Abstract
In this chapter we study the guiding center orbits in equilibrium plasmas using the Hamiltonian equations for the guiding-center motion given in the previous chapter. Particularly, we define drift surfaces, and study their structures for passing and trapped particles, estimate their widths.

Notes
- 1.
As we will see in Sect. 5.2.1 the angle variable can be taken as the parameter \(\vartheta \).
- 2.
Usually the term “bounce” is applied for the trapped orbits, while “transit” for the passing ones.
- 3.
In general, as was shown by Perkins and Bellan (2010) in the systems containing one fast-oscillating coordinate the net displacement other coordinate over single period is given by the differentiation of the action variable associated oscillating coordinate.
