Morphology
This is a straightforward noun–noun compound: a B1 learner who knows 'ion' (charged particle) and 'pump' (a device that moves substances) can infer it is a pump that works with or moves ions. The detailed technical mechanism (vacuum operation and adsorption) is specialized, but the core meaning is compositional and therefore transparent.
Etymology
The noun ion pump comes from how the device works: it turns gas atoms into charged particles called ions and then pulls them onto a metal surface so they stick. So the name ion pump helps you remember that it 'pumps' gas out of a chamber by trapping ions to create a strong 'vacuum'.
