The International Space Station Ionizing Radiation Environment: Electronic Systems, Materials, and Shielding Mass Effects
Year: 2016
Type: article
Abstract: Outline 2• 1) Space Radiation: What is it, where is it, and why is it so hard to manage?-The space radiation environment is radically different from Earth surface radiation environments -Space radiation effects are determined primarily by highly energetic (often relativistic) charged particles -the term "ray" is an historical misnomer from the early 1900s • Galactic cosmic "rays", solar particle events, and radiation belts -high energy (fast) charged particles and a few high energy photons dominate the environment • 2) How does space radiation interact with matter (i.e.us and our stuff) -Direct Ionization/Excitation (Particle Tracks) -health effects and microelectronics, materials -Nuclear Reactions and Secondary Particle Showers (and more ionization tracks)health effects and microelectronics -Displacement damage -Optoelectronics (solar cells, light emitting diodes, photodiodes etc.• 3) Space Station Zero -Space Radiation Shielding Specification, Shielding Mass, and Magnetic Shielding in Perspective with humanities oldest spacecraft -Shielding Mass and Magnetic field -Shielding performance -Earth Surface Environments -Shielding performance -Commercial and Military Aircraft Environments • 4) International Space Station -Space Radiation Shielding Specification, Shielding Mass, and Magnetic Shielding -Geomagnetic field -Spacecraft Shielding Mass -Shielding performance -electronic systems -internal and external -Shielding performance -surface materials • 5) Summary and Conclusions • 6) Supporting Information and References -A listing of space radiation environment, transport, and analysis/modeling tools and where to obtain them • Monte Carlo Simulators -FLUKA and related Monte Carlo codes • Boltzmann codes -CRÈME-96, HZETRN 2015 -A short bibliography and resource list
