It is very interesting question.
We know that the cathode ray is a beam of electrons in a vacuum tube traveling from the negatively charged electrode (cathode) at one end to the positively charged electrode (anode) at the other, across a voltage difference between the electrodes. They are also called electron beams.
These rays are not the part pof light spectrum and doesn't contain photons. It does not produce light of there own......
Instead, they produced a colorful glow discharge (as in a modern neon light), caused when the electrons or ions struck gas atoms, exciting their orbital electrons to higher energy levels. The electrons released this energy as light.

Answer:
The anode (positive terminal) is in the base of the tube at bottom. Cathode rays travel from the cathode at the rear of the tube, striking the glass front, making it glow green by fluorescence. A metal cross in the tube casts a shadow, demonstrating that the rays travel in straight lines.
