30 marzo 2009F.Forti SuperB Status CSN18 Comments on reviews Link to meetings and reports: B/reviews Dainton committee  Mini MAC 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 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 Committee sees no glaring showstoppers wrt achieving the design performance. However, in several key areas, more work is needed before the design can be blessed

30 marzo 2009F.Forti SuperB Status CSN19 ECFA report *We consider that flavour physics should be seen as an important part of the European research programme of elementary particle physics, complementary to physics provided by the energy frontier experiments. For the coming ~5 years, LHCb will do this job in the b and c quark sectors. To follow-up this progress, collecting 50 ab−1 or more at Υ(4S) energy with e+e− storage rings by the end of the next decade would be a significant milestone, if this can be realised at a moderate cost. *The INFN Super Flavour Factory project team proposes a novel scheme […]. This idea of obtaining a high luminosity with tiny beam spots at the collision point based on very small emittance beams and crab waist collisions could revolutionize the design of the future colliders. Therefore, westrongly support the R&D effort to see if such a machine can really be built. *The current tests at DAFNE are promising and we would like to congratulate the team for this impressive achievement. However, a substantial amount of work is still required for producing a Technical Design Report, […] *Given the complexity of the project, we feel that a clear plan containing realistic technical milestones and resource requirements together with a strategy how to obtain them is needed as a necessary condition for an approval of the project. *Such a plan should aim at obtaining an integrated luminosity of significantly more than 50 ab−1 by not much later than the end of the next decade. Given the very ambitious time scale, a clear decision taking process must be established soon.

Manpower (and chip production schedule!) is compatible with the following schedule of activities: 1.Hybrid Pixels: –Sept 2009 produce small prototype Front-End chip for hybrid pixel (50x50 um pitch, same readout architecture data push developed for MAPS chip, reoptimize analog cell) –Sept 2009 produce pixel sensors (ITC, IRST) –Test with beam Sept 2010 pixel sensor bump bonded to the FE chip. 2.Pixel module integration studies continue (similar characteristics for MAPS/Hybrid pixel modules) to end up with a solid module design for TDR. 3.Continue R&D on MAPS: –Large Matrix (APSEL5D~40 mm2 active area) in production in ~Jan 2010, –Radiation damage studies –Develop Pixel module components –Testbeam on APSEL5D in Sept. 2010, very likely as a single chip (probably no time for MAPS module integration). –Later testbeam (post TDR with MAPS module) At the time of the TDR report on progress on MAPS as possible solution for performance improvements.

30 marzo 2009F.Forti SuperB Status CSN170 Verbale F.Forti presenta gli update sulle attività di SuperB da Settembre I test di macchina previsti su DaFne del concetto di crab-waist si sono conclusi in modo soddisfacente, e sostanzialmente si possono considerare concluse le verifiche sulla fattibilità dell’acceleratore. Nel corso del 2008 il progetto SuperB ha ricevuto l’approvazione del comitato di review internazionale (Dainton committee), del Mini MAC(Dorfan committee) e di ECFA. A dicembre 2008 il direttivo INFN ha approvato il progetto speciale SuperB TDR, per la preparazione del Technical Design Report, ed è in corso di finalizzazione un accordo con la regione Lazio per il finanziamento delle attività TDR di SuperB, previsto essere 5M€/anno per tre anni. Tale finanziamento potrà co-finanziare, fra le altre cose, attività di R&D sul rivelatore e contratti finalizzati alle attività per il TDR. Il progetto SuperB si è dotato di una struttura organizzativa, che comprende un gruppo di management (Direttore e tre deputies) e quattro strutture principali: Acceleratore, Rivelatore, Computing, Sito e infrastrutture. Si prevedono due fasi per la preparazione dei prossimi report: –a fine 2009 i documenti per l’approvazione da parte del governo: una Technical Description dell’acceleratore, un Accelerator site study, un design report sul rivelatore; –a fine 2010 i documenti necessari per una review tecnica completa e il baselining di costi e schedule: Technical Design Report/Engineering Design Report per acceleratore, sito, rivelatore. Il TDR del computing potrebbe arrivare successivamente. Forti procede a presentare i dettagli delle attività del gruppo SuperB per la preparazione del Technical Design Report, disponibili nella presentazione. Vengono individuati gli elementi per cui si può ottenere il cofinanziamento della regione Lazio, al momento in cui i finanziamenti diventeranno disponibili. Tali elementi sono: SVT: Cofinanziamento prototipo modulo Layer 0 EMC: Cofinanziamento del prototipo di calorimetro IFR: Cofinanziamente del prototipo IFR Elettronica: Acquisto strumentazione di test L’entità dei finanziamenti è ancora da definire. Le richieste finanziare consistono nello sblocco dei SJ sul materiale inventariabile, alcune integrazioni di consumo, e l’integrazione delle missioni per poter svolgere le attività previste durante il 2009
