	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy The Coherent Electron Cooling (CeC) Proof-of-Principle experiment [1], installed in the RHIC tunnel at BNL, has completed its second run. In this experiment, an FEL is used to amplify patterns imprinted on the cooling electron beam by the RHIC ion bunches and then the imprinted pattern is fed back to the ions to achieve cooling of the ion beam. Diagnostics for the CeC experiment have been fully commissioned during this year’s run. An overview of the beam instrumentation is presented, this includes devices for measurements of beam current, position, profile, bunch charge, emittance, as well as gun photocathode imaging and FEL infra-red light emission diagnostics. Design details are discussed and beam measurement results are presented. [1] I.

TUOB01	Coherent Electron Cooling Diagnostics: Design Principles and Demonstrated Performance
	I. Pinayev, J.C.B. Brutus, D.M. Gassner, R.L. Hulsart, P. Inacker, V. Litvinenko, R.J. Michnoff, T.A. Miller, M.C. Paniccia, W.E. Pekrul, Z. Sorrell, J.E. Tuozzolo BNL, Upton, Long Island, New York, USA
	The Coherent electron Cooling (CeC) Proof of Principle Experiment at Brookhaven National Laboratory utilizes a 14 MeV CW electron accelerator and an FEL structure to demonstrate longitudinal cooling of gold ions circulating in the Relativistic Heavy Ion Collider. This unique combination requires proper selection of the diagnostics devices and their parameters. In this paper we present how we transformed design beam parameters into specifications for the instrumentation and hardware configuration. We also have developed tools enhancing diagnostics capabilities including solenoid beam-based alignment and in-line energy measurement. The achieved beam parameters as well as instrument performance are also shown.

	The low energy RHIC Electron Cooler (LEReC) will be operating with 1.6-2.6 MeV electron beams having up to 140 kW power. It was determined that under the worst case scenario the missteered electron beam can damage the vacuum chamber and in-vacuum components within 40 us. Hence, the LEReC requires a dedicated fast machine protection system (MPS). The LEReC MPS has been designed and built and currently is under commissioning. In this paper we describe the most recent developments with the LEReC MPS.
