The CRT (Cathode Ray Tube) depends on a stream of electrons. In order that the stream be able to do what it is designed to do, there must not be atoms in its way, otherwise, the stream would interact with those atoms. Thus, the CRT must be highly evacuated.

Should i wear a grounding strap when servicing a CRT monitor?
I would suggest not wearing one, because the CRT uses very high voltages which could potentially remain while you are servicing it. Grounding yourself will put you at a greater risk of serious shock. The parts in a CRT are generally not as likely to be static sensitive as many other electronic devices, so the need for a grounding strap is not as great. Also, before working with a CRT, do some research into other precautions you should take to avoid electric shock.
Working principle of cathode ray oscilloscope?
A scope is nothing else then a display instrument it will amplify and display a signal on a CRT for visual analysis
What are the 4 parts of a cathode ray tube?
four parts of CRO: 1-crt 2-horizontal section 3-vertical section 4-power supply
Working principle of dual trace oscilloscope?
Dual-trace operation allows you to view two independent signal sources as a dual display on a single CRT. This operation allows an accurate means of making amplitude, phase, time displacement, or frequency comparisons and measurements between two signals. A dual-trace oscilloscope should not be confused with a dual-beam oscilloscope. Dual-beam oscilloscopes produce two separate electron beams on a single scope, which can be individually or jointly controlled. Dual-trace refers to a single beam in a CRT that is shared by two channels.
What do you mean by dual channel of cathode ray oscilloscope?
An oscilloscope with 2 vertical inputs that are multiplexed to the CRT, either by chopping them together on every sweep or alternating between them on every other sweep. Some oscilloscopes also support a differential mode where the 2 inputs are subtracted to produce a single combined signal.
What kind of gas is inside tv picture tube?
There are two main types of lights that are typically tube shaped:"neon lights" - these use mixtures of noble gases (e.g. helium, neon, argon, krypton, xenon) to produce different colors. These are usually used for advertising signs for businesses.fluorescent lights or UV lights - these use mercury vapor to produce UV light (in fluorescent lights a thin coating of a fluorescent powder transforms the UV light to visible light).
Can the gas in a CRT monitor leak out and cause health problems?
No, this would be impossible. CRT's are vacuum tubes, as in all gas has been evacuated out of the tube so the electron gun can be fired. So there is no gas that can leave, and if there was a leak it would leak into the monitor and cause it not to work anymore.
Why do CRTs have a vacuum?
Cathode rays consist of electrons. In order to keep the electrons in a cathode ray from scattering due to collisions with air molecules, a CRT needs to be sufficiently evacuated of air.
Why is it important not to open a CRT monitor even when it is unplugged?
there are highly charged capacitors inside monitors that could shock you
