This workshop aims to discuss the status and goals of the SuperBFRASCATI project, including the machine design and physics case. Topics covered include beam polarization, machine simulations, layout options, and cost considerations. Join us to contribute to the decision-making process and help shape the future of this project!

Closeout Remarks 2nd Workshop on SuperBFRASCATI 16- 18 March 2006 Marcello A. GiorgiUniversità di Pisa and INFN Pisa Marcello A Giorgi
OUTLINE From my opening talk • More on physics case at Super Flavour Factory • Status of the art • Goals of the workshop Marcello A Giorgi
From Physics presentation M.Ciuchini Marcello A Giorgi

ON THE MACHINE Pantaleo has presented the results of simulations on various possible designs. John has presented a solution possibly making use of he present PEPII setup and components (including the tunnel) Marcello A Giorgi
Machine design under discussion • USE of ILC DR + ILC FF Requires virtually no R&D • Uses all the work done for ILC • Ring and ff layouts virtually done, 3km circunference rings • 100% Synergy with ILC • IR extremely simplified 80-100 m straight line • Beam stay clear about 30sigmas with 1cm radius beam pipe • Currents around 1.5Amps • Background better than PEP and KEKB • Possibly to operate at the tau with L=10^35 • Polarization of one beam considered • UNDER STUDY the possibility to run down to the phi with lumi<10^34 • Total cost about half of the ILC e+ DRs (2 e+ 6km rings in ILC) • Power around 40MW, still to be further optimized (goal 25MW) • Possible to reuse PEP RF system, power supplies, Vacuum pumps, etc., further reducing the overall cost • Needs the standard injector system, probably a C-band 7GeV linac like in KEKB upgrade (already designed) Marcello A Giorgi

2 most popular solutions John and Pantaleo designs seems so far the closest to a possible baseline choice. We need from now and next workshop a lot and well coordinated work to arrive to a satisfactory decision before the summer. Marcello A Giorgi
First meeting of the steering Committee Yesterday, we will meet again tomorrow morning at 9.0 Next workshop on june 14,15,16 (To be confirmed) at SLAC. Decision on the baseline design for the machine. Start writing the first conceptual document. Marcello A Giorgi
Toward the CDR A final workshop is needed in October (beginning of) to be able to write a reasonable CDR before the end of the current year. A theory workshop will be held contiguous to ours and devoted to the preparation of the physics chapter of the CDR Marcello A Giorgi
