Description
PSI's proton accelerator facility currently produces a 1.2 MW beam. The extraction energy of the Ring cyclotron is 590 MeV and the beam current is 2 mA. It is planned to increase the beam current to 3 mA requiring several upgrades of the RF-system.
The replacement of the 4 aluminum cavities in the ring cyclotron by copper cavities is a milestone in this program. The last 2 cavities have been installed recently during shutdown 2008.
Beam dynamics calculations show that the flattop cavity in the ring cyclotron can eventually be replaced by introducing a buncher in the beamline between injector 2 and the ring. This buncher will be driven by a 506 MHz / 30 kW amplifier. First test results of this system will be presented.
At the Injector 2 cyclotron it is planned to replace the flattop cavities (150 MHz) by accelerating cavities (50 MHz). This will allow to increase the turn separation at extraction with lower beam losses. Due to the fact of changing the resonance frequency of the cavities new amplifier chains have to be built. An overview of the new system will be given.
