A bounce-averaged Monte Carlo pitch-angle scattering operator presented by Tolliver (Phys. Fluids 28, 1083 (1985)) is discussed and shown to follow directly from a bounce-averaged drift-kinetic equation of Connor and Cordey (Nucl. Fusion 14, 185 (1974)). This operator is used in a discrete mapping analysis of radial transport of test particles in a slightly rippled tokamak, illustrating time step restrictions for its validity. This treatment of collisions is different than that of Yushmanov (Nucl. Fusion 23, 1599 (1983)) but gives the same results for ripple transport.
