Particle beam technology involves the use of charged or neutral particles, such as electrons or ions, directed in a beam to interact with materials. This technology is commonly used in fields like medical treatment, where it can target cancer cells with precision, minimizing damage to surrounding healthy tissue. In addition to medical applications, particle beams are also utilized in materials science for analyzing the properties of materials and in accelerators for fundamental research in physics. The ability to manipulate particles at high speeds allows scientists to explore the structure of matter and the forces that govern the universe.
