Effect of EMIC waves on relativistic and ultrarelativistic electron populations: Ground-based and Van Allen Probes observations [PDF]

, 2014
We study the effect of electromagnetic ion cyclotron (EMIC) waves on the loss and pitch angle scattering of relativistic and ultrarelativistic electrons during the recovery phase of a moderate geomagnetic storm on 11 October 2012.

A statistical analysis of the Kappa-type energy spectrum distribution of radiation belt electrons observed by Van Allen Probes

Earth and Planetary Physics
The energy spectrum of energetic electrons is a key factor representing the dynamic variations of Earth’s Van Allen radiation belts. Increased measurements have indicated that the commonly used Maxwellian and Kappa distributions are inadequate for ...

The global statistical response of the outer radiation belt during geomagnetic storms [PDF]

, 2018
Using the total radiation belt electron content calculated from Van Allen Probe phase space density (PSD), the time-dependent and global response of the outer radiation belt during storms is statistically studied.

The Chandra X-Ray Observatory's Radiation Environment and the AP-8/AE-8 Model

, 2000
The Chandra X-ray Observatory (CXO) was launched on July 23, 1999 and reached its final orbit on August 7, 1999. The CXO is in a highly elliptical orbit, approximately 140,000 km x 10,000 km, and has a period of approximately 63.5 hours (~ 2.65 days). It

Plasmatrough exohiss waves observed by Van Allen Probes: Evidence for leakage from plasmasphere and resonant scattering of radiation belt electrons [PDF]

, 2015
Exohiss waves are whistler mode hiss observed in the plasmatrough region. We present a case study of exohiss waves and the corresponding background plasma distributions observed by the Van Allen Probes in the dayside low-latitude region.

Clementine undergoing radiation test of Van Allen Belts

Eos, Transactions American Geophysical Union, 1994
Plans for the joint Department of Defense (DoD)‐NASA spacecraft Clementine to continue to film the asteroid Geographos have been officially canceled.Yet project scientists are using the opportunity to test how the robot spacecraft fares in Earth's radiation belts. There is speculation that the twenty‐three experimental technologies aboard the craft may

The ring current, geomagnetic disturbance, and the Van Allen radiation belts [PDF]

Journal of Geophysical Research, 1961
The large decrease in the horizontal component of the earth's field during the main phase of magnetic storms is ascribed to the formation or enhancement of a geomagnetic ring current. The motions of particles trapped in the earth's dipole field and the resulting ring current are discussed. These calculations deal only with a steady state, though during

Reproducing the observed energy‐dependent structure of Earth's electron radiation belts during storm recovery with an event‐specific diffusion model

Geophysical Research Letters, 2016
We present dynamic simulations of energy‐dependent losses in the radiation belt “slot region” and the formation of the two‐belt structure for the quiet days after the 1 March storm.
