  1. VIPIX, pSuperB, (SuperB)Atlas/FTK M. Villa 04/11/2010

  2. VIPIX (2009-2011) • Sviluppo di sensori a pixel in integrazione verticale • High bandwidth • High rate (100 MHz/cm2) • Data push • Time identification 100 ns • Spatial resolution 12 um • Low budget material (<<1 Xo) • Caratterizzazione dei sensori su fascio • Trigger/DAQ • Memorie associative

  3. Prospetto architetture e sottomissioni Nomi Indicativi prossime sottomis-sioni Sensor Technology Readout architecture core version • Caratteristiche ed innovazioni introdotte nelle varie architetture: • 1 : AREO (Apsel family Read Out) • Apsel family read out • MP management logic • Parallel hit encoding • Sparsified column readout • 2 : SORTEX (SORTed EXtraction) • Time sorted hit extraction • horizontal parallelization (submatrices) • zone sparsification / output compression • I2C-like interface • 3: SQUARE (Sequenced QUery Advanced REadout) • No MP • Matrix TS query for time sequenced readout • Single column parallel sparsified readout (higher efficiency) • higher Time Resolution (more robust time sorting for short BC) Mixing interdetto

  7. Parallelamente…. DAQ: EDRO V2 • Born as a SLIM5 DAQ board • Recycling several boards: CMS muon trigger mezzanine, VME, CMS barrel sorter, S-Link & TTCrq • Used happily in beam tests • Reused in ATLAS as the LUCID DAQ board: • Bunch-by-bunch luminosity evaluation • Next use: • ZDC luminosity measurements • VIPIX DAQ • Vertical Slice “DO” board Can interface with an Associative Memory board for triggering purposes

  8. VIPIX DAQ duties Obbiettivo principale: Test beam settembre 2011 • Installare in gennaio-giugno tutta l’infrastruttura di beam test a Bologna: • 4 piani strip; 4 scintillatori; • 2 maps digitali (Apsel-like) + 1 analogico • 1-4 MAPS Perugine (RAPS) • 1 chip MIMOROMA3

  9. pSuperB: progetto pilota SuperB (R&D only) • Coinvolgimento di Bologna sulle tematiche del vertex detector: 80-90 % overlap con VIPIX • Chip di lettura • DAQ Elevate sinergie con il PRIN 2009 se verra’ approvato

  10. The SuperB Silicon Vertex Tracker Can use Babar SVT design for R>3cm Reduced beam energy asymmetry (7x4 GeV vs. 9x3.1 GeV) requires improved vertex resolution Layer0 very close to the IP (R~ 1.5 cm) with low material budget Background levels depends steeply on radius Layer0 needs to have fine granularity and radiation tolerance Bp pdecay mode, bg=0.28, beam pipe X/X0=0.42%, hit resolution =10 mm 20 cm 30 cm 40 cm Dt resolution (ps) MAPS (2 layers) Hybrid Pixels (single layer) • BaBar SVT • 5 Layers of double-sided Si strip sensor • Low-mass design. (Pt < 2.7 GeV) • Stand-alone tracking for slow particles. • 97% reconstruction efficiency • Resolution ~15μm at normal incidence old beam pipe new beam pipe Layer0 • Layer0 subject to large background and needs to be extremely thin: • > 5MHz/cm2, > 1MRad/yr, < 1 %X0

  11. R&D on strip/pixel options • Layer0 with striplets (technology mature but need some work): • Readout chip! (totally missing) • Module assembly with multilayer fanout (still uncovered !) • HDI/transition card electronics (partly covered by M.Citterio assuming similar to pixel option…not enough!) Hybrid pixel: • Prototype Front-end chip for hybrid pixel (32x128, 50 um pitch) tested • Results in fair agreement with simulation • Pixel sensor matrix produced and tested: good quality • FE chip + sensor matrix bump-bonding in june and test in lab in September CMOS MAPS: • Pixel readout architecture for next matrix (3D MAPS with 2 CMOS layers interconnected, ~Dec 2010) could work in data push and triggered mode • triggered readout reduces pixel module complexity (lower speed for links & less material for pixel bus)

  12. DAQ reading chain for L0-L5 HDI +Transition card+FEB+ROM DAQ chain independent on the chosen FE options Pi+Bo+Bg/Pv Milano Bologna Frascati, 28/09/10 12

  13. ATLAS/FTK • Progetto di tracking veloce in ATLAS basato sulle memorie associative • Si dovrebbe collocare tra il primo livello di trigger ed il secondo. E’ denominato L1.5 • “Feature extraction on L1 data” • Approvato in ATLAS in primavera • 2 Steps: • 2012 Vertical-slice test (parassitaggio su un quadrante) • 2013… Installazione su tutto ATLAS Siamo coinvolti Ci vogliono ma non abbiamo dato la disponibilita’ per ora

  14. FTK Event selection –trigger • LHC frequency 40 MHz • Events frequency on tape/disc 100 Hz • Selection is necessary • 3 trigger levels • first level (HW) • HLT (SW) • second level • Event Filter • FTK: HW processor to reconstruct charged tracks at LVL2 • Pt>1 GeV • Inside the whole ID • ~off-line quality Works in parallel with DAQ Can be added even after the data taking has began Francesco Crescioli

  15. Fast Tracker – Struttura interna • Ricieves hits from DAQ • ComunicateswithAssociative Memory boards • Sends hits &found roadsto the Fitter • 6 boards in parallel • Each DO handles 1-2 layers • Performs pattern recognition on Super Bins • Send back found roads to DO Struttura modulare Piu` processori possono lavorare in parallelo E` possibile iniziare con una versione prototipale e poi aggiungere EDRO in Vertical slice Roads and hits with high risolutionare composedand the Linear Fitis executed to select real tracks, stored in a buffer ready for the LVL2 CPUs Francesco Crescioli

  16. Guadagni con FTK • Miglior rapporto segnale/fondo; migliore capacità di discriminazione ai livelli di trigger bassi maggiore statistica finale Bs→μμ Results (CDF – ATLAS – ATLAS + FTK) • CDF with 780 pb-1of data 16/3/2006 • BR < 1.0x10-7 @95% CL • ATLAS (2006) • LVL1 2 muons Pt>6 GeV • 30 fb-1 21 B events 60 Backgr. • BR < 6.6x10-9 @90% CL • ATLAS + FTK • LVL1 singolo muone Pt>6 GeV • 30 fb-12ndm Pt>6 GeV 66 events (|η|<1 prototype) 178 events (|η|<2.5|) background LVL2 Rate for 2ndm Pt>3 GeV O(10Hz)

  17. Joint venture • Vertical Slice: • Pisa: AM board aggiornata • Americani: Interfaccia vs rivelatori a Pixel • Frascati: ricezione hit e clustering (EPMC) • Bologna: Data organizer (firmware/software) Elevate sinergie con il PRIN 2009 se verra’ approvato

  18. Mezzanina ricezione hits • Compatibilita’ EDRO; • Usabile anche per SuperB • Progetto finito; produzione 10 pezzi a breve

  19. Riassumendo • Impegni certi: • VIPIX: sviluppo architetture RO, layout 2 chips • VIPIX: test beam 2011 – Software/firmware • pSuperB/SuperB: sovrapposizione VIPIX • ATLAS/FTK: commitment fino alla vertical slice (2012) • ATLAS/FTK: sviluppo software e firmware (Ing. Ele.) • Impegni possibili/da decidere: • ATLAS/FTK oltre il test del 2012 • SuperB (se approvato) quante forze? • Oltre il 2011: continuazione di VIPIX? • Impegni probabili: Prin2009/Vipix+FTK-like • Impegni chiusi: Prin2007
