Research at HEHI

The group is currently involved in three experiments:

ALICE

ALICE

ALICE (A Large Ion Collider Experiment) is currently being designed and built. It will be the only dedicated heavy-ion experiment at the LHC (Large Hadron Collider) at CERN. Once opperational in 2005, it will be the world's most powerful tool for studying the "Little Big Bang".

The HEHI group is invovled with the Laser Calibration System for the TPC, and the Forward Multiplicity Detector (FMD). Some internal pages for the FMD working group can be found here (restricted access).

BRAHMS

BRAHMS

BRAHMS (from Broad RAnge Hadron Magnetic Spectrometers) is one of the four experiments at RHIC (Relavistic Heavy Ion Collider) situated at BNL (Brookhaven National Laboratories).

RHIC, the world's first heavy-ion collider, became fully operational in July 2000. RHIC is capable of accelerating two countercirculating beams of ions as heavy as Gold, up to energies of 100 GeV per nucleon. Each Gold on Gold collision at the highest energy creates a 'Little Big Bang'--producing around 10,000 particles.

BRAHMS consists of two high precision magnetic spectrometers. The detector systems in the spectrometers make it possible to dentify and characterize charged particles over a large range in momentum and rapidity. A group of about 15 physicists, students, and technicians from NBI participate in BRAHMS.

NA44

NA44

The NA44 focussing spectrometer took data for Pb + Pb collisions at the SPS at CERN until 1996. These data have been, and are currently being, used to study many aspects of hadronic physics via single particle distributions, as well as two- and three-particle correlations.
