CERN Accelerating science

About us

NA61/SHINE (standing for "SPS Heavy Ion and Neutrino Experiment") is a particle physics experiment at the Super Proton Synchrotron (SPS) at the European Organization for Nuclear Research (CERN) The experiment studies the hadronic final states produced in interactions of various beam particles (pions, protons and beryllium, argon, and xenon nuclei) with a variety of fixed nuclear targets at the SPS energies.

The NA61/SHINE physics goals include:

  (i) measurements for physics of strong interactions, in particular, study the properties of the onset of deconfinement and search for the critical point of strongly interacting matter which is pursued by investigating p+p, p+Pb and nucleus-nucleus collisions and

  (ii) measurements for improving calculations of the initial neutrino beam flux in the long-baseline neutrino oscillation experiments as well as for more reliable simulations of cosmic-ray air showers.

About 140 physicists from 14 countries and 28 institutions work in NA61/SHINE, led by Marek Gazdzicki.
