The ion differential spectra in outer boundary of the ring current: November 17, 1995 case study

The analysis of the ion spectra variations is presented for the particles in the energy range from 0.5 keV to 3 MeV during INTERBALL-Tail Probe crossing of the plasma sheet-ring current region on November 17, 1995. The CORALL, DOK-2 and SKA-2 instrument data were used for spectra restoring. It is shown ion spectra have the same smooth shape (with the averaging time ∼2 min ) by traversing the satellite from 20 R e up to 6 R e . In particular, the spectra shape was almost constant with decreasing of geocentric distance from R e =11 to 6. Possible reasons of spectra variations are discussed.
