摘要：
The experience gained in using an array of cylindrical Langmuir probes as a perturbing body for plasma-jet diagnostics is described. The plasma potential on a part of the probe is determined from the ion-scattering minimum at that part. The potential values thus obtained are compared with the results of an analysis of the probe characteristics. The conditions for applicability of the method are discussed. A density marker is created by applying a voltage pulse with a duration of 30 ns to the probes, and time-of-flight probing of the plasma jet is performed.
