👉 The focal fluid, also known as the focal plasma or focused ion beam, is a highly concentrated and intense beam of charged particles, typically ions, that is used in various scientific and industrial applications. This fluid-like state is achieved by focusing a high-energy beam onto a small target area, creating a plasma with extremely high density and temperature. The focal fluid's unique properties, such as its ability to interact with materials at a microscopic level, make it invaluable in fields like materials science, nanotechnology, and medical applications, including precision cutting, surface modification, and targeted drug delivery.
