Oscillation characteristics of discharges generated in magnetron structural devices.
Noboru Tanizuka · Shinku · 1986
An experimental study of oscillation characteristics of a static E×B (B : weak) discharge is given.The detection of a low-frequency (a level of one megahertz) monochromatic spectrum is closely related to a reciprocating motion of ions resonant with a superposed oscillation potential in an electric potential through formed across the magnetic field.The detection of a continuum spectrum below a few megahertz, which is characterized by the power spectrum P∝f-α (α : a constant, 4_??_α_??_5) and is given alternative with the monochromatic, is closely related to the change or the instability of the electric potential.
