MINOS

Main injector neutrino oscillation search (MINOS) was a <a href="/facts/Particle_physics/YgIuyj2t">particle physics</a> experiment designed to study the phenomena of <a href="/facts/Neutrino_oscillation/c1cc5noc">neutrino oscillations</a>, first discovered by a <a href="/facts/Super-Kamiokande/pvvQ3ogI">Super-Kamiokande</a> (Super-K) experiment in 1998. <a href="/facts/Neutrino/yGWVfSg2">Neutrinos</a> produced by the <a href="/facts/NuMI/30RQT87C">NuMI</a> ("Neutrinos at Main Injector") <a href="/facts/Accelerator_neutrino/6JvA3Rm1">beamline</a> at <a href="/facts/Fermilab/8yyTx3oj">Fermilab</a> near <a href="/facts/Chicago/yPMokrXH">Chicago</a> are observed at two detectors, one very close to where the beam is produced (the near detector), and another much larger detector 735 km away in northern <a href="/facts/Minnesota/ncgVuC4Q">Minnesota</a> (the far detector).
The MINOS experiment started detecting neutrinos from the NuMI beam in February 2005. On 30 March 2006, the MINOS collaboration announced that the analysis of the initial data, collected in 2005, is consistent with neutrino oscillations, with the oscillation parameters which are consistent with Super-K measurements.
MINOS received the last neutrinos from the NUMI beam line at midnight on 30 April 2012. It was upgraded to <a href="/facts/MINOS%2B/0WGEXNFC">MINOS+</a> which started taking data in 2013. The experiment was shut down on June 29, 2016, and the far detector has been dismantled and removed. It was moved to Puerto Vallarta, Jalisco in Mexico.
