ILC Plan for Two Detectors

• ILCSC Scope Document

– Scope under review

• GDE IR Design

– 2 20 mr recently changed to 14 14 mr

• WWS Arguments for 2 IRs/Detectors– Snowmass Proceedings

http://www.fnal.gov/directorate/icfa/LC_parameters.pdf

Case for Two Complementary

Detectors• Confirmation and Scientific Redundancy• Complementarity, Collider Options• Competition• Efficiency, Reliability, Insurance • Sociology, Scientific Opportunity • Historical lessons

• This will be expressed in the DCR

http://www.slac.stanford.edu/econf/C0508141/proc/papers/PLEN0059.PDF


Beyond the DCR

• GDE plans TDR at end of 2009• Experiments must remain on same timeline as

machine Detector TDRs ~2010 ?“synchronize” detectors with the machine

• TDRs require significant resources over time– 2 years? or more?

• How do we get there?– Downselect of detectors?– Authority to do this?– Intermediate step? CDR?

– Discussions in WWS, with GDE and ILCSC• Possibly CDRs in 2007/8

WWS R&D Panel reviewed the scope of the global program, and noted there was effort on most topics, particle ID other than muon, and forward tracking being noteable weaknesses

(we are planning to support some particle ID, and forward tracking) In general, all areas active.

Detector R&D - WWS

• R&D Panel Report – http://physics.uoregon.edu/~lc/wwstudy/R&D Report-fi

nal.pdf– Urgent needs require $32M and 1870 man-years over next 3-5 years - globally– Established support over 3-5 years $15M and 1160 man-years - globally– Translating man-years to dollars ($100k/man-year)

• $33M/yr established over 4 years, $22M/yr more required

– Support notably behind in North America and Japan

• Planning global review of R&D– With GDE R&D Board and WWS-OC




FY07 University Detector R&D in US

We are organizing ourselves in anticipation for increased funding in FY07 – discussed $3M with agencies(5 year R&D plan being developed by ALCPG)

Encourgement led to developing a proposal early for a few (9) high priority, urgent efforts (~$1M)followed by annual round for another $2M

Supplemental proposal prepared this summer1 – call for abstracts (received 22)2 – selection of highest priorities/urgent needs (9)

http://physics.uoregon.edu/~lc/lcdrd/supplement-06a.html


FY07 U.S. LCDRD Proposal FY07 proposals will be accepted for continuing and

new projects from DOE/NSF funding

One year proposals (third year of 3 year cycle)

Anticipated timelineDecember 15, 2006 – status reports

and new project descriptions dueMay – awards announced - revised budgets/descriptionsSeptember, 2007 – funded year begins

details will be posted on ALCPG web page


Test Beams

• The detector R&D program will need high quality test beams over the next few years.– WWS Test Beam Panel– Surveyed community on needs and facilties– Fermilab test beam – good for hadrons

• IMPORTANT Possible Special Role for SLAC– High energy electron beams– Note – requirements for detector tests different from machine

• ~ 1 particle per pulse

– Several projects are interested in this possibility• EM cal, tracking, vertex detectors

• Could be complemented by other interests (eg. Super B)

Detector Outline Documents

■ 4 Outline Documents were prepared in

Spring 2006 leading up to the Bangalore LCWS

■ Contents Description of the detector concept Performance estimates w.r.t. physics

benchmarks Required R&D and its status Rough costing estimate

See http://physics.uoregon.edu/~lc/wwstudy/concepts


FY06 review• 36 projects for FY06 from univ. and “small” labs• $2.828 M – limited by realization of limited availability of funds• 24 continuations of efforts supported in FY05• 12 requests for new projects.

• Review teams of two or three experts looking at each of the specific topics • Executive committee of six independently reviewing all of the proposals.

– Conflict of interest was considered carefully, and dealt with to avoid inappropriate influence in the review process.

• Evaluation of each proposal for the following factors:RATING: overall quality of the research plan and goals, and the strength of the team

to carry out the objectives (excellent, good, satisfactory, poor)

RELEVANCE: the relevance of the project to the linear collider detectors (critical, important, useful, irrelevant)

CONCEPTS: the importance of the work (except for the LEP - luminosity, energy, polarization proposals) to an active linear collider detector concept (critical, important, useful, irrelevant)

critical that project contributes to advancing detector technology for specific sub-detector capabilities of priority for the ILC physics program

Global Perspective (WWS R&D Panel)

US Detector R&D effort lags behind Europe

Fig 1. Urgent R&D support levels over the next 3-5 years, by funding country or region. 'Established' levels are what people think they will be able to get under current conditions, and 'total required' are what they would need to establish proof-of-principle for their project.


Detector Concept Report

• Physics• Concepts

– Based on four detector concept DOD's

The goal:– We can do the ILC physics– We have different and complementary solutions– We have a clear vision on how to reach the goals (R&D)– We have some understanding on the cost for these detectors

• Integrated presentation of Concepts• Case for Two Detectors/IRs
