Morphology
The proper name 'Wilson' is eponymous and does not contribute semantic content a learner can use; 'cloud' + 'chamber' transparently suggests an enclosed space with vapour or clouds, so a B1 learner would likely infer it is some kind of device involving vapour. However, the specialized function (making charged particle tracks visible) is technical and not directly derivable from the constituents, so the expression is only partially predictable without domain knowledge.
Etymology
Wilson cloud chamber is named after the scientist Wilson and describes a small chamber where a thin cloud or 'mist' forms. When tiny charged 'particles' move through the mist they make visible 'trails', so the device lets you see the 'paths' of those particles.
