9. WWSWWS WWS Report, ILCSC, Dubna, 6/4/089 Funding Challenges in US and UK UK –recovery for detector effort more difficult than for machine –go generic - connect to CLIC work US –Uncertainty in DOE/NSF response to P5 HEPAP approved P5 recommendation of more funding for detector R&D both DOE and NSF are considering the report –Generic aspects of detector R&D important –Engineering support for LoIs currently restricted –LoI process requires strong lab (Fermilab/SLAC) participation - uncertain, difficult in current climate

10. WWSWWS WWS Report, ILCSC, Dubna, 6/4/0810 P5 Report The panel recommends for the near future a broad accelerator and detector R&D program for lepton colliders that includes continued R&D on ILC at roughly the proposed FY2009 level in support of the international effort. This will ensure a significant role for the US even if the ILC is built overseas. The panel also recommends R&D for alternative accelerator technologies, to permit an informed choice when the lepton collider energy is established. The panel also recommends an R&D program for detector technologies to support a major US role in preparing for physics at a lepton collider. Approved by HEPAP, May 29, 2008

11. WWSWWS WWS Report, ILCSC, Dubna, 6/4/0811 Role of WWS in RD Era Many WWS activities are being transferred to RD –eg. Roadmap planning, MDI studies, Detector R&D coordination, etc. –WWS co-chairs are serving as initial RD regional contacts WWS is the community (like user group) WWS should –Cooperate with RD –Organize workshops WWS is evolving into new role

12. WWSWWS WWS Report, ILCSC, Dubna, 6/4/0812 Conclusion LoI groups are hard at work developing integrated detector designs in support of the GDE machine design effort –Demonstrate realistic detector performance –Address machine detector interface issues Uncertainty regarding long term impact of funding cuts in UK and US
