  1. HFT Project Overview CD0 Review H.G. Ritter LBNL

  2. Compelling science • Elementary charm cross-sections • Parton energy loss • Charm flow and thermalization CD0 Review

  3. Justification • In the first part we have shown • Compelling science • Proposed detector can do necessary measurements • In the second part we will show • Properties of detector • How we build it • We have the team and the organization to build it CD0 Review

  4. Major Milestones • List all the previous reviews CD0 Review

  5. Definition STAR Tracking Upgrade to identify D and B mesons through measurement of the displaced vertex CD0 Review

  6. Optimal technology • New pixel technology • Resolution • Low material budget • Proven strip technology • Experience • Cost effective CD0 Review

  7. PIXEL • 2 layers of 30x30 m pixels at 2.5 and 8 cm radius • Very thin material budget to limit multiple scattering • Data reduction and formatting on chip • Rapid insertion and removal • Precision positioning • Air cooling CD0 Review

  8. PIXEL CD0 Review

  9. Patch for run 11 CD0 Review

  10. IST • One layer of single sided strips (pads) at a radius of 14 cm • Conventional and proven technology • MIT expertise CD0 Review

  11. IST CD0 Review

  12. SSD • Existing detector • Needs upgrade and TLC CD0 Review

  13. Collaboration • BNL:C. Chasman, D. Beavis, R. Debbe, J.H. Lee, M.J. Levine, F. Videbaek, Z. Xu • UCLA:R. Cendejas, H. Huang, S. Sakai, C. Whitten • Kent State:J. Joseph, D. Keane, S. Margetis, V. Rykov, W.M. Zhang • Prague:M. Bystersky, J. Kapitan, V. Kushpil, M. Sumbera • Strasbourg:J. Baudot, C. Hu-Guo, A. Shabetai, M. Szelezniak, M. Winter • MIT:J. Kelsey, R. Milner, M.

  15. HFT Technical Committee Ritter - Project Manager Singh - Deputy Project Manager Morgan - Budget Videbaek - Integration Wieman - Pixel Anderssen - Pixel, Integration Surrow - IST Kelsey - IST, Integration Thomas - SSD Liaison Margetis - Software Hallman - STAR Majka - STAR Weekly meetings, change control CD0 Review

  16. Risk Management • APS Sensor depending on Strasbourg pace of development • Push for early prototype, get involved in testing and design • Kinematic mount and low weight ladder challenging • Solve problem in the R+D phase • SSD is essential • Get involved in upgrade and running of SSD, design some redundancy into IST • HFT might become operational late • Build patch to test design and get early measurement CD0 Review

  17. Cost CD0 Review

  18. Proposed Schedule CD0 Review

  19. Summary • Compelling Science • A detector • That can deliver the science • Has the right mix of new and proven technology • A team and an organization • That can build the detector • That will extract the science in a timely fashion CD0 Review
