The cathode ray tube was not discovered it was invented by Ferdinand Braun
The cathode ray experiment helped discover electrons
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
Electrons.
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.

He executed the Cathode Ray Experiment (I think).
The cathode ray diagram is significant because it shows the path of electrons in a cathode ray tube. By understanding this diagram, scientists were able to discover the behavior of electrons, leading to advancements in technology like television and computer monitors.
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
Cathode Ray
Anode ray is positive and cathode ray is negative
Electrons.
Julius Plucker did not discover the electron. The electron was discovered by J.J. Thomson in 1897 through his experiments with cathode ray tubes.
