MOP261	A Test Facility for MEIC ERL Circulator Ring Based Electron Cooler Design	electron, FEL, cathode, kicker	219

	Funding: * Supported by the U.S. Department of Energy, Office of Nuclear Physics, under Contract No. DE-AC05-06OR23177 and DE-AC02-06CH11357. An electron cooling facility which is capable to deliver a beam with energy up to 55 MeV and average current up to 1.5 A at a high bunch repetition rate up to 750 MHz is required for MEIC. The present cooler design concept is based on a magnetized photo-cathode SRF gun, an SRF ERL and a compact circulator ring. In this paper, we present a proposal of a test facility utilizing the JLab FEL ERL for a technology demonstration of this cooler design concept. Beam studies will be performed and supporting technologies will also be developed in this test facility

THO3B02	SRF Technology Challenge and Development	cavity, linac, HOM, ion	536
	A. Facco INFN/LNL, Legnaro (PD), Italy A. Facco FRIB, East Lansing, USA
	SRF technology in particle accelerators is in continuous evolution, providing a large variety of high gradient- low loss resonators with large apertures, suitable for many different beam current and energy regimes. Recent development was aiming not only at highest gradient and Q but also at improving field quality, reliability and cost reduction for large production. The SRF R&D effort, once concentrated mostly in the high energy electron machines, is increasingly focused to heavy ion linacs, energy recovery linacs and also to cavities for special applications. A concise overview of the present state of the art will be given.

THO3B03	SRF Cavity Research for Project X	cavity, linac, cryomodule, proton	541
	R.D. Kephart Fermilab, Batavia, USA
	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.
