Relativistic heavy ion physics creating mini big bangs in the laboratory

Relativistic Heavy Ion Physics:Creating Mini-`Big Bangs’ in the Laboratory

1) Goal: Use relativistic collisions of nuclear to create hot dense matter which reproduces the earliest stages of the universe

2) Now, how do we do this?

(In Theory)

How to take the temperature

How to Take the Temperature

  • Determine the momentum of each ‘track’

  • Identify the particle type of each track

  • Assume that the particles are emitted from an equilibrated gas

  • Temperatures are measured in the range expected for a QGP transition

The Hottest matter in the Universe

Relativistic Heavy Ion Collider

Brookhaven National Laboratory

Upton, New York

Scientists have recently set records for both the highest and lowest measured temperatures.

The high temperatures approach those of the early stage of the Big Bang.

  • Relativistic Heavy Ion Collisions1.3x1012 K (2002)

  • Thermonuclear Fusion Device 3x106 K

  • The surface of the Sun 5800 K

  • The hottest place in the Solar system (Io) 2000 K

  • The highest recorded temperature on earth (Libya) 330 K

  • Room Temperature 300 K

  • Coldest place on Earth 184 K (Vostock Station - Antarctica)

  • Air turns to liquid 73 K

  • Coldest place in the solar system (Triton) 38K

  • Helium turns to liquid 4.2 K

  • Dilution Refrigeration .002 K

  • Magnetic Cooling 90 mK

  • Ion Trapping10 nK (1999)
