GANIL RF Systems

Final studies on a model were made simultaneously for the three types of GANIL resonators : separated sector cyclotrons, injector cyclotron and buncher n° 13. These investigations have permitted complete definition of the main parameters of these resonators (size, tolerances, current and voltage distribution, losses, coupling and tuning). Mechanical studies for the three resonators are nearly finished. Technological studies on sliding contacts have been made at full current. Phase and amplitude regulation systems have also been tested. The values measured fully satisfy GANIL tolerances. Construction of the first two resonators of CSS, CO and buncher will start in July 1979. At the same time the prototype of a 100 kW RF transmitter has been satisfactorily tested and construction of the first three amplifiers will begin soon.
