Geant4 hadronic physics for space radiation environment.
PURPOSE To test and to develop Geant4 (Geometry And Tracking version 4) Monte Carlo hadronic models with focus on applications in a space radiation environment. MATERIALS AND METHODS The Monte Carlo simulations have been performed using the Geant4 toolkit. Binary (BIC), its extension for incident light ions (BIC-ion) and Bertini (BERT) cascades were used as main Monte Carlo generators. For co...
متن کاملUsing semantics to extend the space physics data environment
The space physics data environment is evolving with the advent of virtual observatories. With the primary function of most virtual observatories being data search and retrieval, an emphasis has been placed on providing value-added data processing services. That is, creating web services that take discovered data and provide common and routine processing such as coordinate transformations and da...
متن کاملSUNVIZ: A Real-Time Visualization Environment for Space Physics Applications
Real-time physically accurate simulations are difficult to create because of limited computational power available on a CPU. General purpose computing on the graphics processing unit (GPU) can provide a significant increase in performance. We are able to investigate the flow characteristics of a cloud of charged particles, which is one of the first steps in our goal of generating a real-time Co...
متن کاملThe physics of the space elevator
A space elevator is a tall tower rising from a point on the Earth’s equator to a height well above a geostationary orbit, where it terminates in a counterweight. Although the concept is more than a century old, it was only with the discovery of carbon nanotubes that it began to receive serious scientific attention. NASA commissioned a study of the space elevator in the late 1990s that examined ...
متن کاملSpace Environment and Evaluation of Typical High Altitude Satellite
The space environment consists mainly of high-energy charged particles, such as protons, electrons and heavy ions. They are originating from several sources including galactic cosmic radiation, solar flares and van Allen belts. High energy electromagnetic radiation and neutrons have also been measured on spacecraft. Although shielding can reduce the effect of space radiation it cannot be elimin...
