The density response function for streaming ions in homogeneous, parallel electric and magnetic fields is derived self‐consistently from kinetic theory. Ion‐neutral collisions are treated with the Bhatnagar‐Gross‐Krook collision operator assuming a constant ion‐neutral collision frequency. The result accounts for the non‐Maxwellian distribution function of the ions and is valid in the full range from weak to strong magnetization. It provides the basis for various linear response calculations in the context of magnetized complex plasmas, where streaming ions interact with highly charged dust particles under the influence of a strong external magnetic field.
