摘要

A MICROWAVE RESONANT SYSTEM WITH DUAL RESONANT FREQUENCY AND A CYCLOTRONFITTED WITH SUCH A SYSTEMABSTRACT OF THE DISCLOSUREThe invention discloses a resonant system for accelerating chargedparticles of the cyclotron type allowing this cyclotron to operate succes-sively at two resonant frequencies f1 and f2 = mf1 (m = 2 for example)without modification of the structure, this resonant system comprising asealed enclosure connected to ground and in which is disposed at least onehollow electrode or "Dee" having the shape of a sector, the enclosure and the"Dee", being associated with a resonant element formed from a tubularexternal conductor closed at one of its ends by a metal plate and whoseother end opens into the enclosure and, placed inside this external con-ductor, two internal conductors connected together, at one of their ends,by means of a connecting element determining with the external conductora capacity C variable in value, for adjusting the operating frequenciesf1 and f2 of the cyelotron and more particularly the ratio .
