An overview of the theoretical modeling of acceleration of solar energetic particles at interplanetary shocks will be presented. The basic tenets of diffusive shock acceleration will be discussed in the framework of particle acceleration at coronal mass ejection-driven shocks using the Particle Acceleration Throughout the Heliosphere (PATH) code. The original PATH code was restricted to a...
There have been significantly fewer large solar proton events (SPEs) in the current solar cycle (solar cycle 24) compared to the previous one. Solar proton events occur when the flux of solar-energetic particles with energies greater than 10 MeV exceeds 10 protons/(cm2 s sr) and are reported by NOAA/GOES. Such events are usually associated with shock waves driven by fast coronal mass...
During solar cycle 24, thanks largely to the Solar Terrestrial Relations Observatory (STEREO), many solar energetic particle (SEP) events have been observed at widely separate heliographic longitudes, even including impulsive events. The particle intensity profiles sometimes show rather quick onsets after the solar event even if the measurements are made at a longitude generally considered to...
Traditionally, Galactic Cosmic Rays (GCR) models are used as a boundary condition input to the
deterministic or stochastic (e.g. Monte Carlo) based radiation transport codes with the goal of extracting
dosimetric quantities of interest such as dose, dose equivalent, effective dose, etc. at a desired target
point within the spacecraft. To compute the dosimetric quantities of interest, the...
