Funding: This work was supported by U.S. Department of Energy, Office of Basic Energy Sciences, under Contract DE-AC02-76SF00515 Oxygen is tested as a replacement for Nitrogen in the Gas Detector system in the Linac Coherent Light Source (LCLS) x-ray Free Electron Laser (FEL) at the SLAC National Accelerator Center. The attenuation and energy monitors for LCLS use Nitrogen, but for experiments at the Nitrogen K 1S energy of about 410eV this functionality is gone due to energy fluctuations above and below the K-edge. Oxygen was tested as a scintillating gas at 400eV and 8.3keV. |

Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy The purpose of the Coherent electron Cooling Proof-of- Principle (CeC PoP) [1] experiment being designed at RHIC is to demonstrate longitudinal (energy spread) cooling before the expected CD-2 for eRHIC. The scope of the experiment is to longitudinally cool a single bunch of 40 GeV/u gold ions in RHIC. The cooling facility will be installed inside the RHIC tunnel in 3 phases. The status of the instrumentation systems planned for phase 1 commissioning efforts will be described. This paper will also describe updates to the instrumentation systems proposed to meet the diagnostics challenges during the final phase of cooling commissioning [2]. These include measurements of beam intensity, emittance, energy spread, bunch length, position, and transverse alignment of electron and ion beams. |
