First test of BNL electron beam ion source with high current density electron beam
/ Pikin, Alexander (Brookhaven Natl. Lab.) ; Alessi, James G (Brookhaven Natl. Lab.) ; Beebe, Edward N (Brookhaven Natl. Lab.) ; Shornikov, Andrey (CERN) ; Mertzig, Robert (CERN) ; Wenander, Fredrik (CERN) ; Scrivens, Richard (CERN)
A new electron gun with electrostatic compression has been installed at the Electron BeamIon Source (EBIS) Test Stand at BNL. This is a collaborative effort by BNL and CERN teams with a common goal to study an EBIS with electron beam current up to 10 A, current density up to 10,000 A/cm2 and energy more than 50 keV. [...]

Setup and Performance of the RHIC Injector Accelerators for the 2005 Run with Copper Ions
/ Gardner, Chris J ; Ahrens, Leif ; Alessi, James ; Benjamin, John ; Blaskiewicz, Michael ; Brennan, Joseph M ; Brown, Kevin A ; Carlson, Charles ; De Long, Joseph ; Glenn, Joseph et al.
Copper ions for the 2005 run of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory are accelerated in the Tandem, Booster and AGS prior to injection into RHIC. The setup and performance of this chain of accelerators will be reviewed..

Progress on Test EBIS and the Design of an EBIS-Based RHIC Preinjector
/ Alessi, James ; Beebe, Edward ; Gould, Omar ; Kponou, Ahovi ; Lockey, Robert ; Pikin, Alexander I ; Prelec, Krsto ; Raparia, Deepak ; Ritter, John ; Snydstrup, Louis
Following the successful development of the Test EBIS at BNL,* we now have a design for an EBIS-based heavy ion preinjector which would serve as an alternative to the Tandem Van de Graaffs in providing beams for RHIC and the NASA Space Radiation Laboratory. This baseline design includes an EBIS producing mA-level currents of heavy ions (ex [...]

Beam Induced Pressure Rise at RHIC
/ Zhang, S Y ; Alessi, James ; Bai, Mei ; Blaskiewicz, Michael ; Cameron, Peter ; Drees, Angelika ; Fischer, Wolfram ; Gullotta, Justin ; He, Ping ; Hseuh Hsiao Chaun et al.
Beam induced pressure rise in RHIC warm sections is currently one of the machine intensity and luminosity limits. This pressure rise is mainly due to electron cloud effects. [...]

Polarized Proton Collisions at RHIC
/ Bai, Mei ; Ahrens, Leif ; Alekseev, Igor G ; Alessi, James ; Beebe-Wang, Joanne ; Blaskiewicz, Michael ; Bravar, Alessandro ; Brennan, Joseph M ; Bruno, Donald ; Bunce, Gerry et al.
The Relativistic Heavy Ion Collider~(RHIC) provides not only collisions of ions but also collisions of polarized protons. In a circular accelerator, the polarization of polarized proton beam can be partially or fully lost when a spin depolarizing resonance is encountered. [...]
