アブストラクト The arbitrary electron energy distribution function (EEDF) of a cold atmospheric-pressure plasma is determined from optical emission spectroscopy measurement. Using the electron-neutral bremsstrahlung-dominated continuum spectrum and relevant cross section data, a partial arbitrary EEDF can be reconstructed through the reinforcement learning-based visible bremsstrahlung inversion (VBI) method. From an atmospheric-pressure argon dielectric barrier discharge plasma emission spectrum (440-900 nm), a partial arbitrary EEDF can be determined with a resolution of 0.2 eV. Resemblance between the obtained arbitrary EEPF and a two-temperature Maxwellian was found with T_e = 0.26 and 2.2 eV. The EEDF range is mostly constrained by the spectrum wavelength range.
