International Linear Collider Workshop 2008
LCWS08 and ILC08
November 16-20, 2008
University of Illinois at Chicago

Dear colleagues,
The fourth General ILC Workshop (ILC08) will be held at the University of Illinois, Chicago fromSunday, November 16th until Thursday, November 20, 2008. The workshop will run in parallelwith the LCWS 2008 physics and detector workshops, with which ILC08 will have several joint
plenary sessions. As in the past, our plans are to make these joint workshops a strong focus forthe global ILC community.
The deadline for reduced registration is October 1, 2008(http://www.linearcollider.org/lcws08/index.html )The workshop comes at the end of a busy and eventful year for the GDE and will be its main(now annual) collaboration meeting. Following on from the smaller meetings at Tohoku University(Sendai, Japan) in March, and JINR (Dubna, Russia) in June, the workshop will continue to focus
on technical progress and planning for the ILC Technical Design Phase 1 (TDP-1), which will
culminate in mid-2010:••••

Progress on risk mitigating R&D, primarily the global high-gradient SCRF
programme; electron cloud suppression and ultra-small emittance generation in thedamping rings (CESR-TA, ATF, DAΦNE, etc.); ATF2 programme for demonstration of
the final focus optics and beam stabilisation.
Technical progress on engineering design work, specifically the SCRF linac(cryomodules) and development of ‘plug compatibility’ interface specifications. Global
31.5 MV/m cryomodule test (“Global S1”); development of world-wide infrastructureand SCRF test facilities; development of cost effective high-level RF power sources.
Machine Detector Interface (jointly with LCWS), including CFS for collider hall.
Consolidation of the Reference Design and Cost-Reduction studies; Main linac
CFS issues; further discussion on cost-driven alternative solutions (accelerator physicsdesign); further refinement/definition of the “minimal 200-500 GeV machine”. Sitedependency studies etc.

ILC08 will provide an opportunity to discuss these plans and share them with the larger
community.
The goals of the workshop are to:••••

Review current status of global ILC R&D and future plans, for both the baseline
configuration as well as the supported alternative designs;
Review and plan activities in and around Test Facilities (both existing and proposed);
Identify and prioritise critical R&D milestones for TDP-1 and beyond.
Promote and improve collaboration between groups working on ILC related R&D:
o To encourage a broader participation from active groups around the world;o To attract new researchers to the field;

oRefine proposed schedule, milestones, deliverables etc.

The workshop will follow the traditional collegiate structure with an open plenary session on thefirst day, followed by focused Working Groups (WG) in parallel sessions for the following twodays. A final summary and close-out plenary is scheduled for the last day. There will be plenary
discussions with the experimental community at strategic points during the workshop. Special
plenary sessions are foreseen for selected ‘young scientist’ presentations on key topics.
The detailed planning is expected to emerge over the next weeks, including joint sessions
betweenrelatedWGs.
