The PHENIX Collaboration conducts research with high energy collisions of heavy ions and protons. The primary mission of PHENIX is the following:
Search for a new state of matter called the Quark-Gluon Plasma, which is believed to be the state of matter existing in the universe shortly after the Big Bang. The data obtained by PHENIX suggest that a new form of matter has indeed been discovered, and that it behaves like a perfect fluid.
Study matter under extreme conditions of temperature and pressure, and create a map of the Quantum Chromodynamics phase diagram.
Learn where the proton gets its spin.
Study the most basic building blocks of nature and the forces that govern them.
PHENIX finished taking data in 2016. A number of analyses are continuing, with emphasis on those with a physic reach unique to PHENIX.
August 1991: PHENIX is born from the merger of proposals named TALES, SPARC, OASIS, and DIMUON.
PHENIX is designed, built, and installed at RHIC.
June 15, 2000 at 6:28 am EDT: PHENIX records its first relativistic heavy ion collision.
Summer of 2000: RHIC Run-1. PHENIX takes data from reduced RHIC energy Gold-Gold collisions.
