The CRRES Medium Electrons A spectrometer data were used to examine the dynamics of electron fluxes in the inner zone after a series of magnetic storms increased electron fluxes by an order of magnitude down to as low as {ital L}=1.25. Comparisons of CRRES electron data with the AE8MAX particle model show good agreement in the inner zone in flux intensity, energy spectra, and pitch angle distributions up to about 600 keV pre-storm. Above 600 keV, the AE8MAX model has higher fluxes. The maximum energy spectrum over the range 0.15 MeV to 1.7 MeV observed at geosynchronous orbit altitude during the 16-month CRRES mission is presented and extrapolated to 10 MeV. The combined spectrum is characterized as the sum of three power-law segments with breakpoints at 0.8 and 2.0 MeV. The coefficients for the three segments are respectively {ital N}{sub {ital E}}=5{times}10{sup 7}{ital E}{sup {minus}1.5}, {ital N}{sub {ital E}}=4.5{times}10{sup 10}{ital E}{sup {minus}2.5}, and {ital N}{sub {ital E}}=4{times}10{sup 15}{ital E}{sup {minus}4}. Shielding of 155 mils Al equivalent would be required to prevent deep dielectric charging problems on geosynchronous satellites by an environment as severe as this maximum spectrum. {copyright} {ital 1996 American Institute of Physics.}
