FIGURE 21.8.5.- Critical velocity
applied current for seven gases studied in the homopolar experiment.
(The slope of the Ar curve is related to the magnetic field's being
too weak to make the ion gyro-radii small enough). The theoretical
vcrit, for each
gas, as calculated from eq. (216.1), is indicated on the ordinate.
