Abstract (en)
[origin: EP0233083A2] An ion beam arrangement accepts a steady beam of ions from an ion source and forms a stream of ion bunches from it, so that the bunches or packets of ions can be subsequently utilised. The ion beam buncher consists of an electrode (2) to which a high frequency alternating potential (14) is applied to impart a velocity modulation to ions within the steady beam. This electrode is followed by a drift space (3) in which the velocity modulation results in the formation of the discrete bunches of ions, but without any overall increase in ion energy. These ion bunches can then be accelerated to high energy levels using a multistage alternating voltage linear accelerator (24, 25).
