The cathode ray tube was invented in 1897 by Ferdinand Braun.
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
The cathode ray is just a beam of electrons. The color of the fluorescence depends on the substance in the target.
The Cathode Ray Tube is called CRT, but I don't know of any "modern day" name. I know it was discovered by J.J. Thomson, who discovered electrons through the Cathode Ray Tube.
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.

Anode ray is positive and cathode ray is negative
Electrons.
The cathode "ray' must have been made up of negatively charged particles, now called electrons.

The property shown by the phenomena is that the cathode ray is negatively charged. A cathode ray is also called an electron beam or an a-beam.
When a magnetic field is applied to a cathode ray, the cathode ray is deflected.
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
The cathode ray experiment helped discover electrons
