Future Space Missions
International Space Station Alpha Magnetic Spectrometer - AMS Aim: Cosmic Ray studies • Cherenkov counters • scintillators • Silicium trackers USA, Russia, Japan, ESA, Canada, Italy and Brazil Institute for Space Sciences is involved in: - electronic design for the tracker - assembling of the silicon ladders for the Tracker. - works to qualify the components for operating in a cosmic radiation environment by activities at: INFN Perugia, Italy and GSI installation, Darmstadt, Germany
ISS is involved in the investigations of the implications of the CMB measurements on the structure formation models, addressing the following scientific problems: Ø Constraints on the total density of Dark Matter components. PLANCK Mission European Space Agency Ø The imprint of the Hot Dark Matter component on the CMB power spectra. Ø Determination of cosmological lepton and baryon asymmetries. Ø Implications of neutrino oscillations on the CMB angular power spectra. Ø The implications of unstable neutrino on the CMB anisotropy. Ø Constraints on the fundamental cosmological parameters from Planck 19 data.
Planck/LFI Data - House Keeping and Science Telemetry Raw classes data from ground and Space based instrument: Ø House keeping telemetry - a set of data where all information about instruments and its devices are stored; - is aimed at: - understanding if the instruments and devices are working correctly; - giving the possibility to modify the instrument set-up in real time to quickly avoid error or device breakdown - Real Time Analysis (RTA). Ø Science Telemetry - the real science data - is aimed at understanding the goodness of science data obtained; - its output should be a set of parameters necessary to tune the instrumentation as best as possible. ü INAF – Osservatorio Astronomico di Trieste, ü C.

Laboratory of High Energy – ЛВЕ 1. Started in 1956 Ø the first stack of emulsion was exposed in the proton beam of 9 Ge. V Ø mesons of 60 Ge. V from Serpuhov. 2. Along 45 years of a strong collaboration Ø many other stacks were exposed with different high energy nuclei (He, C, N, O, Ne, Si, S) at the syncrofazotron E = 4. 5 AGe. V Ø secondary radioactive beams at the nuclotron (He 3, Be 7, B 10, B 11). As a result over 100 articles were published in different prestigious journals of great impact, only this year we came with 3 papers. At present we continue to work in emulsion, and are mostly interested in the Becquerell project, because it is aimed to solve crucial problems for nuclear astrophysics.
2. Another collaboration with ЛВЕ begun 5 years ago, concerning ALICE experiment at LHC-CERN. 3. This year we will start the third direction = the investigation of secondary particle production and neutron yield from heavy targets in nucleus-nucleus interaction and study of transmutation of radioactive wastes from nuclear power installations. In order to strenghten our collaboration with ЛВЕ we send for a long period to work in Dubna 5 very young people from our laboratory, which will arrive here next month.
