Studies of plasma parameters in low pressure discharge initiated in coaxial waveguide by microwave stochastic radiation

摘要

It is shown, to create an effective discharge, which initiated by means of radiation with a jumping along phase,udexpediently to operate only at pressures nearby to the left part of breakdown curve. Because at the increasing ofudpressure the losses of energy are increased on elastic and non-elastic collisions, that reduces efficiency of discharge.udAuthors in first measured a plasma density in low pressure discharge initiated by a microwave radiation with theudjumps of phase with help developing the original technique of the use the double probes of Langmuir, separateudsource of direct-current, high-frequency transformers, digital oscilloscope and least-squares method for treatment ofudsignals, using the special type of function of regression.
