COMPASS experiment

<p>The NA58 experiment, or COMPASS (standing for "Common Muon and Proton Apparatus for Structure and Spectroscopy") is a 60-metre-long <a href="/facts/Fixed-target_experiment/VAy6wGvF">fixed-target experiment</a> at the M2 beam line of the <a href="/facts/Super_Proton_Synchrotron/3qTKCxnR">SPS</a> at <a href="/facts/CERN/y1gwRchm">CERN</a>. The experimental hall is located at the CERN North Area, close to the French village of Prévessin-Moëns. The experiment is a two-staged <a href="/facts/Spectrometer/IqRE8xaQ">spectrometer</a> with numerous tracking detectors, particle identification and calorimetry. The physics results are extracted by recording and analysing the final states of the scattering processes. 
</p>

<p>The versatile set-up, the use of different targets and particle beams allow the investigation of various processes. The main physics goals are the investigation of the <a href="/facts/Nucleon_spin_structure/nl1jLhJ7">nucleon spin structure</a> and <a href="/facts/Hadron_spectroscopy/I0y82456">hadron spectroscopy</a>. The collaboration consists of 220 physicists from 13 different countries, involving 28 universities and research institutes.
