简介
Statistical results from a survey of 93 passes through the high‐latitude extension of the plasma sheet of electron data from the Hydra instrument on the Polar spacecraft show that the values for electron density can range from 0.01 to 0.5 cm−3 with an average value around 0.1 cm−3 on the poleward side and 0.3 cm−3 on the equatorward side. Electron mean energy is found to have an average value near 900 eV on the equatorward side and 400 eV on the poleward side but varies from 100 eV to 4 keV. These values for density and mean energy are similar to those reported for measurements made in the equatorial plasma sheet by several previous spacecraft. The character of the electron distributions has been compared with Maxwellian and κ‐distributions with the result that the κ‐distribution with κ ≤ 10 yields an acceptable fit to the data twice as often as a Maxwellian distribution. This is similar to results found in …
