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.
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 tube was invented in 1897 by Ferdinand Braun.
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.
Low pressure inside a cathode ray tube? How about nopressure inside the tube! In a cathode ray tube, the "cathode ray" is an electron beam that is used to paint a "picture" on the phosphor coating on the inside of the tube. (We look at the "picture" from the other side of the glass on which the coating is laid down - the outside.) An electron is a lightweight little dude. It weighs about 1/1836th as much as a single proton, so anything, any gas atoms that are in the flight path of an electron will cause it to scatter. That means we need to pump all the air out of the inside of the tube. After we remove all we can, we fire a "getter" (a chemical coated onto a small area inside the tube) which will bind any remaining gas molecules left inside the tube to complete the evacuation process. No more pesky atoms to get in the path of the electron beam and scatter it all over the place.
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.

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.

It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
The electron was discovered by using cathode ray tubes. When it was discovered that the cathode ray diverted away from the negative end of a magnet to the positive end, it revealed that there was a negative particle present in the ray.
the deflection of an electron beam in a cathode ray tube by electric and magnetic feilds.
This refers to when electromagnets were used rather than electrostatics to direct electron flow in a CRT (Cathode Ray Tube). Coils would be placed around the neck of the tube to influence the deflection of the cathode ray (electron flow) to the screen.

The solution to a cathode ray tube physics problem involving electron acceleration and deflection is to apply the principles of electromagnetism and the laws of motion to calculate the trajectory of the electrons as they are accelerated and deflected by electric and magnetic fields within the tube. By solving the relevant equations, one can determine the path of the electrons and predict their behavior within the cathode ray tube.
