The reason is simply that when the charge comes around to where it started, which means that it is at the same potential; hence its kinetic energy cannot have changed. With static cavities, the charge would be slowed down by the fringing fields outside the cavities before it could be accelerated back to its original speed inside the cavity. So ideally (but not in real accelerators), the fields shouldn't cycle on until the charges are already inside | |
