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

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

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

KEKB Beam distributions SuperB Beam distributions 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 KEKB SuperB current 1.7 A 2.3 A betay 6 mm 0.3 mm betax 300 mm 20 mm sigmax ~80mm ~6mm sigma y ~3mm 0,035mm Sigma z L 1.7 1034 1 1036 SuperB Beam distributions at the IP

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

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.

First Meeting of the SuperB Mini-MAC LNF, Frascati, Italy July 16-17, 2008 Comments from the Closeout

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)

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.

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

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
