1. A method for diagnosing a local plasma with a single Langmuir probe into the plasma by introducing small gas discharge electrodes, for example the segment metal filament that is connected via a variable voltage source to the metal body of gas discharge devices or additional reference electrode with the adoption of the probe circuit protection measures against electrical interference, cleaning the collecting surface of the probe, recording its current-voltage characteristic when changing the voltage on both sides of the floating potential and determines in the density of electrons, their temperature and spatial processing plasma potential probe characteristic based on the known theories, for example, by Druyvesteyn, characterized in that for each of the current-voltage characteristic of the probe is measured the difference between the plasma potential and the floating probe potential and the found value functionally dependent the ion mass M, determine the effective mass of ions collected by the probe MnO formula describing the potential difference measured expression matching conditions ex erimenta.2. The method of claim. 1, characterized in that in the case of non-isothermal plasma express the measured potential difference with the Bohm effect formula, wherein T and m- temperature and mass of the electron, respectively, and the coefficient K in the formula Bohm ion saturation current density (here e - elementary charge, T- electron temperature in electron volts, and m- mass Mi in the same units of ions and electrons), whose size detected in a special experiment with guaranteed clean plasma-forming substance with a known value of M, and in subsequent experiments
