Caption: NA45 particle detector. Technician adjusting the NA45 particle detector at CERN, used to study the subatomic particles formed from the recombination of particles from a quark-gluon plasma. Quarks are thought to be the fundamental building blocks of matter. A quark-gluon plasma, in which the particles are not bound together, had not existed since just after the formation of the universe in the Big Bang. The quark- gluon plasma was created by colliding lead nuclei to densities 20 times that of nuclear matter and a temperature 100, 000 times that at the Sun's centre. Study of such plasma will allow a greater understanding of the early universe. CERN is in Geneva, Switzerland.
