second Task force has been asked to

study calorimetry in the forward region What are the requirements from physics for

performance of the forward calorimetry system in the HL environment?

How will the current detectors perform in the HL environment?

How could a new system be constructed?
