  1. GRUPPO III CDS 8 Luglio 2014 Richieste per ilbilancio 2015

  2. ComposizionegruppoIII di Cagliari • Personetotali (escl. Tecnici): 15 Staff (5) • FTE: 12.1 (escl. DIS) • PhD: 1 • Assegni 3 • Contratti 1 • Incarichi di responsabilita’ in ALICE: 4

  3. Intro muon arm e ZDC (CC) • RislutatiAnalisi (Alessandro) • Stato ITS Upgrade (Gianluca) • StatoCalcolo (Alberto) • Richiestefinanziarie(CC)

  4. ALICE – Spettrometro per Muoni • Attivita’ in corsoduranteil long shutdown 1 • Manutenzionedeirivelatori in caverna (saldature, gas leakage test) • Scariche sotto fasciosualcunirivelatori ->planning riparazione. • Upgrade del Detector Control System • Impegnoofficina e laboratori • Attivita’ prevista per il 2015

  5. MCH UpgradeElectronics and readout scheme • New FEE based on SAMPA chip (1.1 M channels, ~20k boards of 64 ch) • New e-link data buses (external to detectors for slats, new PCB for quadrants) • GBT concentrator card (40 x 80 Mb/s inputs, 3.3 Gb/s fiber output): ~500 cards • Common Readout Unit (CRU) interfaced to the DAQ: ~500 inputs, ~20 boards

  6. The SAMPA chip • « All-in-one » (analog & digital) 32 ch chip for MCH and TPC • Based on SALTRO architecture, designed in TSMC 130 nm • Analog (pre-amplifier + shaper), continuous sampling (10/20 MHz), 10 bits ADC • Digital processing (DSP): baseline correction, zero suppression, multi-event buffers, … • Continuous or triggered readout • Sampling and readout running in parallel • Specifications done (MCH & TPC) • Planning • First prototype (few channels) submitted • test bench design in progress • 32 ch prototype by fall 2014, final layout by mid-2015 • 38000 chips for MCH needed • Sao Paolo Microelectronics lab / Universities

  7. MFT detector in a few words. Precision of the tracking: ~10 mm. 3000 charged particles per unit of rapidity. Complex integration. Most critical aspects are being addressed.

  8. ALICE - ZDC • Attivita’ in corso: • modificameccanichecalorimetri per protoni. ZDC in superficie. • Sostituzionepartitori • Re-istallazione in caverna: fine agosto. • Riduzione del tempo morto: modifica ZRC • Attivita’ prevista: • Recommissioning

  9. Richieste ALICE Cagliari 2015 MISSIONI: 145.5 CONSUMO: 59 TRASPORTI: 2 LICENZE: 2 • Richieste DOTAZIONI: simile alloscorso anno

  10. Richiesteimpegnoservizi • Meccanica • Arba 50 • La Delfa 30 • Tuveri 40 • Elettronica • Marras 40

  11. Scientific Production of run#1 From Alice publications in inspire-hep 8 publications in Pb-Pb and p-Pband 7 in pp (1 muon publication per ~6 ALICE publications) In Pb-Pb: • Quarkonia: Upsilon (arXiv:1405.4493), J/y (arXiv:1311.0214, arXiv:1303.5880, arXiv:1209.3715, arXiv:1202.1383) • Heavy flavours: Single muon (arXiv:1205.6443) In p-Pb: • Quarkonia: J/y (arXiv:1308.6726), y(2S) (arXiv:1405.3796)
