Abstract
This paper reports about the bi-Maxwellian nature of electrons in a filament discharge plasma that exist in a suitable working pressure range. The plasma is produced within a multidipole magnetic cage with a stainless steel mesh grid connected at one end of the cage. The variation in electron energy, plasma potential and electron energy probability function are studied by applying different bias voltage to the magnetic cage, mesh grid and the filaments. It is observed that the electron energies are highly influenced by the bias applied to the magnetic cage and the filaments. The plasma potential is found to be mostly affected by the cage bias voltage. A plane Langmuir probe is used to estimate the plasma parameters.
