	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Dept. of Energy Brookhaven National Laboratory's BLIP facility produces radioisotopes for the nuclear medicine community and industry, and performs research to develop new radioisotopes desired by nuclear medicine investigators. A raster scanning system was recently completed in December 2015 and fully commissioned in January 2016 to provide improved beam distribution on the targets, allow higher beam intensities, and ultimately increase production yield of the isotopes. The project included the installation of horizontal and vertical dipole magnets driven at 5 kHz with 90 deg phase separation to produce a circular beam raster pattern, a beam interlock system, and several instrumentation devices including multi-wire profile monitors, a laser profile monitor, beam current transformers and a beam position monitor. The first year operational experiences will be presented.

MOPG69	Study of YAG Exposure Time for LEReC RF Diagnostic Beamline	233
	S. Seletskiy, T.A. Miller, P. Thieberger BNL, Upton, Long Island, New York, USA
	The LEReC RF diagnostic beamline is supposed to ac-cept 250 us long bunch trains of 1.6 MeV ' 2.6 MeV (kinetic energy) electrons. This beamline is equipped with a YAG profile monitor. Since we are interested in observ-ing only the last bunch in the train, one of the possibilities is to install a fast kicker and a dedicated dump upstream of the YAG screen and related diagnostic equipment. This approach is expensive and challenging from an engineer-ing point of view. Another possibility is to send the whole bunch train to the YAG screen and to use a fast gated camera to observe the image from the last bunch only. In this paper we demonstrate the feasibility of the last ap-proach, which significantly simplifies the overall design of the RF diagnostic beamline.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy RHIC will be run at low ion beam center-of-mass energies of 7.7 - 20 GeV/nucleon, much lower than the typical operations at 100 GeV/nucleon. The primary motivation is to explore the existence and location of the critical point on the QCD phase diagram. An electron accelerator is being constructed to provide Low Energy RHIC electron Cooling (LEReC) to cool both the blue & yellow RHIC ion beams by co-propagating a 10 - 50 mA electron beam of 1.6 - 2.6 MeV. This cooling facility will include a 400 keV DC gun, SRF booster cavity and a beam transport with multiple phase adjusting RF cavities to bring the beam to one ring to allow electron-ion co-propagation for ~21 m, then through a 180° U-turn electron transport so that the same electron beam can similarly cool the other counter-rotating ion beam, and finally to a beam dump. The injector commissioning is planned to start in early 2017 and full LEReC commissioning planned to start in early 2018. The instrumentation systems that will be described include current transformers, BPMs, profile monitors, multi-slit and single slit scanning emittance stations, time-of-flight and magnetic energy measurements, and beam halo & loss monitors.

	The low energy RHIC Electron Cooling (LEReC) accelerator will be running with electron beams of up to 110 kW power with CW operation at 704MHz. Although electron energies are relatively low (< 2.6MeV), at several locations along the LEReC beamline, where the electron beam has small (about 250 um RMS radius) design size, it can potentially hit the vacuum chamber at a normal incident angle. The accelerator must be protected against such a catastrophic scenario by a dedicated machine protection system (MPS). Such an MPS shall be capable of interrupting the beam within a few tens of microseconds. In this paper we describe the current conceptual design of the LEReC MPS.
