ELECTRON LINEAR-ACCELERATOR USING PHASED MULTI-ELECTROMAGNETIC-WAVE BEAMS

The motion of charged particles in a multi-electromagnetic-wave beam ( multi-EM beam) system has been investigated numerically. This system c onsists of many plane electromagnetic-wave beams propagating parallel to each other, but the phase is delayed successively from one beam to the next. The resultant electromagnetic field seems to be a slow wave which can interact with the particle beam. When a static magnetic held is applied parallel to the fluctuating magnetic field of the wave, it is concluded from numerical calculations that the charged particles i njected in this scheme are trapped in the apparent wave and accelerate d stably to high energy, close to the speed of light.
