El tubo de rayos catódicos ( TRC) o simplemente tubo catódico es una tecnología que permite visualizar imágenes mediante un haz de rayos catódicos constantemente dirigido contra una pantalla electroluminiscente. 1 La pantalla está hecha de vidrio y recubierta de fósforo y plomo; 2 el primero permite reproducir la imagen proveniente del haz d...
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen.
Un CRT es un tipo de dispositivo de visualización que produce imágenes mediante un haz de electrones que se proyecta sobre una pantalla recubierta de fósforo. El haz de electrones es generado por un cátodo caliente, que es un electrodo cargado negativamente situado en la parte posterior del tubo.
The cathode ray Tube (CRT) is the heart of the C.R.O. the CRT generates the electron beam, accelerates the beam, deflects the beam and also has a screen where beam becomes visible as a spot. The main parts of the CRT are: Electron Gun. Deflection system. Fluorescent screen.

2 de dic. de 2022 · The cathode ray tube (CRT) is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images. It modulates, accelerates, and deflects electron beam (s) onto the screen to create the images.
19 de may. de 2023 · 1. do you mean CRT as in the display (like an old TV)? There are a LOT of different kinds of "tubes" that use "cathode rays", and some may need a slight amount of gas for one reason or another, but mostly you'd like a really good vacuum. When you say "Why should there be...?" it suggests you heard or read somewhere that there "should" be.
