Cathode rays are a beam of electrons emerging from the cathode (the negative terminal) within an electron tube. Electrons are actual particles with mass and charge.

X-rays are not charged particles but massless electromagnetic radiation. X-rays can be produced by the deceleration of electrons, by atomic electrons quantum jumping to a lower energy state, from atomic nuclei via radioactivity, and other processes.
