The discussion centers on the design of electron guns, specifically the tilting of the plate in relation to the electron path. The tilt allows the electron beam to effectively scan the entire screen, rather than being confined to a small central area. Participants reference the differences between electron guns and X-ray tubes, and highlight the role of magnetic deflection in CRT TV tubes. The complexity of electron optics is acknowledged, emphasizing that design variations depend on specific applications, such as high-frequency oscilloscope tubes.
PREREQUISITESEngineers, physicists, and students interested in electron gun technology, CRT design, and electron optics will benefit from this discussion.
Tilted plate in an electron gun? Did you mean an X-ray tube?SWKatzen said:
Can you link to some pages that show this? That would help us out. Thanks.SWKatzen said:
So that the electron beam will scan the whole screen rather than just a small region in the central areaSWKatzen said:
In a CRT TV tube, the deflection is magnetic and comes after the beam leaves the gun. We'd really need to see the particular gun that you are discussing.davenn said:

Yeah, I thought you would but did the OP know? It could be that the throat of the gun is flared because there is a finite magnetic deflection, even that far back.davenn said:
