  The intensity frontier research is an important part of modern elementary particle physics. It uses proton beams to create secondary beams consisting of, but not necessary limited to, neutrinos, muons, kaons and neutrons. Deferent experiments require different time structure of proton beams but all of them require the beam power of about or exceeding 1 MW. In addition, powerful proton linacs can find an application in accelerator driven nuclear reactors and transmutation of radioactive waste. Recent advances in the superconducting RF technology make a multi-MW power level economically acceptable. This paper discusses main physics and technical limitations determining ultimate parameters of such accelerators, their structure and performance.

The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) is currently constructing its new rare isotope reaccelerator facility: ReA3, which will provide unique low-energy rare isotope beams by stopping fast rare isotopes in gas stopping systems, boosting the charge state in an Electron Beam Ion Trap (EBIT) and reaccelerating them in a superconducting linac. The rare isotope beams will be producted intially by Coupled Cyclotron Facility (CCF) at NSCL and later by Facility for Rare Isotope Beams (FRIB), currently being designed and constructed at MSU. The accelerator system consists of a Low Energy Beam Transport (LEBT), a room temperature RFQ and a linac utilizing superconducting QWRs. An achromatic High Energy Beam Transport (HEBT) will deliver the reaccelerated beams to the mutiple target stations. Beams from ReA3 will range from 3 MeV/u for heavy nuclei such as uranium to about 6 MeV/u for ions with A<50. The commissioning of the EBIT, RFQ and two cryomodules of the linac is currently underway. The ReA3 accelerator system design and status of commissioning will be presented.

THO3B03 SRF Cavity Research for Project X cavity, linac, SRF, proton 541

  Project X is a new SRF linac based multi-MW class proton source proposed for construction at Fermilab. It consists of a 3 MW, 1 mA CW H SRF linac that feeds an intensity frontier Physics program and a 3-8 GeV pulsed linac that accelerates ~5% of the output of the CW linac to 8 GeV for injection into the Fermilab Main Injector synchrotron resulting in an additional 2 MW of beam power at 60-120 GeV in support of a world class long baseline neutrino program. The project has chosen operating frequencies that are sub-harmonics of 1.3 GHz and is developing 6 separate cavity designs for acceleration of H particles with various velocities. An R&D program is in progress to develop these cavities; the associated cryomodules; and the required fabrication and test infrastructure. A status and progress report on this R&D program will be presented.
