MAGNETIC GROUPING SYSTEM FOR LOADED PARTICLES WITHIN A PULSED BEAM

摘要

P Magnetic system making it possible to obtain, from a pulsed beam of electrons delivering packets of electrons, of density do, a pulsed beam formed of packets of electrons of density k do, this result being obtained by converting the variation in momentum of momentum of the electrons emitted during the DELTA t time of a pulse, into a variation in the length of the trajectories of these electrons, this resulting in a grouping of electrons within the packets. This magnetic system comprises an electromagnet of several pole pieces A, B, D delimiting a succession of air gaps in which are created, by means of at least one annular coil arranged in these air gaps, magnetic fields of different values. /P P Application: irradiation of a target using a short pulse beam, delivering high density accelerated electron packets. /P
