MINOS far detector at Fermilab
Numéro d’image : 12000754
| The MINOS far detector is located in a cavern half a mile underground in the Soudan Underground Laboratory,Minnesota. The 100-foot-long MINOS far detector consists of 486 massive octagonal planes,lined up like the slices of a loaf of bread. Each plane consists of a sheet of steel about 25 feet high and one inch thick,with the last one visible in the photo. The whole detector weighs 6,000 tons. Since August 2003,the far detector has collected data on cosmic rays and neutrinos. Now,scientists are using the detector to record man-made neutrinos. The MINOS collaboration expects to record about 1,000 neutrinos per year. Neutrinos,ghost-like particles that rarely interact with matter,travel 450 miles straight through the earth from Fermilab to Soudan -- no tunnel needed. The Main Injector Neutrino Oscillation Search (MINOS) experiment studies the neutrino beam using two detectors. The MINOS near detector,located at Fermilab,records the composition of the neutrino beam as it leaves the Fermilab site. The MINOS far detector,located in Minnesota,half a mile underground,again analyzes the neutrino beam. This allows scientists to directly study the oscillation of muon neutrinos into electron neutrinos or tau neutrinos under laboratory conditions | |
