Electron linear accelerator based onVp×Bacceleration scheme

A new type of electron linear accelerator realized in a vacuum system, based on the ${\mathbf{V}}_{\mathit{p}}$×B acceleration scheme observed originally in plasma, has been demonstrated. The present system has a static magnetic field applied vertically to the wave propagation direction, and the particles are accelerated along the wave front at constant phase with respect to the wave. In this scheme, a greater acceleration rate than that of conventional linear accelerators has been observed. The acceleration rate is also larger than that expected from the simple theoretical model presented so far.
