Workshop topics:
- High energy electron observations below L=4
- Wave-particle interactions inside and outside the plasmasphere
- Radial diffusion, stochastic transport and non diffusive transport in the inner belt and slot region
- Injection of high energy electrons into the plasmasphere and dropouts dynamics
Main scientific questions to be addressed (sorted by topics):
1. High energy electron observations below L=4
- Can relativistic and ultra relativistic electrons penetrate inside L=4?
- Do the new RBSP measurements show ultra relativistic electrons below L=3?
2. Wave-particle interactions inside and outside the plasmasphere
-
- What are the dominant local wave-particle interaction mechanisms inside L=4?
- How low in L can Chorus waves contribute to acceleration during time of extensive plasmasphere erosion?
3. Radial diffusion, stochastic transport and non diffusive transport in the inner belt and slot region
-
- What are the properties of radial transport in the inner belt?
- How do electron loss mechanisms compare between the outer and the inner belt?
4. Injection of high energy electrons into the plasmasphere and dropouts dynamics
-
- How low in L can dropouts remove an important part of the electron population?
- What happens at the plasmapause for highly compressed plasmasphere during storms?
Transverse questions:
- How important are processes in plasmaspheric plumes?
- How do multiple belts or storage rings form, persist, and decay?
- Do any events isolate individual mechanisms?
Scientific means:
- Computational codes: Fokker-Planck codes, PIC codes embedded in dynamics Earth magnetic/electric fields, massively parallel codes
- Access to Van Allen Probes satellite data
- Data processing codes
