Welcome to RHIC News

We hope that this web publication will in some small measure reflect the excitement of the RHIC and AGS program at Brookhaven, as explained by some of the people who are doing the experiments, analyzing the data, and writing the papers.

SteinbergHeavy Ion Physics with the ATLAS Detector by Peter Steinberg
The LHC is set to be a major part of the physics of the next decade. However, one oft-neglected fact is that the LHC has the potential not just for discovering new particles, but for creating the same "near-perfect fluid" we create at RHIC -- but hotter, denser, and longer-lived. Brookhaven is a major institution in the ATLAS experiment, with almost 1800 scientific collaborators.  More...

cooling diagramStochastic Cooling in RHIC by Mike Blaskiewicz
During heavy ion operations a typical RHIC bunch contains about a billion particles. The individual particles undergo transverse focusing by the magnets and are kept longitudinally bunched by electric fields generated by radio frequency (RF) cavities.  The energy spread of the beam increases to the point that the RF can no longer keep all the particles bunched. This results in fewer collisions, reducing useful physics data. The purpose of the stochastic cooling system is to keep the beam bunched. More...

Jeff MitchellMeasuring Fluctuations in RHIC Collisions
by Jeffrey Mitchell
A new form of nuclear matter that appears to have the properties of a perfect liquid is currently being studied at RHIC. This new form of matter is created in collisions of pairs of ions that initially contain ordinary nuclear matter. During the collisions, the nuclear matter is heated and compressed to a very high degree. At some point during the collision, the matter goes through a phase transition to the new state. More...
