The IPHI (High Intensity Proton Injector) is a facility developed at CEA/Saclay in collaboration with CERN and IN2P3. The final step of this Low Energy accelerator prototype designed to accelerate beams up to 100 mA with energy up to 3 MeV is in progress. An overview of the main components is given, the RF source is described and last RF measurements are shown.

The original vacuum-tube-based rf power amplifiers (four online, two spare) that drove the four rebunching cavities on the Spallation Neutron Source (SNS) Medium Energy Beam Transport (MEBT) structure have been replaced with commercially available 25-kW solid state amplifiers (4 online, one spare). A 4+1 switch matrix permits remote switching of the spare amplifier into any one of the four...

European Spallation Source (ESS) is one of the world’s most powerful neutron sources. The ESS linac will accelerate 50mA of protons to 2.5GeV in 2.86ms long pulses at a repetition rate of 14 Hz. It produces beam with 5MW average power and 125MW peak power. There are 36 superconducting spoke resonators, which provide a power of 0.5MW to the beam.

The Advanced Photon Source (APS) booster and storage ring rf systems utilize 352-MHz, 1.2 MW klystrons as final rf amplifier devices. After seventeen years of APS operation, optimized system designs and detailed preventative maintenance activities have resulted in rf system reliability statistics that have exceeded the wildest expectations hoped for at the start of APS operations. How we...

The European Spallation Source Linac reaches an energy of 2.5GeV within 350 meters. The linac delivers an average power of 5 MW with a 4% duty factor (2.9 mSec pulse at a rate of 14Hz). The peak power of the linac is over 123 MW. This averages to a peak power density that must be supplied to the beam of over 350kW/meter. Because of the large power density, 98% of the linac consists of...

At PSI, protons are accelerated up to an energy of 590 MeV by two separated sector cyclotrons, the Injector 2 and the Ring. Since 2008 the Ring cyclotron is running with 4 copper cavities. By increasing the cavity voltage to 850 kVp the number of turns was reduced and the beam current is increased up to 2.4 mA, which results in a beam power of 1.4 MW.
In 2010 the regular operation suffered...
