摘要
Electron energy distribution functions of plasmas were calculated by digital processing from Langmuir probe characteristics. The method used is based on the least squares priciple for fitting the experimental data to a polynomial curve, and performs the differential operation by a convolution of data with weighting functions. The computer program developed in accordance with this method was applied to the probe characteristics of positive column plasmas. The results were compared with the Maxwellian and Druyvesteyn distribution functions. © 1990 IOP Publishing Ltd.
