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.
From the Associate Director
By Steven Vigdor
I will try to provide roughly monthly updates in the RHIC News on items of RHIC/AGS policy of general interest to users. In this first communication, I have good news and bad news. Let me start with the bad news, since this may call for some involvement by users. More...
Size, Energy, Centrality and Pseudorapidity Dependence of
Charged Particle Density in Nucleus-Nucleus Collisions at RHIC
By Rachid Nouicer
In ultrarelativistic heavy ion collisions, the charged particle multiplicities have been studied extensively because of the intrinsic interest in understanding the production mechanism. More recent interest comes in the context of searching for and studying new forms of matter that are expected to be created in heavy ion collisions at these energies. A key quantity that contains information about the longitudinal aspects of the multiparticle production process, and that has provided valuable input for discriminating between phenomenological models in the past, is the rapidity distribution of identified particles.

Preparing for Run 8
By Don Lynch
As summer ends, the weather cools, and the leaves begin to fall, it is once again time to button up the PHENIX experiment and prepare for the next RHIC run. From June to September each year the RHIC accelerators are shut down and the annual rituals of maintenance, upgrades and enhancements are undertaken by the technical staffs of the Collider-Accelerator Department and the major experiments at RHIC.

Beam in Run 8
By Fulvia Pilat
Together with the glorious foliage and the kids happily back in school, autumn this year, brought back another cycle of RHIC operations, as it has been possible to start Run-8 even in the presence of a budget continuing resolution. This is extremely beneficial to the effective running of operations in that it avoids last year conflicting needs of progressively delaying the schedule while keeping the accelerators ready to go.
