A qualitative approach to explaining the mechanism of ion acceleration by an electron beam in plasma
Acceleration of ions in a vacuum discharge, accompanied by electron beam, is known. Recently this effect is probably observed in connection with investigation of a high current non-sputtering magnetron discharge. In the present note a qualitative approach in the framework of a one-dimensional mode...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Acceleration of ions in a vacuum discharge, accompanied by electron beam, is known. Recently this effect is
probably observed in connection with investigation of a high current non-sputtering magnetron discharge. In the
present note a qualitative approach in the framework of a one-dimensional model of this phenomenon is considered
without taking into account collisions. A high-current electron beam, when injected into the plasma, generates
power oscillations. With the loss of energy for the excitation of oscillations and in the process of increasing the
current of the electron beam, a virtual cathode appears. The ions are captured by the virtual cathode and accelerated
in the direction of the electron collector. |
