The Fermilab High Intensity Neutrino Source program has built and commissioned a pulsed 325 MHz RFQ. The RFQ has successfully accelerated a proton beam at the design RF power. Experiences encountered during RFQ conditioning, including the symptoms and cause of a run-away detuning problem, and the first beam results are reported.

The intensity frontier, having been identified as one leg of the future of particle physics, can be meet by the development of a multi-GeV high-intensity linac. In order to address the low-energy needs of such an accelerator, Fermilab started the High Intensity Neutrino Source (HINS) project. HINS is a research project to address accelerator physics and technology questions for a new concept, low-energy, high-intensity, long pulse H- superconducting linac. The development of such an accelerator puts strict requirements on beam diagnostics. This paper will present beam measurement results of the HINS ion source and 2.5 MeV RFQ as well as discuss the role of HINS as a test facility for the development of future beam diagnostic instrumentation required for the intensity frontier.

A multi-MW proton facility, Project X has been proposed and currently under development at Fermilab. Project X is critical for future development of accelerator complex for future high energy physics programs in the US. In collaboration with Fermilab, LBNL is actively involved in the development and design studies of the front-end system for Project X. The front-end system would consist of H- ion source(s), low-energy beam transport (LEBT), normal conducting CW Radio-Frequency-Quadrupole (RFQ) accelerator(s), medium-energy beam transport (MEBT), beam chopper(s) and normal conducting CW rebuncher cavities. We will review and present R&D programs and recent study progress on the front-end system of Project X. These studies may include beam dynamics simulations and concepts for LEBT, RFQ, MEBT and narrow band chopper, and preliminary conceptual designs of normal conducting CW RFQ(s) and rebuncher cavities.

A new superconducting RF cavity test facility has been commissioned at Fermilab in conjunction with first tests of a 325 MHz, β = 0.22 superconducting single-spoke cavity dressed with a helium jacket and prototype tuner. The facility is described and results of full gradient, CW cavity tests with a high Qext drive coupler are reported. Sensitivities to Q disease and externally applied magnetic fields were investigated. Results are compared to bare cavity results obtained prior to hydrogen degassing and welding into the helium jacket.
