Abstract

An outstanding problem of solar and heliospheric physics is the transport of solar energetic particles. The more energetic particles, those arriving early in the event can be used to probe the transport processes. The arrival direction distribution of these particles carries information about scattering during their propagation that can be used to test models of interplanetary transport. Also, of considerable importance to manned missions is the dose that the crews experience during an intense solar particle event, as well as the risk to space systems. A recent study concludes that 90% of the absorbed skin dose results from particles in the energy range 20-550 MeV[1]. We will describe a new compact detector concept that would cover the energy range from 50- 600 MeV with a single detector. This energy range has been difficult to cover and only limited data, generally available only in broad energy bins, are available from a few past and present instruments. The SEPS concept could provide improved measurements for this energy range.
