Answers
Explanation:
The cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen.[2] The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer.
Answer:
Cathode rays (electron beam or e-beam) are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply)
Explanation:
The General High Voltage CRT Power Supply, CR25 series, is a bespoke cathode ray tube power supply unit with auxiliaries that provide a highly regulated output for many of the electrodes in a high-resolution shadow mask colour Cathode Ray Tube (CRT). The product is rated at 30kV and 30W. The DC input voltage is 38V (nominal) and the anode output voltage is adjustable between 20kV and 28kV. The output regulator circuits are designed to provide a power supply which has good static and dynamic regulation, combined with very low ripple, ensuring a display that remains stable and sharp over a wide range of brightness modulation. As well as the anode supply, rated at 30 Watts, the module generates adjustable focus G1 and G2 outputs. Current limiting circuits are fitted to protect the outputs against overloads and short circuits. All outputs are individually regulated. Ruggedised military type specification available.
