The RDR and DCR

DCR is associated with the RDR: Due end of 2006 Detector Concept Report consists of

Physics section : ~50 Pages– Editors: Klaus Moening, Yasuhiro Okada, Joe Lykken, Mark O

reglia, Satoru Yamashita, Adbelhak Djouadi– Wiki page: http://www.linearcollider.org/wiki/

The Detector Section

Based on four DOD's and input from experts Prepared by 4 editors + authors to be enlisted Goal of the detector chapter: To demonstrate

that Detectors which can do the ILC physics are within

reach Several detector concepts are being pursued Advances in detector technology are needed The case for detector and concept R&D are made A good plan for the needed detector R&D exists;

additional support is required We have some understanding of detector costs There is a strong case for 2IRs and 2 detectors The world wide ILC experimentalists are united to

produce this document.


Activities of the Detector Editors

Bangalore, LCWS2006. Detector editor met for the first time and exchanged initial idea Met with physics editor Version 1 was presented at LCWS2006

Joined WWS phone meetings in April and June to discuss the DCR. Held phone meetings: 29 June & 6 July, and discussed the outline o

f the detector part Phone meeting with physics editors on 13 July Version 2 presented at VLCW06 Met GDE EC during VLCW06 DCR Detector Wiki page prepared






The Outline of the Detector Chapter

1. General Introduction2. Challenges for Detector Design and Technology3. Introduction to the Detector Concepts4. MDI Issues5. Subsystem Designs and Technologies6. Sub-Detector Performance7. Integrated Physics Performance8. Why We need 2IRs and 2 Detectors9. Detector Costs10.Future Options 11.Next Step12.Conclusion


1. General Introduction

3-5 pages, by Editors To describe

A brief description of the ILC Physics. Physics target of ILC detectors.– Baseline physics at 200-500 GeV – Extendability to 1TeV and/or optional running of /e, Zpol

e, W threshold etc. The functionality that an ILC detector should have:

– Tracking, vertexing, calorimetry, hermeticity, background consideration, trigger

Organization of this document


2. Challenge for Detector Design and Technology

10-15 pages: by Editors + experts To describe:

The needs for the detector performance– Jet energy resolution: Required lum. vs resolution.

+ Process: ZH, ZHH, SUSY, WW/ZZ. Resol. vs Lum– Momentum resolution:

+ Recoil mass of ZH llX : – Vertexing at ILC

+ H ccbar : – Luminosity, Energy, and Polarization measurements– The usual suspects at ILC:

+ Lepton ID, hermeticity, solid angle coverage

Experts work is essential: show results to each other and agree on results

3. Introduction to the Detector Concepts

By Concept Coordinators, ~5 pages per concept

Describe Concept of concept teams: Concept teams are not

collaborations. Motivation, rationale, design overview, performance

goals of LDC, GLD, SiD, 4th


4. MDI Issues

By MDI panel, together with concept experts: 10-15 pages

Describe the ILC environment, Backgrounds, and the Machine Detector Interface, such as Timing and bunch structure, impact on design Background evaluation, Robustness and timing requirements. Describe based on the base line configuration of 2mrad and 20

mrad. And show that detectors can work with this configuration. Description of other configurations such as 14 mrad, etc, are des

cribed as options

2mrad/20mrad 14mrad/14mrad if the base line is changed.We nee new inputs for 14mrad case


5. Subsystem designs and technologies

By R&D panel + editors Describe how each subsystem looks like, what kind of tec

hnologies exists for them, technological challenges, and required R&D to achieve goals.

Anticipated Subsystems and page length1. BeamCAL (~3page)2. Vertex Detector (~7pages)3. Tracking: TPC/Si Hybrid(~5 pages),

Si Monolithic (~5pages)4. Calorimetry: Ecal&Hcal ; describe major technologies and concept

s (15~20pages)5. Solenoids(~ 5pages)6. Muon System(~5 pages)7. LEP(~5pages)8. Electronics and DAQ(~5pages)


6. Sub-Detector performance

10-15 pages: by Editors with Concept Reps. Based on results from Concepts and other studies Pickup typical results Describe typical performances such as

Tracking performance: efficiency, purity, solid angle coverage, momentum resolution

PFA performance Vertexing performance Lepton ID

Results should be based on FULL MC. New work is required.


7. Physics Performance

~ 10 pages: by Editors + Concept Reps/Experts. Fast MC result will be in physics part Show results based on full MC

To support results by fast MC New work is needed / contributions are highly welcomed

We will incorporate as many new results as possible We need them soon

At least, we will show that There are efforts to study physics performances based

on full simulation Some preliminary results on some process supports

arguments in physics part


8. Why we need 2 IRs and 2 Detectors

3-5 pages : By 2IR task force Based on document at http://www.slac.stanford.edu/econf/C0508141/proc/papers/PLEN0059.PDF

New arguments are welcomed

9. Detector Costs

~5 pages : WWS Costing panel + WWSOC Describes

Methodology: Be consistent with the Acc. Costing Based on the information from the concepts "Average" costs


10. Future Options

5-10 pages: Editors with inputs from experts Describe

Overview of option physics Detectors are optimized for e+e- physics, but will be

modified if LC500 and/or LHC results motivate to go for option physics.

Needed changes to detectors, and needed R&D


5 pages : Editors + WWSOC Describe

Steps toward detector TDR Need discussion in WWSOC

Plan after DCR; – Detector optimization: better understanding of

detector performance based on full simulations.– Subsystem R&D : Proposed detector subsystem

technologies have to be confirmed by R&D.– Plans of concept teams…

11. Next Step


12. Conclusion

2-4 pages: by Editors Conclusion would be

Based on detector concepts, we showed that detectors which can do the ILC physics are within our reach

The case are made for the detector concept R&D and technology R&D.

We have some understanding of detector costs There is a strong case for 2IRs and 2 detectors


Time line to prepare the detector chapter

Time line: At Vancouver:

– Propose the outline– Authors are nominated/selected

By End of September– First draft including major part of figures collected.– Some figures will be preliminary

By End of October=ECFA meeting at Valencia– Combine drafts, make a balance, editing
