N2 - Judging by publications dedicated to investigating plasma using probes, investigators are constantly confronted with problems of calculating plasma parameters. There is now a certain tendency to criticize classical methods of diagnostics. True, it should be said that authors criticizing the Langmuir theory and some other methods of diagnostics sometimes do not perform gas-kinetic assessments and do not compare them with the characteristic dimensions of the space-charge layer (SCL) surrounding the probe (a.k.a charge sheath). Certainly, in this case, they very often go beyond the conditions which underlie the theory. The most acute problem of plasma diagnostics and determination of its parameters occurs in the case of 1–2 collisions of charged particles taking place in the probe SCL. In such diagnostics, questions arise about the way of determining the temperature of charged particles, about the mass of charged particles, the area of application of techniques and, certainly, about the SCL thickness.
