12 LAV stations mounted along 120 meter decay region 6 meters apart 4 different types: –160, 240 blocks; 5 layers in vacuum –240 blocks; 4 layers in vacuum –256 blocks; 4 layers in air Angular coverage 8-50 mrad Inefficiency < from few hundred MeV to 35 GeV 2500 lead glass blocks (OPAL barrel calorimeter) Efficiency measurements with electron beams in 2007: 1-  <10 -4 for 200 MeV<E<500 MeV A1-A11 Vacuum LAV – Large Angle Photon Vetoes

13 A3 shipped at CERN beginning of December 2010, some problems during the transport (see later) A4 completed tested and ready to be shipped at cern, we are currently revisiting the transportation procedure A5 arrived at LNF February 18, actually 3 out of 5 layers are mounted and tested, we foresee to complete it by mid April (2 months delay respect to the schedule)

14 A6-A8, A11 Bidding procedure closed adjudicated by Fantini factory, all drawings have been revisited and the material has been procured. A6 is actually scheduled and will be shipped to LNF end of May. We foresee to build and test A6-A8 during 2011 A6-A8 5 layers ∅ 259 cm A11 4 layers ∅ 299 cm

15 Recall: A9, A10 have same dimensions as A11, but are made of stainless steel A12 has open geometry—design is totally different A9-A10 drawings will be revised in the next months and we will start the bidding procedure, the idea is to start vessels construction by the end of 2011 A6-A8 5 layers ∅ 259 cm A11 4 layers ∅ 299 cm

16 A3: Due to bad weather conditions (M.Blanc tunnel was closed) the transport took 3 days. Even if all precautions where taken, we insulated the vessel by means of fiberglass cover, the temperature in the vessel reached 5 degrees after 2 days in the snow. 10 blocks were broken during transport! Fractures are most likely from thermal stress Likely from re-heating from ~4 ∘ to 15.5 ∘ at ECN3 (cooling was much slower) 9 of 10 blocks on layers most exposed to ambient temperature We have already started A3 repair work in ECN3 6 of 10 blocks repaired Unfortunately A2 experienced a significant temperature gradient: A2 was shipped to CERN end of JULY 1) All the blocks were checked at CERN before the test beam and they were ok 2) The idea was to store all the LAVs in building 185. We were ensured that 185 was air conditioned during summer and heated during winter (including shutdown). A2 was stored in building 185 at the end of August. 4) We went to inspect A2 in February and found 22 blocks broken !! 5) The heating in 185 was switched off without notice during the winter shutdown and never restarted 6) From now on all the LAVs will be stored in ECN3 and an appropriate temperature monitor has been implemented

NA62 Pisa TDAQ Il gruppo ha subito un pesante ridimensionamento: In un anno: –3 FTE dedicati di grande esperienza Tecnologi (a tempo parziale) << richieste Richiesto art. 23, ottenuto 2222, assegnato, rinuncia, nuova assegnazione [nessun effetto su manpower netto] Praticamente nessun supporto da altri gruppi di NA62 Attivita’ fondamentali per la collaborazione: - Sistema integrato di trigger e readout basato su TDC (per 80% dei rivelatori INFN e non) - Upgrade schede madri comuni (per quanto sopra e anche per altri sistemi) M. Sozzi responsabile TDAQ NA62 Fine sviluppo 2011 Produzione e test su fascio 2012 Installazione e commissioning 2013

Pisa TDAQ: Scheda TDC Scheda figlia ( ps) per la maggior parte dei sistemi di readout di NA62 R&D per utilizzo in readout di EEE per telescopi raggi cosmici

Pisa TDAQ: Scheda TDC Storia: - Progetto non portato a termine dal progettista (G. Magazzu) - Parzialmente modificato da ass. ric. “in prestito” (A. Burato) - A. Burato lascia INFN con 1 giorno di preavviso (5/2011) Stato attuale: - Prototipi versione finale a giorni (S. Galeotti), cavi OK - Esiste versione di firmware “funzionante” (sotto test, non completa) ma completamente “as is” - “Richieste minime” firmware (1/2009) non completate - Sistema di test “automatizzato” in preparazione - Hardware per test produzione da disegnare e costruire Futuro: - Produzione ~14 schede tra 1 mese - Distribuzione nella collaborazione per test - Lancio produzione finale (~100) entro fine 2011

Pisa TDAQ – TEL62 Scheda madre per la maggior parte dei sistemi di trigger e readout di NA62 16 layer, impedenza controllata

Storia: - Sostanziale ridisegno della scheda TELL1 di LHCb - Scheda complessa - Disegno completato a Pisa (F. Spinella, E. Pedreschi) - Layout al CERN (dic 2010-feb 2011) Stato attuale: - 1 prototipo (2 PCB) a Pisa da - Test elettrici OK - Compatibilita’ schede figlie OK - Inizio sviluppo firmware - Per ora nessun supporto da altri gruppi Futuro: - Tutti i test funzionali - Secondo prototipo (modifiche minime per ora) - Produzione ~10 schede entro Produzione (~100) 2012, coinvolgimento Roma TV Pisa TDAQ – TEL62

Processore L0 (resp. INFN): ancora poco progresso - Pisa non coinvolta in implementazione, come richiesto (ma disegno concettuale) - Studi su implementazione in PC iniziati (FE/CERN) - Responsabilita’ software: Ferrara - Responsabilita’ hardware: non ancora identificata - Milestone: demonstrator fine 2011 Rete (per readout/trigger/L0): esiste expertise a Pisa (non INFN): identificare modo per poterla sfruttare R&D: studio implementazione trigger HW con GPU - Ongoing - Ricostruzione online anelli RICH - Studio di reiezione fondo in camere straw a L1 Simulazione: ripreso lavoro Monte Carlo a Pisa (obiettivo: rate di L1/L2, decadimenti rari) Pisa TDAQ: Altro

Pisa TDAQ – 2012 Il problema di manpower sta condizionando il mantenimento degli impegni INFN. Per Pisa TDAQ: - Completamento firmware TDCB - Produzione e test (test bench) TDCB - Firmware TEL62 - Produzione TEL62 Produzioni fine 2011/2012, ma acquisto componenti critici): O(200KE) finanziamento CORE “Dry run” per TDAQ a primavera 2012 (pesante coinvolgimento di Pisa) Pisa e’ il gruppo di riferimento per il TDAQ. E’ indispensabile maggiore manpower e supporto elettronico qualificato, per il completamento dell’hardware, lo sviluppo del firmware e il test Con il manpower attuale la schedule subira’ ritardi

Richieste 2012 TDAQ: Secondo prototipo TEL62: 10 KE (sub judice) Sistema di test per TDCB: 10 KE Materiale laboratorio: 8 KE (Sonda diff. + PC sviluppo firmware) CORE 2012: 450 KE previsto per TDAQ-I (Produzioni) di cui 150KE Pisa Possibile rimodulazione sul 2013 Dry run (~1 mese): 4 FTE Manpower necessario: F. Spinella, E. Pedreschi (TEL62 ma anche TDCB) +1 Fisico/tecnologo per firmware +0.3 FTE per gestione produzione +Coinvolgimento esperto reti LAV: CORE 2012: 80 KE (Costruzioni), metabolismo, trasporti, installazione Manpower necessario: Turni a LNF LAV + TDAQ: Technical run (~3 mesi): 3 FTE
