  1. EMCal – France Status report, July 2008 • Manpower • Technical activities • Physics analyses 1 Status in France - July 2008

  2. EMCal – France manpower Status in France - July 2008

  3. EMCal – LPSC technical tasks SM assembly & calibration • Module construction (J.F. Muraz) • Construction of strap foils for 3 SMs • ~ 1/3 machined and delivered to welding company • StripModule & SuperModule tools (J.F. Muraz) • StripModules handling tooling : ready to be sent to Yale • Production of 4 SuperModule platforms • Cosmic calibration test bench (JFM, JSR, CF, SG, PC, RG …) • 16 scintillator paddles under construction • Electronics (CFD, coincidence trigger, CCUSB …) almost available • DAQ installed at LPSC (thanks to T. Awes, D. Silvermyr) • Overall setup to be ready for end of September Status in France - July 2008

Bourrion) • L0 : OR of all L0 provided by the TRU • L1-gamma trigger ( 4x4 tower) • L1-jet trigger ( nxn subregions compared to V0 threshold) • Status of STU • First STU board under construction, expected for end of July 2008 • Tests of functionalities scheduled for September 2008 (TRU-STU link) • DCS : PVSS first implementation for the end of 2008 • V0 threshold : preliminary discussion with IPN Lyon Status in France - July 2008

  5. EMCal – LPSC analysis tasks • Testbeam analysis (R. Guernane) • Study of LED dependence versus temperature • Provide temperature correction over the whole testbeam period • Cosmic test analysis(S. Gadrat, P. Carrivain) • Define the analysis procedure for muon calibration • Detailed comparison with simulation • Electronics mapping tools (R. Guernane) • Provide mapping tools (from tower to STU) for simulation & analysis • PPR expected involvement • EMCal triggering (R. Guernane, C. Furget) • Electron and Heavy flavor (S. Gadrat) Status in France - July 2008
