Abstract Electron temperature variation over the magnetic filter region and the extraction region is investigated theoretically. We assume {ital q}{sub {ital x}}/{l_brace}(5/2){ital T}{Gamma}{sub {ital x}}{r_brace}={beta} between heat flux {ital q}{sub {ital x}} and electron flux {Gamma}{sub {ital x}}, where {beta} is a ratio of the heat flux to the enthalpy flux and {ital T} is the electron temperature. Terms of diamagnetic drift in the expressions of the flux and heat flux are important in obtaining temperature {ital T}({ital x}) that agrees with Haas {ital et} {ital al}.{close_quote}s experimental results. Electron loss along the magnetic field is important in determining the exponential dependence of the electron number density and temperature on {ital y}. Flux inversion is attributed to the negative flux due to the electric field. {copyright} {ital 1996 American Institute of Physics.}
