  1. CAP Space Projects Martin Pohl Journée de réflexion du DPNC 18 juin 2012

  2. CAP Genève Science Physique des astro-particules: • Rayons X, photons, rayons cosmiques • Neutrinos, ondes gravitationnelles • Sources astronomiques et cosmologiques • Accélération et propagation • Sources non conventionnelles: matière noire, énergie sombre Convergence intellectuelle et technologique Astrophysique de haute énergie Cosmologie Physique des particules

  3. INTEGRAL Instrumentation ATLAS AMS FUTURE: Cherenkov Telescope Array CTA

  4. CAP Genève • Membres fondateurs: Thierry Courvoisier (ISDC, Observatoire), Ruth Durrer (DPT), MicheleMaggiore (DPT), Martin Pohl (DPNC) • Ouvert à tous les chercheurs de ce domaine, de l’Université de Genève et des autres acteurs de la région (CERN, EPFL etc.) • Fonctions: • Forum d’échange scientifique • Projets d’intérêt commun, existants (INTEGRAL, AMS, POLAR, ASTRO-H…) et futurs (EUCLID, CTA…) • Réunions mensuelles, revue des projets communs • Dissémination de résultats, séminaires et conférences • Ressources: • Ressources existants des partenaires (UniGe, SNF, SSO etc.) • Postes COB • Minuscule budget de fonctionnement • Pas de nouvelle structure administrative

  5. CAP Genève Space Projects • Data taking phase: • Integral: data center at ISDC ESA • AMS on ISS: AIV at DPNC, complete integration, operation and data center at CERN NASA • Construction phase: • POLAR, polarimeter for Tiangong 2, CAP + PSI GESSA • ASTRO-H, filter wheel mechanism, CAP + RUAG JAXA • Assessment and definition phase: • JEM-EUSO on ISS JAXA • LOFT (M3 candidate) ESA • DAMPE GESSA • Conceptual design phase: • HERD (next step beyond AMS and FERMI) GESSA • All phases, all major players

  6. AMS-02 Launch STS-134 Endeavour: • Successful launch: May 16, 14:56 • Docking with ISS: May17, 17:59 • AMS installation complete: May 19, 11:46 • AMS up and running: May 19, 16:38 • First He nucleus: May 19, 16:42

  7. POLAR Instrument Polarimeter: • Photon polarisation from GRB • Hard x-rays, 50 keV < Eγ < 500 keV • FoV 30% of sky • Flight opportunity TG2 (n.e.t. 2014) OBOX (Europe): • 5x5 modules in carbon fibre box • Central trigger and power supplies IBOX (China): • Space craft interfaces • Central computer

  8. Tiangong Mission Progress • 29 Sep. 2011: Tiangong 1 launched onboard Changzheng 2F-T1 vehicle • 360km near circular orbit • Controlled descent to a 343km near-circular orbit under atmospheric drag • 30 Oct. 2011: 180° turn with its docking port pointing backwards • 2 Nov. 2011: First docking with unmanned Shenzhou 8 spacecraft, two vehicles flew connected in orbit for 10 days • 17 Nov. 2011: Shenzhou 8 returned to Earth • 16 June 2012: Shenzhou 9 manned mission to Tiangong 1

  9. POLAR OBOX Interface connectors CFRP Top Cover 25 modules POLAR module Electronic board housing OBOX Base Plate • 25 modules (64 bars each) • Bar length: 176 mm • FEE included in the module • Load factor to be applied: ~ 20g • Temperature range: [-40°C,+50°C] • Weight: 30 kg, power: 50W • Dimension: 250 x 450 x 450 mm3 Back plate

  10. POLAR Module CFRP socket (1mm thick carbon prepreg) Back seal End Cap 64 Bars PMT FEE Baffles FEE EQM version (with PSI in Zurich)
