For linear colliders it has mostly been good Snowmass consensus ECFA panel report Acfa report HEPAP recommendations German Science Council The work of the LCWS series and the inputs from ECFA/DESY and the other regional studies have been vital to making the case. BUT WE HAVE NOT GOT APPROVAL YET. The hardest parts have still to come. Many of them are down to us. Physicists worldwide want a single international machine in the 500 GeV to 1 TeV range; expeditiously. Physicists’ Consensus

In so doing the Committee will give particular attention to Outreach, Science, Technology and Organization of the LC project. The Steering Committee will report to ICFA. ILCSC

It is particularly important that the initial energy, the initial operations scenario and the goals for upgradability be properly assessed. 3.Monitor the machine R&D activities and make recommendations on the coordination and sharing of R&D tasks as appropriate. Although the accelerator technology choice may well be determined by the host country, the ILCSC should help facilitate this choice to the largest degree possible. 4.Identify models of the organizational structure, based on international partnerships, adequate for constructing the LC facility. In addition, the ILCSC should make recommendations regarding the role of the host country in the construction and operation of the facility. 5.Carry out such other tasks as may be approved or directed by ICFA. Mandate of the ILCSC

To assess potential of each design for reaching higher energies above 500 GeV. To establish for each design the R&D work that remains to be done. To suggest future areas of collaboration. 3 sub-panels doing the detailed hard work: Technology, Luminosity performance, Reliability and Operability

(Maybe a useful language for detector R&D too) R1. More R&D needed for feasibility-demonstration of machine. R2. R&D needed to finalise design choices and ensure reliability. R3. R&D needed before starting production of systems and components. R4. R&D desirable for technical or cost optimisation TESLA 500TESLA 800 NLC/JLC(X) 500 NLC/JLC(X) 1 TeV R1 - none35 MV/m Accel. structures Higher gradient SLED II RF compression R2 All machines need R&D; especially Damping rings, Low emittance transport, Reliability, Availability, Operability. + Specific needs. R3 and R4: many items for all machines; much in common.

If have to launch a project today for 500 GeV, TESLA is only one with “essentially” proven performance specifications for main linac. By end 2003 will know if TESLA can reach 800 GeV at 35 MV/m (with extra RF- and cryo- power) By end 2003 will know if JLC/NLC(X) 500 can reach main linac RF specs. It should then be easier to reach an objective decision - including other merits of the respective designs.

Detector R&D report now on the web, plus webpages linking to ongoing R&D programmes. Still quite a few uncovered topics (e.g. FTD). Worldwide video meetings planned, the day before regional workshops: Vertex detectors; 8 Jan. 2003, from Arlington TX Tracking; 31 March 2003, from Amsterdam Calorimetry; Summer 2003, from somewhere in Asia

The “10 page” document. ILSC asked LCWS 2002 to set the “scope” for the machine. Much debate at Jeju about what they wanted and what was appropriate from the whole World LC intended-user community. In response to the request, we* are preparing a statement of about 10 pages which should - summarise the physics aims of the proposed International Linear Collider, drawing on existing reports including TDR, Snowmass and ACFA books. - outline the kind of detector(s) to be built by international collaboration, - state the desirable properties of the machine, and the benefits which will come from the options we have studied (e.g. , GigaZ, polarised e+). * Drafting panel: Paul Grannis, Francois Richard, Sachio Komamiya, Takayuki Matsui

We believe that this international endorsement will have an impact on government decision makers. Please read it and help us improve it. Worldwide Study Activities..our “10 page” document, continued At Jeju we did not feel that the whole membership of the World Study could agree the precisely prioritised scope of the baseline machine - energy, luminosity, which options in which order (e.g. 2nd intersection; gamma-gamma; e+ polarisation; GigaZ etc. etc.) - though the need for each is explained in our document. Instead the ILCSC will form a panel with 2 members per region (ours to be nominated by ECFA) to propose a definition of scope for ILCSC to adopt. It should advise on which choices must be kept flexible to respond to Physics results.

Scientific representatives of funding agencies invited to the final day for these reports. Will decide at OC+Conveners and Contactpersons meeting this Monday if Amsterdam will produce paper proceedings. Continuation as the “ECFA Study” requested to Spring Essential to keep up momentum, tackle outstanding problems and play our part in European and International Steering. Decision at RECFA+ECFA meetings, November 28/29.

Joint group on LHC/LC relationship has an important and difficult job; to make the case as strongly as possible without overstating it. Tools still need a lot of hard work. Many detectors not properly included. GEANT4 not fully operational. What scope for sharing effort with other regions? New problems for Machine Detector interface - see Nick Walker’s talk. Rolf Heuer will announce a Global Detector Network. Groups encouraged to give short reviews of Jeju for those who missed it.
