Claim:
1. A device for accelerating charged particles, the device comprising: a dielectric loaded accelerator for accelerating charged particles along a longitudinal axis of the accelerator and towards an outlet of the accelerator, said accelerator comprising; an elongated body made from a conductive material; and a dielectric material extending continuously along a length of the accelerator and extending radially inward from an interior surface of the elongated body to a central cavity surrounding said longitudinal axis; said central cavity being uniform in diameter throughout its length; and said dielectric material and elongated body being varied in outer diameter along said length of the accelerator such that an electromagnetic mode of the accelerator has a phase velocity that (i) increases towards the outlet of the accelerator and (ii) matches a velocity of the charged particles accelerated along the longitudinal axis.
