Interplanetary Physics Branch/Code 692
Magnetospheric Electron-Density and Magnetic-Field-Strength Values
from the Radio Plasma Imager (RPI) on IMAGE
December 2000 AGU Meeting, San Francisco, CA
R. Benson, J. Fainberg, V. Osherovich - Code 692/J. Green & S. Fung - Code 630

• RPI plasma resonance Spectrum depends on:

  
  

  - Plasma frequency f_pe (related to electron density)

  
  

  - Cyclotron frequency f_ce (related to magnetic field)

• RPI spectral data (below) indicates:

  
  

  - Model f_ce is accurate to within 10 percent

  
  

  - Model f_pe can be in error by > a factor of 10
