What is vacuum technology?

Vacuum technology refers to the techniques and equipment used to create, maintain, and measure vacuum, which is a space devoid of matter. It's commonly used in various applications, including scientific research (e.g., particle accelerators, surface science), industrial processes (e.g., semiconductor manufacturing, vacuum coating, freeze-drying), and everyday devices (e.g., vacuum cleaners, incandescent light bulbs). Vacuum is created by removing air and other gases from a sealed space, typically using vacuum pumps.
