Electron Intensity Measurements by the Cluster/RAPID/IES Instrument in Earth's Radiation Belts and Ring Current

The Ring Current, Geomagnetic Disturbance, and the Van Allen Radiation Belts

The large decrease in the horizontal component of the earth's field during the main phase of magnetic storms has been ascribed to the formation or enhancement of a geomagnetic ring current. In this paper we discuss the motions of particles trapped in the earth's dipole field and the resulting ring current. These calculations deal only with a steady state, though during storms the state is chang...

Relativistic electron acceleration and decay time scales in the inner and outer radiation belts: SAMPEX

Ab__•S_.•_• High-energy electrons have been measured systematically in a low-altitude (520 x 675 km), nearly polar (inclination = 82 ø) orbit by sensitive instruments onboard the Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX). Count rate channels with electron energy thresholds ranging from 0.4 MeV to 3.5 MeV in three different instruments have been used to examine relativistic...

Measurements of the Electron Cloud in the Aps Storage Ring

Synchrotron radiation interacting with the vacuum chamber walls in a storage ring produce photoelectrons that can be accelerated by the beam, acquiring sufficient energy to produce secondary electrons in collisions with the walls. If the secondary-electron yield (SEY) coefficient of the wall material is greater than one, as is the case with the aluminum chambers in the 7-GeV Advanced Photon Sou...
