III. General characteristics of accelerators

Obj. 1

Identify the general

characteristics of accelerators.

Accelerators are devices that increase the speed

and thus the energy of charged particles.

A. Accelerator energy

Accelerators are normally rated by the maximum

energy to which the particles are accelerated.

The energy imparted to the charged particles is

determined by the potential difference measured

in volts (V) in the electrical field. At all but the

smallest accelerators, the acceleration is

accomplished by directing the charged particles

repeatedly through regions containing

radiofrequency electromagnetic fields.
