1. A short pulse dielectric wall accelerator comprising:
- a dielectric beam tube of length L surrounding an acceleration axis;
at least two pulse-forming lines transversely connected to the beam tube, each pulse-forming line having a switch connectable to a high voltage potential for propagating at least one electrical wavefront(s) therethrough independent of other pulse-forming lines to produce a short acceleration pulse of pulse width τ
along a corresponding short axial length δ
L of the beam tube; and
means for sequentially controlling the switches so that a traveling axial electric field is produced along the beam tube in synchronism with an axially traversing pulsed beam of charged particles to serially impart energy to said particles.

Abstract
A sequentially pulsed traveling wave compact accelerator having two or more pulse forming lines each with a switch for producing a short acceleration pulse along a short length of a beam tube, and a trigger mechanism for sequentially triggering the switches so that a traveling axial electric field is produced along the beam tube in synchronism with an axially traversing pulsed beam of charged particles to serially impart energy to the particle beam.
