Abstract:
Originally, Landau found a decay of oscillations in collisionless plasma, solving Vlasov equation with Laplace transform (1946). Later, Bohm and Gross pointed out that Landau damping results from energy transfer from the oscillating coherent field to its resonant particles (1949). The third point of view on the Landau damping was developed by van Kampen, who built a theory of eigenfunctions of the Vlasov equation (1955). In this talk, all the three approaches are discussed for longitudinal oscillations of a coasting beam.
