Figure T7.1 is a schematic diagram of the principal elements of a cathode-ray tube. The interior of the tube is a very good vacuum, with a pressure of around; 0.01 Pa (10−7 atm) or less. At any greater pressure, collisions of electrons with air molecules would scatter the electron beam excessively.

As you can see in the below drawing, there's not a whole lot to a basic cathode ray tube. ... However, in this diagram you can see no way to "steer" the beam -- the beam will always land in a tiny dot right in the center of the screen.

The CRT is a large, cone-shaped glass tube that site on it's side, ... It is not shown in the diagram, but a dense, series of coiled wires, called a "deflection yoke", are place along the sloped sides of the CRT, and scanning signals are sent through these wires, creating a magnetic field to bend the beam left, right, up,

The diagram below shows the main parts of the type of c.r.t. used in oscilloscopes. ... The front of the tube consists of a screen coated with a fluorescent material. This material gives out light when it is hit by fast moving electrons so we see a spot of light at the point where the electrons hit the screen.
