Experience with Recently Commissioned High Power Proton Accelerators and Prospects for the Future

  Two major high power proton accelerator facilities have recently been commissioned and are now in the early operations phase. The Japan Proton Accelerator Research Complex (J-PARC) at JAEA, Tokai, Japan completed commissioning in 2009 and is now operating at beam power as high as 300 kW for the neutron scattering program, while providing beams also for the neutrino program. The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory is now operating at 1 MW beam power on target for its neutron scattering program. These facilities incorporate modern high-power accelerator design principles and their experience serves as a valuable stepping-stone to the high-power accelerators of the future, namely Project-X, the European Spallation Source, and accelerators for nuclear energy. Experience with commissioning and initial operation of these new facilities will be described and prospects for the future will be summarized.

The Facility for Rare Isotope Beams (FRIB) will be a world-leading, DOE national users facility for the study of nuclear structure, reactions and astrophysics on the campus of Michigan State University. A superconducting, heavy-ion, driver linac will be used to provide stable beams of >200 MeV/u at beam powers up to 400 kW (~650 electrical micro-amps for uranium) that will be used to produce rare isotopes by in flight fragment separation. The selected rare isotopes will be used at velocity (~0.5 c), stopped, or reaccelerated. FRIB is a challenging technical project. An overview of the project, project challenges, and mitigating strategies will be presented.

FROBN3 Project X - New Multi Megawatt Proton Source at Fermilab 2566
 
  • S. Nagaitsev
    Fermilab, Batavia, USA
 
  Fermilab plans to replace its present injection complex consisting of a pulsed linac and 15 Hz Booster with a new injection complex based on a superconducting CW linac. This new proton source should boost the power of the Main Injector to 2 MW and enable new experiments with a high power proton beam in the range of 1-3 GeV. The speaker will present recent developments from the Fermilab Project X R&D.

FROBN4 Commissioning of the 20MV Superconducting Linac Upgrade at TRIUMF 2570
 
  • M. Marchetto
    TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada
 
  The Phase II upgrade of the ISAC-II Superconducting Heavy Ion Linac involves the addition of twenty quarter-wave bulk niobium resonators housed in three cryomodules. This addition brings the total installed accelerating voltage from 20MV to 40MV. The cavities are produced in Canadian industry with cavity testing and cryomodule assembly at TRIUMF. The speaker will discuss commissioning of, and operations with, this major upgrade, which commenced in April 2010.
