Abstract From the Canadian patent

This invention relates to an accelerator for charged particles which comprises a vessel adapted to enclose a stream of charged particles along a preselected track. A magnetic field travelling in a preselected direction relative to each point of the track with the magnetic flux vector of the field transverse to the track at all points is generated thereby, setting the particles in motion along the track with a velocity which has a predetermined relation to the velocity of the travelling field. The invention utilizes in a particle accel-, erator, specific dynamic effects caused by the unidirectional entrainment of both positively and negatively charged particles of a plasma by a travelling …
