How Data Becomes Physics: Inside the RACF
The RHIC & ATLAS Computing Facility (RACF) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory sits at the center of a global computing network. It connects more than 2,500 researchers around the world with the data generated by millions of particle collisions taking place each second at Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC, a DOE Office of Science User Facility for nuclear physics research), and the ATLAS experiment at the Large Hadron Collider in Europe. Watch this video to learn how the people and computing resources of the RACF serve these scientists to turn petabytes of raw data into physics discoveries.
Using Nuclei to Catch Shape-Shifting Protons in the Act: One Hypothesis, Two Colliders
During the 508th Brookhaven Lecture, Dennis Perepelitsa introduces his hypothesis that protons with most of their energy concentrated in single quarks or gluons are particularly small and shaped differently too. He then describes his analysis of data from particle collisions at the Relativistic Heavy Ion Collider and the Large Hadron Collider to test his hypothesis.
Science Friday Explains "How to Make Quark Soup"
You don't need a time machine to marvel at the hot broth of quarks and gluons that made up all matter a microsecond after the Big Bang. You just need a ticket on the Long Island Railroad. Through massive feats of engineering, Brookhaven National Laboratory has devised a recipe for cooking up tiny ephemeral batches of this quark-gluon soup, a fluid which physicists Paul Sorensen say is the most "perfect" fluid ever discovered.

If you want to know how the universe works, part of the answer lies in understanding the building blocks of matter—before they became inextricably bound within the protons, neutrons, and atoms that make up everything visible in our universe today.
Special PET Scans Seeking Symmetry in Quark-Gluon Plasma
During the 496th Brookhaven Lecture, Lijuan Ruan explained how she uses electron-positron tomography from quark-antiquark annihilations to study chiral symmetry, a characteristic that "broke" to form 99 percent of the visible mass in the universe and is thought to be restored during ion collisions at the Relativistic Heavy Ion Collider.

Keeping RHIC's Beam Tight and the Orbit Right
Physicist Michiko Minty explains how bunches of particles traveling in opposite directions in each of the Relativistic Heavy Ion Colliderâ€™s (RHIC) two superconducting rings are guided, focused, and accelerated to nearly the speed of light and then made to collide. She describes how to ensure the highest possible collision rates by establishing head-on collisions between the two-foot-long bunches which, at the interaction points, are a width comparable to a human hair.

Hot Quark Soup Produced at RHIC
The Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic ) is a 2.4-mile-circumference particle accelerator/collider that has been operating at Brookhaven Lab since 2000, delivering collisions of heavy ions, protons, and other particles to an international team of physicists investigating the basic structure and fundamental forces of matter. In 2005, RHIC physicists announced that the matter created in RHICs most energetic collisions behaves like a nearly perfect liquid in that it has extraordinarily low viscosity, or resistance to flow. Since then, the scientists have been taking a closer look at this remarkable form of matter, which last existed some 13 billion years ago, a mere fraction of a second after the Big Bang. Scientists have revelaed new findings, including the first measurement of temperature very early in the collision events, and their implications for the nature of this early-universe matter.

A celebration of the contribution that Renaissance Technologies, Inc., made to the Relativistic Heavy Ion Collider, during which the entire Lab community participated in a series of RHIC Renaissance events, beginning with the Roads to Discovery ceremony, followed by a 1.8-mile 'Collide the Ions' walk for autism research around the newly re-dedicated RHIC Ring Road. The days activities also include talks preceding and following the walk.

Copper vs. Copper at the Relativistic Heavy Ion Collider
To investigate a new form of matter not seen since the Big Bang, scientists are using a new experimental probe: collisions between two beams of copper ions. The use of intermediate size nuclei is expected to result in intermediate energy density - not as high as in earlier runs colliding two beams of gold ions at the Relativistic Heavy Ion Collider (RHIC), but more than was produced by colliding a beam of gold ions with much lighter deuterons.
Coordinating the 2009 RHIC Run
Physicists working at the Brookhaven National Lab's Relativistic Heavy Ion Collider (RHIC) are exploring the puzzle of proton spin as they begin taking data during the 2009 RHIC run. For the first time, RHIC is running at a record energy of 500 giga-electron volts (GeV) per collision, more than double the previous runs in which polarized proton beams collided at 200 GeV. Narrarated by RHIC run coordinator Mei Bai.
RHIC: The Perfect Liquid
Evidence to date suggests that gold-gold collisions the Relativistic Heavy Ion Collider at Brookhaven are indeed creating a new state of hot, dense matter, but one quite different and even more remarkable than had been predicted. Instead of behaving like a gas of free quarks and gluons, as was expected, the matter created in RHIC's heavy ion collisions appears to be more like a "perfect" liquid.
RHIC - Exploring the Universe Within
A guided tour of Brookhaven's Relativistic Heavy Ion Collider (RHIC) conducted by past Laboratory Director John Marburger. RHIC is a world-class scientific research facility that began operation in 2000, following 10 years of development and construction. Hundreds of physicists from around the world use RHIC to study what the universe may have looked like in the first few moments after its creation. RHIC drives two intersecting beams of gold ions head-on, in a subatomic collision. What physicists learn from these collisions may help us understand more about why the physical world works the way it does, from the smallest subatomic particles, to the largest stars.
