  2. Particlesphysicstechnologies • ThephysicsofRadiationinteractionwithmatter • Dosimetry • Detectorsandinstrumentation • Software development • Detectorsimulation • Systemcontrol • data analysis • imagerecontruction • Beamlinesandaccelerators

  3. RadiationEnvironment in the Solar System Galactic Cosmic Rays low flux but highly penetrating Solar Particle Events sporadic, intense & dangerous Radiation Belts high radiation dose protons & nuclei electrons & protons electrons , protons & ions

  4. SpaceRadiationenvironmentandeffects • Radiationenvironment in spacedescriptionandstudy • Radiationdamage to systems, componentes andcrews: • Testingandmodeling • Radiationmeasurement • for spacecrafthousekeeping • for scientificpurposes: planetaryenvironments, mannedmissions, astrobiology …

  5. JUICETheJupiterIcyMoons Explorer NextClass-L (Large) ESA Mission Synchrotronemissionobservations & data fromVoyagers, Pioneer , Galileo, Cassini

  6. Jovian Rad-Hard Electron Monitor Proto-Flight Model ESA/ESTEC Contract 1-7560/13/NL/HB EFACEC,LIP, RUAG,PSI,IDEAS RADEM – a Radiation Monitor for the Jovian System • Electron detector: • spectral range 300 keV – 40 MeV, • peak flux 109 e/cm2/s • Proton and Heavy Ion detector: • spectral range 5 MeV – 250 MeV, • peak flux 108 p/cm2/s • Particle separation from Helium to Oxygen; LET spectra • Radiation hard,dose determination and alarm function LIP is in a consortium for phases B2, C and D, to develop, qualify and build RADEM PROTO-FLIGHT MODEL

  7. Radiation Environment Modeling MarsREM: the Mars Energetic Radiation Environment Models LIP developed dMEREM, a Geant4 based model for the radiation environment on Mars, Phobos and Deimos, including local treatment of surface topography and composition, atmospheric composition and density (including diurnal + annual variations) and local magnetic fields. Inputs given as a function of latitude, longitude, in a 5 x 5 degree grid, and season. Example of dMEREM results: Particle radiation arriving on Mars surface after GCR-alpha interaction with atmosphere and soil 7

  8. ...it is possible ! It is possible to remain in Martian surface for some time with no serious risk for the astronauts! For longer permanences shelters are required... 28/06/2018 8

  9. ESA JUICE mission • RADEM – Radiation Hard Electron Monitor • EEE component testing for Jovian environment LIP ESA contracts ESA Mars Energetic Radiation Environment Models • GEO Radiation Environment: • Radiation Environment Measurement (MFS) • EEE component test bed (CTTB)

  10. What do Space & biomedicalapplicationshave in commoN?

  11. RADIATION http://spaceweather.com/

  12. Radiation BIOMEDICAL APPLICATIONS • Diagnostics • Treatment • R&D onnewdevicesandtechnologies

  13. Therapy with hadrons • Proton/ion therapy • energetic protons/ions are produced in an accelerator • energetic protons/ions are directed at the tumor • Varying the energy of the protons/ions results in good deep control • Beam can be focused to the size of a pin • less damage to healthy tissue than electron or gamma therapy Source: Radiological Society of North America, Inc (http://www.radiologyinfo.org)

  14. Therapywithhadrons therapeutic application of accelerators particle-based radiotherapy, including protons and heavy ions

  15. MAster theses themes • Modelling of the Lunar Radiation Environment • Simulation of AlphaSat Radiation Environment and Effects Facility Component test bed and analysis of in-flight data • Radiation Effects in EEE components in Geostationatry Orbit • Simulation of Galactic Cosmic Rays (GCR) induced damage on DNA molecules • Design and study of a tissue equivalent plastic dosimeter for applications in hadrotherapy and space • … patricia@lip.pt
