No, but it is a direct predecessor. X-rays were accidentally discovered using a similar type of cathode ray tube by Röntgen.
You cannot see the rays themselves, but you can see their effect, such as fluorescence where they strike the glass or a target inside the tube.
It was crucial for experiments that led to the discovery of the electron, fundamentally changing our understanding of atomic structure.
