The History and Importance of the Vacuum Tube - ThoughtCo
2019年2月3日 · A vacuum tube, also called an electron tube, is a sealed-glass or metal-ceramic enclosure used in electronic circuitry to control the flow of electrons between the metal electrodes sealed inside the tubes.
What is vacuum tube and how does it work? - Physics Network
2023年5月22日 · A vacuum tube consists of two or more electrodes in a vacuum inside an airtight envelope. Most tubes have glass envelopes with a glass-to-metal seal based on kovar sealable borosilicate glasses, though ceramic and metal envelopes (atop insulating bases) have …
Electron tube | Vacuum Tubes, Cathode Rays, & Applications
An electron tube has two or more electrodes separated either by vacuum (in a vacuum tube) or by ionized gas at low pressure (in a gas tube). Its operation depends on the generation and transfer of electrons through the tube from one electrode to another.

How Vacuum Tubes Work
All modern vacuum tubes are based on the concept of the Audion--a heated "cathode" boils off electrons into a vacuum; they pass through a grid (or many grids), which control the electron current; the electrons then strike the anode (plate) and are absorbed.
