| Abstract: | The voltage-current characteristics and electronenergy distribution function (EEDF)of helicon plasma measured by a voltage swept probe in Linear ExperimentalAdvanced Device (LEAD) are presented. The profiles of some basic plasmaparameters, such as electron temperature, density, plasma potential and sheathpotential coefficient are given. It is shown that the EEDFs within a radius of 5cm conform to Maxwell distribution.However, the EEDF at the radius of7cm which is the same as that of the RF antenna has a bi-Maxwelliandistribution. This will affect some traditional measurements based onMaxwellian EEDF. |
