Figure 5.3 shows the linear response regimes in a lowfield tokamak fusion reactor. The boundaries between the regimes are calculated with . (See Table 5.1.) If we assume that and , which implies that (see Table 5.1), then it is clear from the figure that the relevant response regimes are the viscousinertial and the diffusiveresistive. Note that the respective inequalities, and , that must be satisfied in order to justify our neglect of the ion parallel dynamics in the layer equation are very easily satisfied in the viscousresistive and resistivediffusive regimes. (See Section 5.7 and Tables 5.1 and 5.2.)
Figure 5.4 shows the linear response regimes in a highfield tokamak fusion reactor. The boundaries between the regimes are calculated with . (See Table 5.1.)
