AB A kinetic electron model and a fluid ion model are combined to describe the 2D plasma expansion in an axisymmetric magnetic nozzle in the fully-magnetized, collisionless limit. Electrons can be separated into free, reflected, and doubly-trapped populations, and are seen to develop anisotropy and to cool down in a non-trivial way downstream. A polytropic electron model with same asymptotic electric potential value,  8, misses these kinetic aspects and fails to approximate the behavior of the electric potential and the average electron temperature. These differences are important in determining the performance of the device.
