15 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. An example: Alice hybrid pixel module ~ 1% X0 Possible material reduction with the latest technology improvements Viable option, although marginal PRE SHAPER DISC LATCH 30 giugno 2009 F.Forti - SuperB Status

18 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 CSN 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

19 Utilizzo assegnazione 2009 MAPS-Pisa
L’assegnazione a Pisa 80+5 kE per MAPS chip+testboard (rimandata all’inizio del 2010) verra’ invece utilizzata nel 2009 per pixel ibridi e meccanica per Layer0: Chip FE pixel ibridi (32x128 pixels, ST130nm) Sett. 2009: 40 kE Produzione  sensori per pixel ibridi  FBK-IRST Sett. 2009: 15 kE Chip carriers +Testboard pixel ibridi per lab test: 5 kE Materiale e lavorazioni ulteriori prototipi mecc: 22 kE Evoluzione supporti moduli a microcanali Layer 0 con ulteriore riduzione materiale: da 0.3% a 0.2% X0 (15 kE) Opzioni supporto pixel ibridi per layer0+layer1 (3 kE) End-flange Layer0 (4 kE) 30 giugno 2009 F.Forti - SuperB Status

20 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

21 DCH –ongoing work Studies on system design
Fast simulation studies on subsystems boundaries for design optimization – LNF Detailed simulation of gas mixtures and cell geometry with Magboltz/Garfield/Heed – Carleton Comparison and Preliminary overall design for drift chamber (e.g. endplate considerations, square vs. hexagonal cells, all-stereo, etc) – TRIUMF/UBC Laboratory work at LNF Gas infrastructure completely redone External tracker recomissioned Test tubes inserted and working First cosmic ray data collected (80%He-20%isob.) Analysis ongoing Laboratory work at UVic experimental validation of Magboltz/Garfield/Heed description of candidate gas properties (gain, drift velocity, diffusion, clustering) Gruppi canadesi finanziati per il 2009/2010 30 giugno 2009 F.Forti - SuperB Status

22 Particle Identification
Hadronic PID system essential for P(p,K)>0.7GeV/c (use dE/dx for p<0.7GeV/c) Baseline is to reuse BaBar DIRC barrel-only design Excellent performance to 4GeV/c Robust operation Elegant mechanical support Photon detectors outside field region Radiation hard fused silica radiators Photon detector replacement Baseline: Use pixelated fast PMTs with a smaller SOB to improve background performance by x with identical PID performance 30 giugno 2009 F.Forti - SuperB Status

23 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. Can 10ps be achieved ? 30 giugno 2009 F.Forti - SuperB Status

24 The electromagnetic calorimeter
BaBar Barrel 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. IR shielding design is crucial Endcaps Best possible hermiticity important for key physics measurements New forward endcap backward endcap is an option 30 giugno 2009 F.Forti - SuperB Status 24

25 Forward and backward EMC
Forward endcap BaBar CsI(Tl) endcap inadequate for higher rates and radiation dose of SuperB Need finer granularity Faster crystals and readout electronics comparable total X0 Option 1: LYSO crystals frees 10cm for a forw. PID system radiation hard, fast, small Moliere radius, good light yield expensive (~40$/cc) at the moment Option 2: retain 3 outer rings of CsI(Tl), LYSO the others less expensive no space for forw. PID system Backward endcap (option) Pb plates and scintillating tiles with fiber readout to SiPMs 30 giugno 2009 F.Forti - SuperB Status

28 Strategia per prototipo IFR
A MARZO 2009: Necessità di poter operare anche in un ambiente ‘ostile’ come flusso di neutroni Utilizzo di fibre chiare per allontanarsi dalla zona ‘calda’ Aumento numero di fibre scintillanti per recuperare la luce persa Aumento dimensione del fotorivelatore per leggere tutte le fibre di una slab di scintillatore TEST EFFETTUATI: Test sui SiPM confermano il danno da radiazione a 109 n/cm2 Aumento delle fibre scintillanti porta solo miglioramenti marginali Necessità schermaggio locale dei fotorivelatori 30 giugno 2009 F.Forti - SuperB Status 28

29 1 vs 2 vs 3 kuraray fibers at the close end (CLOSE end: ~0
1 vs 2 vs 3 kuraray fibers at the close end (CLOSE end: ~0.3m from scintillator) 1 fiber R2/1 = 1.46 R3/1 = 1.65 ADC ch With 3 fibers we gain only 13% more signal wrt 2 fiber case 2 fibers 3 fibers 30 giugno 2009 F.Forti - SuperB Status

30 If preliminary results will be confirmed SiPM can be damaged with a
dose of 109 n/cm2 Need for accelerator background simulations + study on neutron shielding 30 giugno 2009 F.Forti - SuperB Status

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

32 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

33 Detector decisions Major “Global Geometry” decisions
