  1. UuuuuuUuuuuuuuuuu Roberta Sparvolifor the PAMELA Collaboration University of Rome Tor Vergata and INFN Roma II, Italy

  2. PAMELA scientific program PAMELA is a magnetic spectrometer which will fly on a Russian satellite by Fall 2005. Its scientific scope is the measurement of the antiproton and positron spectra up to few hundred GeV, of the proton and electron spectra up to 700 GeV and that of light nuclei. energy rangeparticles/3 years Antiproton flux 80 MeV - 190 GeV >3 104 Positron flux 50 MeV – 270 GeV >3 105 Electron flux up to 400 GeV 6 106 Proton flux up to 700 GeV 3 108 Electron/positron flux up to 2 TeV Light Nuclei (up to Z=6) up to 200 GeV/n He/Be/C: 4 107/4/5 AntiNuclei search (sensitivity of 3 10-8 in He/He) • Unprecedented Statistics and new Energy Rangein CosmicRays Actual limits: antip&positrons  40 GeV R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  3. Flight Model – Munich, Jan 2005 What is PAMELA now? R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  4. Mass&Thermal Model in TsSKB Pressurized Container Integration in the Container Mass & Thermal Model PAMELA Mass & ThermalModel was assembled in the clean room of Rome Tor Vergata (2001-2002) and then integrated into the Pressurized Container at TsSKB-Progress (Samara/Russia), between March 2002 and April 2003, for all mechanical compatibility tests. It passed thermal and dynamical qualification tests. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  5. Technological Model PAMELA Technological Model was assembled and tested (preliminary Acceptance Tests with EGSE: power ON/OFF, telecommands, data transmission through adapter) in the clean room of RomeTor Vergata in 2003-2004. It was then shipped to Samara inside a special transport container in April 2004. Magnetic compatibility tests and Incoming Tests (stand-alone) already performed. Integration with satellite and transmission to mass memory still in progress (Jan 2005). R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  6. PAMELA-FM inside Transport Container Design: > 5000 km flight & 1000 km rail, +40/-50°C outside Flight Model Integration The final Flight Model integration is in progress in Rome clean room since almost 12 months. All flight components have been mounted. From 16/02/2005 a Russian delegation is in Rome for official Acceptance tests of PAMELA FM before delivery to Samara. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  7. SPS, July 2000 Magnet/Tracker, Calorimeter SPS, September 2003 SPS, July 2002 Beam tests From July 2000 until September 2003 PAMELA Flight Model was extensively exposed to beam tests to study physical performance. Detectors operated at CERN PS/SPS test beams as prototypes and in FM configuration. Final test in Sept. 2003. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  8. Risposta ricerca di risonanza asse Z per accelerometro MP 14 (montante) Dynamic tests PAMELA FM Model passed acycle of vibration tests at IABG/Munich (January2005) to verify the final structure. Minimal loads have been imposed to the instrument. 100 channels were mounted. All resonance searches confirm the integrity of the detector after the test. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  9. Cosmic ray tracks (Dec. 2004) Since November 2004 PAMELA is set in cosmic-ray acquisition during night shifts. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  10. First “physics” results From the statistics acquired by cosmic-ray acquisitions we are analyzing PAMELA performance and comparing with literature. R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  11. Conclusions – already done (0) Detectors and Systems are designed & ready (1) MASS & THERMAL MODEL done  All tests passed space qualification! (2) TECHNOLOGICAL MODEL ~ done  Assembly finished in Rome (~1 yr)  Integration with satellitein Samara almost complete (started 05/2004) (3) FLIGHT MODEL  SPS BeamTest of almost complete setup done in Sept. 2003 for final calibration & alignment  done  Vibration Test(minimal loads) of complete setup for final check of structure – Munich (Jan. 2004) done R. Sparvoli - INFN-SPAZIO/2 - LNF, 16 Febbraio 2005

  12. Conclusions – to be done FLIGHT MODEL  Acceptance tests to be performed (end by 23Feb. 2005)  Cosmic-ray acquisition (long run)(end by 10 March 2005)  Transport to Samara – Russia (March 2005)  Full integration ofPAMELA, ARINA & EOS into satellite (April 2005) Tests in Samara – Russia (up to 3 months)  All final tests in-situ - Baikonur/Kazahstan (2 – 3 months) The PAMELA launch isin Fall 2005 R.
