Linear particle accelerator

A linear particle accelerator, or linac, is a machine that accelerates charged particles, like electrons or protons, along a straight path using oscillating electric fields. These fields give the particles energy in stages as they pass through a series of radiofrequency cavities. The more energy they gain, the faster they move. Once accelerated, the particles are directed toward a target for scientific research, medical treatments, or other applications. Essentially, a linac is a precise, high-energy tool that speeds up particles in a straight line to study their properties or use their energy effectively.
