Morphology
This is a straightforward noun–noun compound where 'counter' (a device that counts) modifies 'tube' (a hollow cylinder), so a B1 learner who knows both constituents can infer 'a tube that counts' — i.e. a tube used to count/detect events such as radiation. The composition follows a common, cross-linguistic compounding pattern (function + object), so the meaning is compositional and immediately derivable from the parts.
Etymology
The name counter tube comes from a simple picture: a glass tube that works as a counter, giving a small signal each time a particle passes through. That's why the name means a 'tube' that 'detects' and 'counts' radiation particles.
