Electron temperature variation over the magnetic filter region and the extraction region is investigated theoretically. We assume qx/{(5/2)TΓx}=β between heat flux qx and electron flux Γx, where β is a ratio of the heat flux to the enthalpy flux and T is the electron temperature. Terms of diamagnetic drift in the expressions of the flux and heat flux are important in obtaining temperature T(x) that agrees with Haas et al.'s experimental results. Electron loss along the magnetic field is important in determining the exponential dependence of the electron number density and temperature on y. Flux inversion is attributed to the negative flux due to the electric field.
