==The experiments==

There are two [[detectors]] currently operating at RHIC: [[STAR detector|STAR]] (6 o'clock, and near the AGS-to-RHIC Transfer Line) and [[sPHENIX detector|sPHENIX]] (8 o'clock), the successor to [[PHENIX detector|PHENIX]]. PHOBOS (10 o'clock) completed its operation in 2005, and BRAHMS (2 o'clock) in 2006.

Among the two larger detectors, STAR is aimed at the detection of [[hadron]]s with its system of [[time projection chamber]]s covering a large [[solid angle]] and in a conventionally generated solenoidal [[magnetic field]], while PHENIX is further specialized in detecting rare and electromagnetic particles, using a partial coverage detector system in a superconductively generated axial magnetic field. The smaller detectors have larger [[pseudorapidity]] coverage, PHOBOS has the largest [[pseudorapidity]] coverage of all detectors, and tailored for bulk particle multiplicity measurement, while BRAHMS is designed for momentum spectroscopy, in order to study the so-called "small-''x''" and saturation physics. There is an additional experiment, PP2PP (now part of STAR), investigating [[Spin (physics)|spin]] dependence in p&nbsp;+&nbsp;p [[scattering]].<ref>{{cite web
