The four electron stripping stages leading to fully stripped gold ions in the Relativistic Heavy Ion Collider (RHIC) are briefly described. third stripper, which removes 46 electrons from ${\mathrm{Au}}^{31+}$ heliumlike ${\mathrm{Au}}^{77+}$, offers greatest challenges terms of energy loss and induced spread. These problems described detail as well recent advances design performance this stripper. Measurements performed with several carbon aluminum strippers show general agreement a...
Gold ions for the 2007 run [1] of relativistic heavy ion collider (RHIC) at Brookhaven National Laboratory (BNL) are accelerated in Tandem,Booster and AGS prior to injection into RHIC. The setup performance this chain accelerators is reviewed with a focus on improvements quality beam delivered In particular,more uniform stripping foils between Booster AGS,and new bunch merging scheme have provided bunches reduced longitudinal emittance
There is significant interest in RHIC heavy ion collisions at radics =5-50 GeV/u, motivated by a search for the QCD phase transition critical point. The lowest energies are well below nominal gold injection = 19.6 GeV/u. several challenges that face operations this regime, including longitudinal acceptance, magnet field quality, lattice control, and luminosity monitoring. We report on status of work to address these challenges, results from beam tests low energy with protons gold.
The 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> year of RHIC operations, started in November 2004 and expected to last till June 2005, consists a physics run with Cu-Cu collisions at 100 GeV/u followed by one polarized protons (pp) GeV [1]. We will address here the overall performance complex used for first time as collider, compare it previous operational experience Au, PP asymmetric d-Au collisions. also discuss improvements,...
The RHIC 2003 Physics Run required collisions between gold ions and deuterons. injector necessarily had to deliver adequate quality (transverse longitudinal emittance) quantity of both species. For this was a continuing evolution from past work. deuterons it new territory. the filling not only beams but also switch these species quickly. This paper details collider requirements our success in meeting these. Some configurations employed are given.
After the last successful RHIC Au-Au run in 2004 (Run-4), experiments now require significantly enhanced luminosity to study very rare events heavy ion collisions. has demonstrated its capability operate routinely above design average per store of 2times10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">26</sup> cm xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> s xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> .
