Luminosity Plot

RHIC integrated luminosity in units inverse micro barns as a function of days in Run7 for the four interaction regions together with our least optimistic predictions (dark blue dots and line) and our most optimistic predictions (grey dots and line). The least optimistic predictions are based on an extrapolation of our most successful week in Run 4, the most optimistic scenario is based on a beta* value of 0.9 m, 111 bunches, 1.1e9 ions/bunch and an average time at store of 60%. The luminosity numbers are corrected for accidental coincidences in the ZDCs.

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.

Electron Cooling of RHIC By Ilan Ben-Zvi
Discoveries at the Relativistic Heavy Ion Collider (RHIC) have captured worldwide attention. They’ve also raised compelling new questions about the theory that describes the interactions of the smallest known components of the atomic nucleus. To address these questions, we need to to study rare processes and thus to increase the collider’s luminosity, or the rate at which ions collide inside the accelerator.  More...

DAQ1000 Project: Upgrade of STAR TPC's Detector Electronics & DAQ by Tonko Ljubicic
The STAR experiment at RHIC is undergoing a series of major detector upgrades which should be completed in the following years. One of these is the upgrade of the electronics and the data acquisition system (DAQ) of its most important detector, the Time Projection Chamber (TPC). The goal is to be able to record a 1000 Hz event rate with minimal detector deadtime which represents a factor of 20 increase from today. More...

APEX: Accelerator Physics Experiments at RHIC by Fulvia Pilat
It is late at night on a Tuesday or early at sunrise on a Wednesday and the RHIC Main Control Room (MCR) is getting ready for an APEX shift: instead of the usual quiet work of the evening or owl operation crews who efficiently attend to the need of the accelerators and the RHIC physics experiments, teams of accelerator physicist start to show up. Accelerator physicists, supported by machine and system specialists as well as operators collaborate on testing the latest and newest beam techniques proposed for RHIC. More...
