    "abstract": "To establish the electron energy distribution function (EEDF), the second\nderivative of a Langmuir probe current-voltage (I-V) characteristic is\nnumerically integrated using the Tikhonov singular value decomposition\nregularized method. A comparison of the numerically intagrated EDDF and by a\nleast-squares fitting is discussed. The used I-V haracteristic is measured in\nan ECR plasma source using a cylindrical probe and the plasma parameters are\ndetermined by the Laframboise theory. This technique allows a rapid analysis of\nplasma parameters at any gas pressure. The obtained EEDF, for the case of the\nECR plasma source, shows the existence of two groups of electrons with\ndifferent temperatures. This result is associated with the collisional\nmechanism heating taking place in ECR plasma sources, where low pressure plasma\nis sustained by electron impact ionization of the ground state molecules or\natoms by energetic electrons arising in the resonance zone.",
