What are Particle Accelerators?
Particle accelerators are complex machines that use electromagnetic fields to propel charged particles, such as electrons or protons, to high speeds and contain them in well-defined beams. These machines play a crucial role in various fields including particle physics, materials science, and medical applications.
How do Particle Accelerators Function?
Particle accelerators function by employing electric fields to accelerate particles and magnetic fields to steer and focus them. There are different types of accelerators, such as
linear accelerators (linacs) and circular accelerators, like the
Large Hadron Collider (LHC). These machines can achieve particle speeds close to the speed of light, which makes them extremely valuable for high-energy experiments and applications.
