The NA49 experiment ("North Area experiment 49") was a particle physics experiment that investigated the properties of quark–gluon plasma. It took place in the North Area of the Super Proton Synchrotron at CERN from 1991-2002. It used a large-acceptance hadron detector (a time projection chamber) to investigate reactions induced by the collision of various heavy ions (such as those of lead) on targets made of a variety of elements.

The main components are 4 large-volume TPCs for tracking and particle identification via dE/dx. TOF scintillator arrays complement particle identification. Calorimeters for transverse energy determination and triggering, a detector for centrality selection in p+A collisions, and beam definition detectors complete the set-up.[1]
The NA49 experiment was the follow-up to the NA35 experiment, and was approved on 18 September 1991. The experiment began taking data in November 1994 and was completed on 19 October 2002. It was succeeded by the NA61 experiment (SHINE). The spokespersons for the experiment are Peter Seyboth (born 1939)[2] and Reinhard Stock.
