5/1/2014 Seminar – Radiation belt precipitation: an overview of mechanisms and recent simulation results – cancelled

Location: SPSC W120

Seminar Abstract:

Radiation belt precipitation has been investigated since their discovery by Van Allen. This kind of loss is a major sink for the energetic particle population in our magnetosphere. There are many types of wave-particle interactions and other phenomena that can cause these particles to be lost to the atmosphere. I will give a brief overview of radiation belt precipitation, focusing on energetic electron precipitation and including the several mechanisms by which it can take place. I will also present the results from recent modeling efforts using MHD modeling of the magnetosphere coupled with test particle simulations to understand its possible causes.
