This quantity defines the maximum value of a modification to the Coulomb collision operator known as the Coulomb logarithm.
This quantity defines the maximum value of a modification to the Coulomb collision operator known as the Coulomb logarithm. The product of this quantity with the wave vector controls the degree of energy transfer between resonant particles and a propagating wave. This value can be obtained by considering a quasi-neutral Maxwell-Boltzmann system, solving its Poisson equation, and identifying this quantity with the characteristic length scale of the resultant exponential of minus the distance. This number is proportional to the square root of temperature over mass times the inverse of the plasma frequency, and its cube times the density gives the typical number of particles within its namesake sphere called the plasma parameter. For 10 points, identify this characteristic parameter of a plasma which indicates the distance over which the Coulomb potential from a point charge is shielded in a plasma.
