Liquid Scintillator Neutrino Detector (original) (raw)
LSND (Liquid Scintillator Neutrino Detector, engl. für „Flüssig-Szintillator-Neutrino-Detektor“) war ein physikalisches Experiment am Los Alamos National Laboratory. Es diente zur Untersuchung von Neutrinooszillationen und lief von 1993 bis 1998. Das Ergebnis wurde als Hinweis auf bisher unbekannte sterile Neutrinos außerhalb des Standardmodells der Teilchenphysik interpretiert, war jedoch von Anfang an stark umstritten.

(de) The Liquid Scintillator Neutrino Detector (LSND) was a scintillation counter at Los Alamos National Laboratory that measured the number of neutrinos being produced by an accelerator neutrino source. The LSND project was created to look for evidence of neutrino oscillation, and its results conflict with the standard model expectation of only three neutrino flavors, when considered in the context of other solar and atmospheric neutrino oscillation experiments. Cosmological data bound the mass of the sterile neutrino to ms < 0.26eV (0.44eV) at 95% (99.9%) confidence limit, excluding at high significance the sterile neutrino hypothesis as an explanation of the LSND anomaly. The controversial LSND result was tested by the MiniBooNE experiment at Fermilab which has found similar evidence for oscillations.The hint is currently undergoing further tests at MicroBooNE at Fermilab. The detector consisted of a tank filled with 167 tons (50,000 gallons) of mineral oil and 14 pounds (6.4 kg) of b-PDB (2-(4-tert-butylphenyl)-5-(4-biphenyl)-1,3,4-oxadiazole) organic scintillator material. Cherenkov light emitted by particle interactions was detected by an array of 1220 photomultiplier tubes. The experiment collected data from 1993 to 1998. (en) |
