High power of RF energy fed into single cavities is needed for state-of-the-art particle accelerator facilities and their upgrades. Delivering this from a single tube-based source, such as klystrons, tetrodes or IOTs, is generally possible but bears the risk of a single point of failure. Additionally, tube technology is obsolete and availability on the market continuously decreasing....
The Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab initially delivered a 4 GeV electron beam simultaneously to three experimental halls. Through two major energy upgrades, it now delivers an 11 GeV beam to three halls and a 12 GeV beam to a fourth hall. These upgrades necessitated modifications to the Separation System, including increasing RF power, reconfiguring the...
The Paul Scherrer Institute (PSI) is upgrading its High Intensity Proton Accelerator (HIPA) facility to enhance beam power and improve reliability. As part of this effort, the upgrade of the RF system for the Injector 2 cyclotron began several years ago. To increase the energy gain per turn, the two 150 MHz flattop cavities were replaced by higher-voltage 50 MHz aluminum cavities. New...
The Spallation Neutron Source (SNS) facility at Oak Ridge National Laboratory (ORNL) in Oak Ridge, TN, USA completed the proton power upgrade (PPU) project in 2024 and is operating with 1.7 MW of beam power on target (August 2024). The RF-driven SNS Ion Source produces a ~ 1 ms long H- beam pulse at a 60 Hz pulse repetition rate. The SNS Ion Source utilizes a dual RF system to ignite and...
