Monte Carlo methods to model radiation transport are now extensively used to model detector efficiency and response for space radiation sensors. Often, the modeling efforts focus on the response of the sensor to isotropic or unidirectional fluxes at low to moderate counting rates. This is acceptable for situations where the design requirements of the sensor allow it to be operated in these...

On the Zugspitze mountain (2650 m a.s.l.), Germany, the Institute of Radiation Protection operates a Bonner Sphere Spectrometer (BSS), running continuously since 2004, to measure the neutron energy distribution of secondary cosmic rays. These measurements are highly affected by various environmental parameters, and in particular by the amount of snow in the near environment. To quantify this...

28. NASA Shields-1: A Radiation Shielding Experiment developed with Radiation Modeling

Dr Laurence Thomsen (NASA LaRC)

11/29/18, 2:50 PM

NASA Shields-1 will be launched in the upcoming NASA CubeSat Launch Initiative (CSLI) ELaNaXIX Mission in December 2018. Shields-1 hosts a research payload experiment with 8 μdosimeters behind radiation shielding in slab geometries to make dose-depth curves. Shields-1 hosts atomic number (Z)-graded radiation shielding materials as part of the research payload with baseline aluminum materials...

7. Geant4 Simulations of Space Radiation Sensors and Environment at The Aerospace Corporation

Dr Mark Looper (The Aerospace Corporation)

Geant4 is a vital tool for understanding and calibrating the response of space-borne radiation sensors at The Aerospace Corporation, and for understanding the space radiation environment that they measure. In the year and a half since the last Geant4 Space Users Workshop, the greatest fraction of our effort addressing sensor response has gone into the implementation and benchmarking of the...
