CoulombLnFaktor
CoulombLnFaktor, also known as the Coulomb logarithm, is a fundamental concept in plasma physics and astrophysics, used to describe the strength of interactions between charged particles in a plasma. It is named after Charles-Augustin de Coulomb, the French physicist who formulated the law of electrostatics. The Coulomb logarithm, often denoted as lnΛ, is a measure of the average number of particles a test particle can interact with over a given distance.
The Coulomb logarithm is defined as the natural logarithm of the ratio of the maximum impact parameter
The value of lnΛ depends on the plasma parameters, such as the temperature, density, and composition. In
The Coulomb logarithm is crucial in various plasma processes, including collisional energy transfer, thermal conduction, and
Despite its importance, the Coulomb logarithm is not a constant and can vary significantly within a plasma.
