The electron beam is typically created using a high-energy electron beam accelerator, called a linear accelerator, sometimes abbreviated to linac. The longer a linac is, the higher the energy of the particles it can produce. The longest linac in the world is the Stanford Linear Accelerator, SLAC, which is 3 km (1.9 mi) long. 3 Parts of First, the accelerator uses electricity to "push" the charged particles along a path, making them go faster and faster. A particle accelerator is a machine that propels charged particles to very high speed and energies by using electromagnetic fields. Since that time, a sizable number of linear accelerators, also called linacs, have come into operation, both for electron and proton acceleration, as well as several heavy .
