MicroBooNE records first neutrino events
MicroBooNE, an experiment designed to measure neutrinos and antineutrinos generated by Fermilab’s Booster accelerator (CERN Courier September 2014 p8), has recorded its first neutrino events. Mi...
DUNE and its CERN connection
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino-oscillation experiment, currently under review by the US Department of Energy (DOE). DUNE has a potentially ...
Borexino finds evidence of neutrinos produced in the Earth’s mantle
In July, the Borexino collaboration reported a geoneutrino signal from the Earth’s mantle with 98% C.L. Geoneutrinos are electron antineutrinos produced by β decays of 238U and 232Th c...
An improved measurement of θ13 from Daya Bay
The Daya Bay Reactor Neutrino Experiment has recently published a new measurement of the disappearance of electron antineutrinos emitted by nuclear reactors. The observation improves the precision of ...
What’s next for OPERA’s emulsion-detection technology?
Developed in the late 1990s, the OPERA detector design was based on a hybrid technology, using both real-time detectors and nuclear emulsions. The construction of the detector at the Gran Sasso...
Event view of highest energy neutrino detected by IceCube
This is an event view of the highest energy neutrino detected so far by the IceCube experiment based at the South Pole (CERN Courier December 2014 p30). Each sphere is one optical sensor; the coloured...
Fermilab sets neutrino-beam record
In June, Fermilab’s Main Injector accelerator sustained a 521 kW proton beam, and set a world record for the production of high-energy neutrinos with a proton accelerator. The 120 GeV ...
Fifth event signals discovery of ντ appearance
Setting out from CERN as a muon neutrino, the particle was detected at Gran Sasso as a ντ after travelling 730 km through the Earth.
A new neutrino telescope for Lake Baikal
In early April, members of the Baikal collaboration deployed and started operation of the first cluster of the Gigaton Volume Detector (Baikal-GVD). Named “Dubna”, the cluster compr...
Long-distance neutrinos
The neutrino is the most abundant matter-particle in the universe and the lightest, most weakly interacting of the fundamental fermions. The way in which a neutrino’s flavour changes (oscilla...
