Abstract
The invention discloses a resonant system for accelerating charged particles of the cyclotron type allowing this cyclotron to operate successively at two resonant frequencies f.sub.1 and f.sub.2 =mf.sub.1 (m=2 for example) without modification of the structure, this resonant system comprising a sealed enclosure connected to ground and in which is disposed at least one hollow electrode or "Dee" having the shape of a sector, the enclosure and the "Dee" being associated with a resonant element formed from a tubular external conductor closed at one of its ends by a metal plate and whose other end opens into the enclosure and, placed inside this external conductor, two internal conductors connected together, at one of their ends, by means of a connecting element determining with the external conductor a capacity C variable in value, for adjusting the operating frequencies f.sub.1 and f.sub.2 of the cyclotron and more particularly the ratio f.sub.1 /f.sub.2.
