FIGURE 21.8.5.- Critical velocity vcrit versus 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. (From Angerth et al., 1962.)
