Abstract
The derivation of a kinetic equation for a test-particle weakly interacting with an electrostatic plasma in thermal equilibrium, subject to a uniform external magnetic field, is considered. From the generalized master equation a Fokker-Planck-type equation (FPE) follows as a "markovian" approximation. Such an equation does not preserve the positivity of the distribution function. Applying an averaging technique developed in the theory of open systems, a correct FPE is derived.
