Morphology
cathode-ray + tube
The phrase is compositionally transparent: it literally describes a tube that contains/produces a cathode ray (a beam emitted from a cathode). Although the term is technical and may be unfamiliar at B1, if a learner knows the constituents ('cathode', 'ray', 'tube') the overall meaning is directly derivable and not idiomatic.
Etymology
The name cathode-ray tube comes from a simple picture: inside a long tube a hot metal part called the cathode sends out tiny particles that travel like a ray to hit a glowing screen. That's why the old 'TVs and computer monitors' that made pictures this way are called cathode-ray tubes.
