Silicon Vertex Tracker The Babar SVT technology is adequate for R > 3cm: use design similar to Babar SVT Layer0 is subject to large backround and needs to be extremely thin: More than 5MHz/cm2, 1MRad/yr, < 0.5%X0 Striplets option: mature technology, not so robust against background. Marginal with background rate higher than ~ 5 MHz/cm2 Moderate R&D needed on module interconnection/mechanics/FE chip (FSSR2) CMOS MAPS option new & challenging technology: can provide the required thickness existing devices are too slow Extensive R&D ongoing on 3-well devices 50x50um2 Hybrid Pixel Option: tends to be too thick.

Dopo incontro Marzo 2009 in CSN1 Giudicato ragionevole il nuovo piano di R&D proposto per TDR Layer0 con cofinanziamento CSN1(150kE) -Prin (40 kE) - Regione Lazio (100kE ancora acquisire) Lavoriamo con questa ipotesi Parte dell’assegnazione di CSN1 2009 per Layer0, destinata in origine all’attivita’ MAPS-Pisa (85kE), che e’ rimandata all’inizio del 2010, viene utilizzata per pixel ibridi e su meccanica per Layer0 (60+22kE). Il resto dell’assegnazione del 2009 nelle varie sedi viene usata sugli items Layer0 effettivamente finanziati. Inseriamo nei preventivi INFN 2010: items Layer0 previsti essere coperti da cofinanziamento Regione Lazio nuovi items per altre attivita’ Layer0 altre attivita’ SVT non legate ad R&D per Layer0. 30 giugno 2009 F.Forti - SuperB Status

The drift chamber Build on BABAR drift chamber concept: no major R&D effort needed, but: Lighter structure, all in Carbon Fiber (CF) Preliminary studies show that dome-shaped CF end-plates with X0~2% seem achievable (compare 13-26% in BaBar DCH) Design faster&lighter electronics (taking into account detectors options to be possibly installed behind backward end-plates) To control expected increase in occupancy: studying faster gas mixtures considering smaller cells alternative solutions being explored tapered shape of end-plates LNF Canada: Carleton, McGill, UVic, UBC, TRIUMF 30 giugno 2009 F.Forti - SuperB Status 20

Forw/Back PID option Extending PID coverage to the forward and backward regions has been considered Possibly useful, although the physics case needs to be established quantitatively Serious interference with other systems Material in front of the EMC Needs space cause displacement of front face of EMC Technologies Aerogel-based focusing RICH Working device Requires significant space (15 cm) and thickness (about 28%X0) Time of flight Need about 10ps resolution to be competitive with focusing RICH 15-20ps already achieved.

The electromagnetic calorimeter BaBar Barrel 5760 CsI(Tl) Crystals Essential detector to measure energy and direction of g and e, discriminate between e and p, and detect neutral hadrons Barrel BaBar barrel crystals not suffering signs of radiation damage. They’re sufficiently fast and radiation hard for SuperB needs They can be reused. (Would have been) most expensive detector component Background dominated by radiative Bhabhas.

ETD architecture proposal 30 giugno 2009 F.Forti - SuperB Status

ETD Status Main issue is the high speed links: Readout module Difficult to get fixed link latency and jitter There already is a solution for a fully FPGA-based link => OK for the off-detector links Jitter measurements are at the level of 20ps rms. R&D work has to start on the detector side to find a solution for the radiation area Alberto Aloisio (INFN Napoli) has been given the charge of managing these activities. Readout module Based on the experience from AGATA experiment, a tentative proposal for the design of the ROM exists Padova and Bologna are interested in this design. ECS link to the detector The SPECS bus, designed for LHCb, has been presented. Interest in LAL LAL could also take care of the FTCS system. Activities linked to L1 trigger are still uncovered. 30 giugno 2009 F.Forti - SuperB Status
