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..

Optimization of AGS Polarized Proton Operation with the Warm Helical Snake
/ Takano, Junpei ; Ahrens, Leif ; Bai, Mei ; Brown, Kevin A ; Gardner, Chris J ; Glenn, Joseph ; Hattori, Toshiyuki ; Huang, Haixin ; Luccio, Alfredo U ; MacKay, William W et al.
A normal conducting helical dipole partial Siberian snake (Warm Snake) has been installed in the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory (BNL) for overcoming all of imperfection depolarizing resonances and reducing the transverse coupling resonances caused by the solenoidal Siberian snake which had been operated in AGS before the last polarized run. The polarized proton beam has been accelerated successfully with the warm snake and the polarization at extraction of the AGS was increased to 50% as opposed to 40% with the solenoidal snake. [...]

Tomographic Measurement of Longitudinal Emittance Growth Due to Stripping Foils
/ Montag, Christoph ; Ahrens, Leif ; Thieberger, Peter
During beam acceleration at the Brookhaven accelerator complex, heavy ions are stripped off their electrons in several steps. Depending on the properties of the stripping foils, this process results in an increased energy spread and therefore longitudinal emittance growth. [...]

Design Concept for AGS Injection Kicker Upgrade to 2 GeV
/ Dale Wait, Gary ; Ahrens, Leif ; Armenta, Roberto ; Barnes, Michael J ; Blackmore, Ewart W ; Gardner, Chris J ; Hadary, Ori ; Zhang, Wu
The present AGS injection kickers at A5 location were designed for 1.5 GeV proton injection. Recent high intensity runs have pushed the transfer kinetic energy to 1.94 GeV, but with an imperfect matching in transverse phase space [...]
