Technology choice
George Kalmus will explain the ITRP process
and the give their recommendations.
ILCSC in Beijing accepted these recommendations
and chose to call the collider the ILC.
It will use cold technology, but the whole design
will be revisited. It need not look like TESLA.
First meeting of accelerator designers from
participating labs will be in KEK in November,
maybe straight after the ACFA Taipei workshop,
i.e. from 13/11/04

Designing the ILC
ILCSC+ICFA plan a Global Design Initiative (GDI)
to begin early 2005, hosted by a substantial laboratory
for logistic support.
(9 labs have bid to be host; selection panel appointed,
European members R.Eichler and S.Bertollucci)
There will be a Central Team (selection panel for its
leader appointed; Europeans A.Wagner and DJM)
with three Regional Teams. An MOU is being drafted
for agreement between the GDI and the participating
Laboratories.

Other strategic developments(1)
Funding Agencies’ meetings (preparing govts. for ILC)
Next will be September 16/17 at CERN,
specifically to follow up on technology choice.
Directors of the main ILC Labs will be invited.
CERN Council 19 July Rome statement, inter alia,
- recognises and encourages a TeV LC
- suggests taking stock of LHC and accelerator
R&D results by 2010, and production of new
assessment of physics and technology.
- suggests GDI to 2007 should be “light”
NOT a new ITRP,
say most participants.
David J. Miller @ Durham 1/9/04
It is!

Other strategic developments (2)
EUROTeV. Very important to have EU support,
and significant CERN input. More from Eckhart Elsen.
UK accelerator physics inititiative. LC-ABD funded
by PPARC and CCLRC for a study of the beam
delivery system and instrumentation.
(Grahame Blair will talk about both the above)
Also two new Accelerator Centres in UK;
* Cockroft – Manchester, Liverpool, Lancaster, Daresbury.
* Oxford/RHUL.
Both will be running courses and looking for international
Collaborations.

ECFA
Organizing the Global
Experimental Program
The ILCSC has asked the Worldwide Study, as its Physics and
Detectors Subcommittee, to develop a plan for organizing the
experimental program in parallel with the GDI for the
machine.
This plan should include the following:
1. Ensure that at least two different detector concepts are developed;
by worldwide teams which will:
- prepare CDR(s) on concepts, by ~2006;
- be ready to form the cores of the collaborations when funding
is in place and bids are called for.
2. Encourage and coordinate inter-regional R&D on essential detector
technologies, and give peer-reviewed recognition to nationally funded
R&D programmes as part of the worldwide project.
3. Make sure that vital questions of machine-detector interface and
beamline instrumentation are as fully supported as accelerator
and detector R&D. This will involve close links with the GDI.

Response to ILCSC request
To members of Study (you) and ILCSC
WWS Organizing Committee proposes to:
• Recognize and coordinate studies on whole detector
concepts, and work toward interregional detector TDRs,
including a cost document available at the time of the
Accelerator CDR.
• Interface with GDI, especially on Macine-DetectorHOW?
Interface issues.
• Keep a register of R&D relevant to LC experimental
programs, identify those that are vital or missing, and
ensure peer review of R&D proposals.
• Organize interregional meetings and workshops.
• Report to ILCSC and ICFA on the matters above.

Discussion in the Community(1)
HOW?
• At the Paris LCWS 2004, the ILCSC charge was
presented to the community in the opening talk
by J. Brau, and in a special session by DJM,
followed by a discussion.
• Following the Paris LCWS (April) and leading up to the
Victoria American Linear Collider Workshop (July), the
WWS Organizing Committee drafted and distributed a
proposal document, which included the creation of a
small executive committee (~ 6 members, the Global
Experimental Commission - GEC), which would oversee
a costing document and detector R&D, receive the
detector LOIs, and execute other tasks.
David J. Miller @ Durham 1/9/04

ECFA
Discussion in the Community(2)
• Draft proposal was circulated in the community.
Lots of feedback.
• Community saw GEC as creating a confusing boundary with WWS
Organizing Committee. Could weaken WWS, which is an effective
bottom-up representative of all physicists interested in LC.
WWS has worked effective to coordinate global activities.
• Instead, now propose that WWS Organizing Committee appoints
panels to perform necessary tasks, and retains oversight.
(Not necessary to create GEC)
• WWS-OC revising document – will circulate for more discussion, then
submit to next ILCSC meeting (November at KEK?)
David J. Miller @ Durham 1/9/04

ECFA
Proposed Panels
• Costing panel: Request inputs from the teams studying
each detector concept, ensure the same costing basis, and
edit into a single document to be included with the
accelerator CDR. Then the panel will stand down.
• Detector R&D review panel: Maintain a register of relevant
R&D, identify vital or missing activities, arrange for peer
review of proposals, and endorse approved programs to
funding agencies when requested. This panel will stand
down when the detector proposals are finalized.
• MDI panel: Liaise with GDI to coordinate MDI issues
between accelerator and experimental teams, and ensure
that essential MDI R&D is done. The panel will stand down
when the global lab takes over this role.
• More panels to be appointed as needed.

GDI Milestones
• 2004 – ITRP Technology
Recommendation
• 2005 – Accelerator CDR
• 2007 – Accelerator TDR
• 2008 – LC Site Selection
• Site selection + 1 year
David J. Miller @ Durham 1/9/04
Proposed Milestones
Experimental Program
• Single preliminary costing
document for at least one wholedetector concept produced
by WWS Costing Panel
• CDR’s from each detector concept
team (expect some individuals to
sign multiple CDRs) received by
the WWS OC
• Collaborations form and submit
LOIs for proposal to the Global
Lab (or GDO?)
• Global Lab selects experiments
and asks for 2 TDRs

R&D collaborations (A, B, C etc.) exist in their own right.
Concept studies (1, 2, 3, 4 etc.) draw on them as needed
– at this stage.
CONCEPT STUDIES MUST BE INTER-REGIONAL
R&D programmes should try to be.

Globalising the Concept Studies
Friday afternoon plenary this week is part of the start
(with Victoria and Taipei):
Harry Weerts and John Jaros here to present
the Silicon-tracking detector concept.
Extra meeting Saturday afternoon to enlist participation.
Satoru Yamashita and Ties Behnke will present
two alternatives for a Large Volume Gaseous-tracking
detector concept, growing out of former TESLA,
JLC/GLC and American “Large” designs.
Need to work out how these (and maybe more)
concept teams are organised, how they input to WWS
costing panel, how they develop towards CDRs.
Discussions in Thurs morning Detector Performance
parallel session and Friday afternoon plenary.

Other special sessions here
Thursday afternoon, “Test Beams for Calorimetry+”
interactive video conference with Asian and American
participation (c.f. previous detector R&D conferences
including Calorimetry at Montpellier.)
VERY IMPORTANT BECAUSE THE LABS NOW WANT
STRONG ARGUMENTS FOR SPENDING MONEY
ON TEST BEAMS. THERE IS A NEW REPORT ON
TEST BEAM AVAILABILITY
http://www.linearcollider.ca:8080/lc/vic04/abstracts/detector/testbeam/wwlctb_working_group.doc
Can we agree a strong brief message to ICFA, summarising
the need?

ECFA
Cosmology and the Linear Collider
New working group; very successful in ALCPG.
Manuel Drees and Abdelhak Djouadi convening here
(except the UK failed to give Abdel a visa!)
We need an experimental convener, and ideally an
astronomical cosmologist (volunteers and/or
nominations please)

Future workshops
ACFA workshop Taipei 9-12 November
Next LCWS will be at Stanford in March/April
ALCPG also proposing a 2-week meeting in the
Rockies in August, with strong worldwide participation
(talk to Jim Brau about ideas).
When should 2005 ECFA workshop be?
June, October, November?
OC+conveners will discuss Friday lunchtime.

Future ECFA Study
Needed as ILC activity grows, but present Study
ends Spring 2005.
Must make proposal to September RECFA, so they can
send a resolution to December PECFA. Must also draft
at Friday’s OC.
Need nominations for new chair. Rolf Heuer will
collect and pass to ECFA chair.

Have a good workshop!
Your first and last speakers
(DJM and Brian Foster) are
both natives of Durham county,
but I’d like to end with a
much more powerful local
influence; our patron saint,
Cuthbert (“Cuddy”),
holding a model linac
in one hand and blessing
our efforts with the other.
It’s good to have both
Gudi and Cuddy on our side.
