Y. Okuno et al., EFFECTS OF DOWNSTREAM MAGNETIC-FIELD COLLIMATION ON ION BEHAVIOR IN ELECTRON-CYCLOTRON-RESONANCE MICROWAVE PLASMA, IEEE transactions on plasma science, 22(3), 1994, pp. 253-259
Effects of a magnetic field collimation on ion behavior in the downstr
eam region of an electron cyclotron resonance (ECR) plasma device are
clarified experimentally using a directional ion energy analyzer. The
drift energy and its spread of the ion beam observed in the downstream
region decrease and the beam temperature increases with the collimati
ng magnetic flux density. Then, the ion temperature measured perpendic
ular to the axis of the plasma stream slightly decreases. The ion beam
is found to be almost parallel to the magnetic field lines, that is,
the beam tends to be collimated.
