In this 481st Brookhaven Lecture, Vladimir Litvinenko describes the cutting-edge developments accelerator physicists are planning along the path to new, exciting science at RHIC. He explains new techniques, including coherent electron cooling, generating a high-current, polarized electron beam, and ways of suppressing a myriad of potential instabilities.
Physicist Paul Sorensen describes discoveries made at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory. At RHIC, scientists from around the world study what the universe may have looked like in the first microseconds after its birth, helping us to understand more about why the physical world works the way it does -- from the smallest particles to the largest stars.
On December 5, 2011, the PHENIX collaboration celebrated its 20th anniversary at a symposium, which began with some speakers’ recollections of early challenges and struggles in getting PHENIX approved, designed, and built. The speakers continued their talks with recounts of the many successes that occurred during the first 11 years of operations at RHIC, and ended with predictions of continued success for both RHIC and PHENIX in the next decade.
Physicist Michiko Minty explains how bunches of particles traveling in opposite directions in each of the Relativistic Heavy Ion Collider’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.
Modern, compact ion injector will feed new kinds of particles to RHIC and NSRL.
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.
'Collide the Ions' walkers dressed in blue and yellow T-shirts walked around Brookhaven Lab's Relativistic Heavy Ion Collider ring road in opposite directions. Halfway around the ring, the walkers symbolically "collided."
Physicist Peter Steinberg explains the nature of the quark gluon plasma (QGP), a new state of matter produced at Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC).
Physicist Peter Steinberg explains what happens when atomic nucleii travelling at close to the speed of light smash together in Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC).
Physicist Peter Steinberg explains that fundamental particles like protons are themselves made up of still smaller particles called quarks. He discusses how new particles are produced when quarks are liberated from protons...a process that can be observed in Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC).
An animation that follows polarized protons as they travel through the Relativistic Heavy Ion Collider (RHIC) accelerator complex to the experiments. The arrows indicate the direction of each proton's spin. The animation concludes with a fly-by of the RHIC experiments running during the spin program.
Physicist Tim Hallman discusses the properties of the "perfect" liquid and plans for luminosity and detector upgrades to the Relativistic Heavy Ion Collider.
Brookhaven National Lab has successfully developed a new pre-injector system, called the Electron Beam Ion Source, for the Relativistic Heavy Ion Collider (RHIC) and NASA Space Radiation Laboratory science programs. The first of several planned improvements to the RHIC facility, EBIS will help transform RHIC into the Quantum Chromo Dynamics Lab that will enable the study of QCD in more detail.
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.
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.
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.
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.

Bjoern Schenke, a Goldhaber Fellow in the nuclear theory group at the U.S. Department of Energy's Brookhaven National Laboratory, has been awarded a Young Scientist Prize in nuclear physics by the International Union of Pure and Applied Physics (IUPAP).
When heavy ions collide at high energies at Brookhaven's Relativistic Heavy Ion Collider, the components of the nuclei melt to form a hot soup of their constituent particles. A new model that describes the patterns of particles flowing out from this "quark-gluon plasma" suggests that the resistance to flow is close to the ideal limit used to define a "perfect" fluid.
