The Coherent Electron Cooling Proof of Principle (CeC PoP) system is being installed in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. It will demonstrate the ability of relativistic electrons to cool a single bunch of heavy ions in RHIC. This technique may increase the beam luminosity by as much as tenfold. Within the scope of this experiment, a 112 MHz 2 MeV Superconducting Radio Frequency (SRF) electron gun coupled with a cathode stalk mechanism, two normal conducting 500 MHz single-cell bunching cavities, a 704 MHz 20 MeV 5-cell SRF cavity and a helical undulator will be used. In this paper, we provide an overview of the engineering design for this project, test results and discuss project status and plansd.

An ampere class 20 MeV superconducting Energy Recovery Linac (ERL) is presently under commissioning at Brookhaven National Laboratory (BNL). This facility enables testing of concepts relevant for high-energy coherent electron cooling, electron-ion colliders, and high repetition rate Free-Electron Lasers. The ERL will be capable of providing electron beams with sufficient quality to produce high repetition rate THz and X-ray radiation. When completed the SRF photoinjector will provide 2 MeV energy and 300 mA average beam current. The injector for the R&D ERL was installed in 2012, this includes a 704MHz SRF gun* with multi-alkali photocathode, cryo-system upgrade and a novel emittance preservation zigzag-like low energy merger system. We describe the design and major components of the R&D ERL injector then report the first experimental results and experiences learned in the first stage of beam commissioning of the BNL R&D ERL. * Wencan Xu et al., “Commissioning SRF gun for the R&D ERL at BNL”, IPAC2013 proceedings, WEPWO085.

TUPRO076	Initial Experimental Analysis into the eRHIC Polarized Electron Beam Transport System	1217
	C. Yeckel, E. Dobrin, P. Holen, R.C. Miller, M. Stangenes, K.A. Thompson, L.W. Thompson Stangenes Industries, Palo Alto, California, USA I. Ben-Zvi, R.F. Lambiase, J. Skaritka, E. Wang BNL, Upton, Long Island, New York, USA
	Stangenes Industries is working closely with Brookhaven National Lab in the United States to develop the eRHIC future ion collider. The collider requires a polarized electron source with high average current, short bunch length and small emittance. An array of photocathodes with their beams funneled into a common trajectory is utilized to achieve the required beam current and cathode lifetime. Stangenes Industries is charged with delivering the prototype injector for preliminary beam studies that will lead to full implementation by 2020. This study focuses on the development of the of beam transport system extending from cathode to beam dump. A majority of the complexity involves the so called "combiner magnet" that acts as a high frequency-rotating dipole to bend each beam into the final common trajectory. Preliminary experiments into the feasibility of such a system are analyzed.

WEOAB01	The Commissioning of the Laser Ion Source for RHIC-EBIS	1890

	Funding: Work supported by NASA and Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy A new laser ion source (LIS) for low charge state ion production was installed on RHIC-EBIS. This is the first LIS to be combined with an Electron Beam Ion Source (EBIS) type heavy ion source. The LIS provides intense low charge state ions from any solid state material, with low emittance and narrow pulse length. These features make it suitable as an external source of 1+ ions that can be injected into the EBIS trap for charge breeding. In addition, a LIS is the only type ion source which can allow rapid switching among many ion species, even on pulse-by-pulse basis, by changing either laser path or target position, to strike the material of choice. The EBIS works as a charge breeder, with the extracted high charge state ions used in the following accelerators. The beams from LIS will be used for RHIC and NASA Space Radiation Laboratory (NSRL) at BNL. The rapid beam switching, which was not possible with existing ion sources, will expand the research field at NSRL as a galactic cosmic ray simulator. The results of commissioning will be shown.
