  1. superB story • The INFN roadmap 2006 included a flavour factory in a general framework of development of the Frascati National Labs area • From the beginning the project was seen as an international collaboration with a INFN as the host Institution

  2. SuperB • Soon after a CDR was commissioned • CDR was ready by may 2007 • A review committee chaired by Dainton was formed and ended his work last april • Short report was issued in may 2008

  3. Basic facts • The machine makes use of the crab waist leading to high luminosities at low currents • The goal is to reach the luminosity threshold of 10^36 , 100 times current factories, where new physics could be detected or studied • The new scheme has been tested at the Frascati National Labs

  4. The beam diet Beams are focused in the vertical plane 100 times more than in the present factories, thanks to: - small emittances - small beta functions - large crossing angle - Crab waist Tune shifts and the longitudinal overlap greatly reduced KEKB Beam distributions at the IP SuperB Beam distributions at the IP

  5. The current site proposal: Tor Vergata University campus • Strong synergy with a nanometer class FEL project already approved in the area

  6. Report from the International Review Committee • membership: Hiroaki Aihara, John Dainton (chair), Young Kee Kim, Jacques Lefrancois, Antonio • Masiero, Steve Myers, Abe Seiden • Conclusions • We recommend strongly that work towards the realisation of a SuperB, taken to be an asymmetric e+e- collider with luminosity at least 1036 cm-2 s-1, continues. • The SuperB concept is at an important stage. The significance of the physics programme at such a machine continues to be developed, increasing in both scope and importance. It motivates an even more concerted effort to meet many technical challenges, in particular concerned with the design of storage rings which meet the physics specification. • So far there has been no showstoppers; rather there has emerged a number of innovative and noteworthy developments at the cutting-edge of contemporary technique in accelerator physics and detector technology. There still remains the possibility of insurmountable technical challenges, in particular in establishing the physics of machine performance which, in some aspects, address fundamental issues of accelerator physics. Beginning as soon as possible, these challenges must be addressed if progress is to continue with the aim of realising SuperB on the proposed time schedule. To this end, it is now both timely and highly appropriate that a machine Advisory Committee be established to oversee progress in the many critical issues faced in the design of the SuperB asymmetric collider.

  7. First Meeting of the SuperB Mini-MACLNF, Frascati, ItalyJuly 16-17, 2008Comments from the Closeout

  8. Mini-MAC Committee • Klaus Balewski (DESY) • John Corlett (LBNL) • Jonathan Dorfan (SLAC, Chair) • Tom Himel (SLAC/on sabbatical at DESY) • Claudio Pellegrini (UCLA) • Daniel Schulte (CERN) • Ferdi Willeke (BNL, by phone) • Andy Wolski (Liverpool) • Frank Zimmermann (CERN) (Stuart Henderson was unable to attend)

  9. Mini-MAC Charge (a) to perform an initial assessment of the current design to review its viability to achieve the design operating parameters. This initial assessment would provide clear guidance regarding perceived weaknesses in the design and would further identify those areas in need of more detailed design work and focused R&D. The goal would be to complete this initial review within the next three months (As of June 2008). (b) to provide initial guidance on potential site-specific issues for Super B at the Tor Vergata site. (c) to provide ongoing, periodic assessments of the design as it matures over the subsequent nine months.

  10. General Comments • Very exciting project -- Committee is exhilarated by the challenge • Physics requirement of 10**36 cm-2 sec-1 or 75 ab-1/5yr is very demanding • Requirement of polarization potentially adds complexity • Imaginative and ambitious design -- Committee endorses the design approach. Design offers flexibility to either raise the luminosity or compensate for surprises • Excellent work by a relatively small group, many of whom have full-time “day jobs” • Seeman’s summary – “areas for further concentration”: Committee agrees these cover most of the essential tasks needed before the design can be fully vetted at the performance requirements

  11. Recommendations Committee considers the SINGLE MOST ESSENTIAL ingredient for moving forward is the formation of a sanctioned management structure which formally incorporates a dedicated machine design team. The team members must have the strong support of their home institutions to work on the design. The team needs a designated leader, who is as close to full time as is possible The project is in need of a formal baseline which is managed with change control tools. This cannot be accomplished successfully without the management structure

  13. New mini Mac report soon

  14. Further elements • The project may develop accelerators tools relevant to major accelerators • LHC ( interaction region) • ILC/CLIC (low emittance, damping rings) • Complementarity with LHC new physics reach

  15. About the project’s size • A Regional project • Cern strategy session • ECFA assessment • A mini-Global project • Likely only one last generation B factory for the world community • ICFA assessment • The international governance likely extends outside Europe

  16. Formal steps • Last December the INFN board of directors approuved the formal engagement for the TDR phase • Last friday the INFN restricted board approuved the framework agreement with Lazio region to sustain the TDR phase

  17. items • Logistic infrastructures at LNF • Accelerator complex civil engineering design • Senior physicists exchange program • Young phisicists, engineers, technician training program • A dedicated computing facility for ab initio calculation of relevant matrix elements for B physics • R&D program for detectors • A Technology Transfer program spinning around the project • An outreach project

  18. timescales • The Mou for the Design Team …. now, under the auspicies of Cern strategy session secretariat • Bilateral MOUs within a general framework with an established tasks distribution • Discussion starts to identify the possible form of an international consortium • Construction negotiations after the Italian Government approval and an endorsement of the european council session starting by 2009
