  1. Electron-Ion Collider and the NSACLong Range Plan Robert Tribble December 7, 2007 Texas A&M University

  2. LRP Decisions • Four Principle Recommendations for facilities

  3. LRP Decisions • Four Facility Recommendations • Additional recommendation on EIC

  4. Further Into the Future An Electron-Ion Collider (EIC) with polarized beams has been embraced by the U.S. nuclear science community as embodying the vision for reaching the next QCD frontier. EIC would provide unique capabilities for the study of QCD well beyond those available at existing facilities worldwide and complementary to those planned for the next generation of accelerators in Europe and Asia. In support of this new direction: • We recommend the allocation of resources to develop accelerator and detector technology necessary to lay the foundation for a polarized Electron Ion Collider. The EIC would explore the new QCD frontier of strong color fields in nuclei and precisely image the gluons in the proton.

  5. What Are the Issues? • Develop the Science Case • This workshop is a step in that direction • Science needs to have broad impact for large project • Must be important for rest of NP at a minimum • May need to be ‘transformational’ with high price tag

  6. What Are the Issues? • Develop the Science Case • Choose Site? • Can this be done without contention? • Will the science dictate a solution? • MSU vs ANL did not help RIA

  7. What Are the Issues? • Develop the Science Case • Choose Site? • Develop Sound Cost Basis • A roughly $120 M upgrade at JLab (from 2002 LRP) has grown to over $300 M (RIA similar) • This has led to much grumbling in other segments of NP – not helpful for selling a new project

  8. What Are the Issues? • Develop the Science Case • Choose Site? • Develop Sound Cost Basis • What is cost versus science tradeoff? • Today above ~$600 M is difficult • Around ~$1 B must be ‘transformational’ • When does it become International?

  9. What Are the Issues • Develop the Science Case • Choose Site? • Develop Sound Cost Basis • What is cost versus science tradeoff? • Secure the NP doubling budget

  10. DOE NP Budget Profile

  11. What Are the Issues • Develop the Science Case • Choose Site? • Develop Sound Cost Basis • What is cost versus science tradeoff • Secure the NP doubling budget • Next LRP very important (i.e. critical?) for EIC

  12. A New Long Range Plan forU.S. Nuclear Science Many Pitfalls To Avoid!
