1 RHIC – p+p and p+Au projections for March 2014 STAR meeting

22 p+p luminosity projections Luminosity increase driven by bunch intensity and bunch length, based on New polarized source (first operated in 2013) Electron lenses (under commissioning) Pile-up at peak luminosity going from 1.7 (2013) to 7.7 (2018)

33 Capital project FY , $1.1M Commissioned before and during Run-13 Reliable operation Maintenance time significantly reduced Performance increase to date Maximum Booster intensity: 2x higher than Run-12 Polarization: 81%, 2% higher than Run-12 (at nominal intensity 5x10 11 ) Expect further intensity and polarization increases Will be primarily used to increase brightness Polarization at store can be reduced by accelerating smaller beams Optically Pumped Polarized H – source (OPPIS) – A. Zelenski New Atomic Beam Source (ABS) New superconducting solenoid Setup on 10 May 2012

4 4 installed Blue lens installed Yellow lens Goal: ~2x increase in average polarized proton luminosity Both lenses installed Magnetic structure operational (3 T of 6 T for main field so far) Demonstrated 1 A pulsed e-beam in Blue/Yellow, 1 A DC in Yellow Running with pulsed e-beams parasitically to Au+Au stores First beam-beam experiments expected on 3 April 2014 Working on transverse alignment of electron and proton beams Expect to be operational for Run-15 Electron lenses – under commissioning

55 In addition to OPPIS and electron lenses a number of other systems need to be readied for high-intensity operation: SAD/ASE – completed 2011 Evaluated Booster/AGS/RHIC effects (CAD MAC-08, 2012) Evaluated: ramp efficiency, radiation safety, beam dump, collimation system, rf systems, resistive wall heating, instabilities, cryogenic BPM cables Need: Dump kicker upgrade (ferrite heating with beam current) – summer 2014 Orbit interlock to prevent BPM cable overheating – tested in Run-13 High-intensity operation

66 Pile-up of up 8 events per bunch-bunch crossing at peak luminosity Could be reduces with lower initial  * and subsequent  *-squeeze during the store Planning to test a similar scheme during Run-14 Au+Au Still need full beam-beam compensation with electron lenses (beam-beam effect independent of  *) Dynamic  * squeeze will reduce delivered luminosity (but may increase useful luminosity) Possible pile-up mitigation

77 p+Au luminosity projections Luminosity increase driven by bunch intensity, based on New polarized source for protons (first operated in 2013) Incremental increases for Au ions (EBIS/Booster/AGS/RHIC) Electron lenses (under commissioning)
