  15. Status of ALICE – Summer 2009 100% TPC 80% HLT 3/5 PHOS

  16. Time Projection Chamber - TPC • Norwegian in-kind contribution to FEE • Status • The TPC in its final position at P2 was successfully commissioned in 2008 with Krypton gas, laser tracks and cosmics • Currently services are being reconnected

  17. Time Projection Chamber - TPC The Norwegian groups participated • in the development • of the read-out electronics (read-out controller unit), • of the trigger electronics (busy box) • and of the field layer of the DCS for the FEE, • in the integration of the TPC into the Trigger, HLT and DCS systems, • in the installation of the FEE and • in the commissioning.

  22. PHOton Spectrometer - PHOS • Norwegian core contribution to read-out chain • APD + preamp + T-card • FEE, trigger • Status • The first module had been commissioned and calibrated with cosmics in the PHOS-lab in 2007 and at P2 (in its final position) in 2008, although it had not been not cooled down to -21 degrees. • At the end of 2008 it was removed from the pit. This module and two further modules are now being inserted into air-tight casings, re-assembled, tested and installed at P2.

  23. PHOton Spectrometer - PHOS • The Norwegian groups contributed to the development of the read-out electronics (preamplifier, front-end and trigger electronics and read-out controller unit). • They participated in the integration of PHOS into the Trigger, DAQ, HLT and DCS systems, in beam tests and in the commissioning in the lab and at P2. • They have supplied accompanying simulations of the physics capabilities, detector performance and trigger selectivity and rates. • Summary of activities/achievements in 2007-2009(Per-Thomas Hille, OD, DL, KS, LL): • DCS for the FEE • Integration with DAQ, ECS, Trigger and DCS • Firmware design of the FEC board controller • Firmware design of the L0 and L1 trigger generation • Commissioning the first module • Calibration of the first module with cosmics • Development of online data processing, filtering and trigger algorithms • Development of online monitoring and calibration tools

  24. High Level Trigger - HLT • Norwegian corecontribution to the HLT cluster • Status:The first phase of the HLT installation is completed: full detector connectivity. • All interfaces to other subsystems are in place; • tested reconstruction chains are available.

  25. High Level Trigger - HLT • Summary of activities/achievements in 2007-2009 • Methods and algorithms for an on-line selection of (rare) signals (KK, MR, SB, KA, GO, OD) • TPC • PHOS • A common HLT analysis framework has been developed that allows to run online code inside the AliROOT offline framework and vice versa (MR) • Interfaces to all other relevant subsystems, i.e. ECS, DCS and OFFLINE have been developed, implemented and tested (SB) • We also contribute to the cluster management and the online monitoring of the HLT system (ØH)

  26. Preparing for physics analysis • Study of flow phenomena in pp collisions (JM), study of the ALICE detector performance for elliptic flow measurements, study of possibility to measure directed flow • Correlations (JM, MN) • Study of gamma-hadron jets (SL) • Reconstruction of neutral pions via gamma conversions in the TPC (KA) • Online reconstruction of open charm (GO) • Transverse neutral energy production in p+p and A+A collisions (OD) • Study of two-photon and photonuclear processes in ultra-peripheral collisions at the LHC (KS)

  27. Theory • The Bergen group continued the development and testing of our hybrid 3D-hydrodynamical models for QGP scenarios: a Multi-Module Model for describing the reaction’s initial preequilibrium stage, the intermediate thermally equilibrated hydrodynamical stage, and the final freeze-out stage. The main goal was to incorporate the Constituent Quark Number (CNQ) scaling in the hydro calculations, and Freeze-Out. • The Oslo group studied the possible thermalization and Equation of State of hot and dense nuclear matter in heavy-ion collisions within the microscopic transport models, the collective anisotropic flow and two-particle correlations. The group also worked on a fast MC Generator, implemented in ALIROOT, which contains a statistical model, PYTHIA, jet quenching and flow with impact parameter dependence; on the implementation of cold nuclear effects from Glauber Gribov Theory in HYDJET-generator and on the production of heavy quarkonium.

  28. ISOLDE • 2006 • 2007 • 300 kNOK ISOLDE membership fee • 2008 • 300 kNOK ISOLDE membership fee • Since 2007 • ISOLDE theory (Jan Vaagen, Morten Hjorth-Jensen, Eivind Osnes) supported by the ALICE project
