Within the Earth geomagnetic field, the computation of Galactic Cosmic Rays (GCR) cutoff rigidity is a necessary step in modulating the magnitude of free space GCR ions that reach Low Earth Orbit (LEO). Traditionally, the cutoff rigidity calculation has been carried out using a computationally efficient approximation named Stormer which models the Earth geomagnetic field as a simple dipole....

21. COMPARING SPACE RADIATION GCR MODELS WITH AMS DATA

The Alpha Magnetic Spectrometer (AMS) onboard the International Space Station has recently made high precision measurements of the hydrogen and helium spectra from an energy of several hundred MeV/n up to the very high energy TeV/n region. Recent studies of space radiation transport through realistic spacecraft shielding scenarios have emphasized the importance of high energy hydrogen and...

17. Fermi Large Area Telescope observations of high-energy gamma-ray emission from Solar Flares

The Fermi Large Area Telescope (LAT) observations of the active Sun provide the largest sample of detected solar flares with emission greater than 30 MeV to date. These include detections of impulsive and sustained emission, extending up to ~20 hours in the case of the 2012 March 7 X-class flares. These high-energy flares are coincident with GOES X-ray flares of X, M and C classes as well as...
