krook_collisions

Add Krook collision operator for electrons

Note that this function operates on a single point in r, so pdf_out, pdf_in, dens_in, upar_in, upar_ion_in, and vth_in should have no r-dimension.

get_collision_frequency_ee(collisions, n, vthe)

Calculate the electron-electron collision frequency, depending on the settings/parameters in collisions, for the given density n and electron thermal speed vthe.

n and vthe may be scalars or arrays, but should have shapes that can be broadcasted together.

get_collision_frequency_ei(collisions, n, vthe)

Calculate the electron-electron collision frequency, depending on the settings/parameters in collisions, for the given density n and electron thermal speed vthe.

n and vthe may be scalars or arrays, but should have shapes that can be broadcasted together.

get_collision_frequency_ii(collisions, n, vth)

Calculate the ion-ion collision frequency, depending on the settings/parameters in collisions, for the given density n and thermal speed vth.

n and vth may be scalars or arrays, but should have shapes that can be broadcasted together.
