- Specialized
- His theory of energy loss of charged particles in their passage through matter became the basis for extracting quantitative data from cloud chamber tracks and later, nuclear emulsions.
Examples
-

Known to physicists for almost the entirety of this century, the cloud chamber, with its distinct tracks tracing the paths of particles, made the abstractions of atomic and nuclear physics appear as visually evident as skywriting.
Academic text (1997) -
In a cloud chamber, particles leave visible trails that help scientists trace their paths.

Morphology
The compound is transparently built from 'cloud' + 'chamber', so a B1 learner who knows both words would infer it refers to an enclosed space involving clouds or vapor. However, the specific technical function — detecting high-energy particle tracks — is specialized and not predictable from the constituents alone, so the relation is only partially clear to learners.
Etymology
The name cloud chamber comes from the way the device looks: inside a small chamber, drops of vapor form thin white cloud lines where fast particles pass, making visible 'trails'. That's why the name means a device that 'detects' and shows the 'paths' of invisible particles.
