We present a statistical study of the spectral characteristics of protons in the Earth's plasma sheet for various geomagnetic disturbance levels. The study is based on more than 2000 hours of data combined from the Cluster RAPID and CIS instruments obtained during the tail season (July-October). Whereas the lower energy range considered is typically well reproduced by Maxwellian energy spectra, the higher energies often deviate significantly from such a distribution, and is better represented by a κ distribution. The actual spectral slope depends on various magnetospheric driver parameters. During disturbed conditions, a significant hardening of the spectra is observed. Periods with high solar wind pressure also characterized by a much harder spectra. Unlike the electron spectra, we do not see any local time dependence in the proton spectra.
