The IceCube detector has been explained widely—in many different languages and in hundreds of locations around the world, and targeting diverse audiences online as well as in auditoriums, museums, and classrooms. But this is the first time that the IceCube Collaboration is making public every detail of the only cubic-kilometer neutrino detector to date, from a flasher board in the digital optical modules—aka DOMs—to the calibration processes that allow researchers to measure the properties of neutrinos, or to the IceCube Live website that IceCubers use to monitor what is going on in the detector. The publication, over 70 pages long, has just been submitted to the Journal of Instrumentation.
A clear sky last week showed off some faint sun dogs around a bright sun. Clear skies also made for fine flying conditions—the last flights to leave the Pole took off last week. The station is officially closed for the season.
Shadows are getting longer as the first large group of summer workers heads out from the Pole. Soon enough the flights will end, leaving the winter crew alone for the dark months to come.
Winter is just around the corner, but the South Pole greenhouse doesn’t know about it. Fresh vegetables are growing in there. IceCube winterover Martin had some greenhouse training last week, and harvested a striking (but not very ripe looking) tomato.
Doesn’t it sometimes seem that folks at the South Pole are always smiling? Well, for many, getting to spend time at the Pole—extremely cold temperatures notwithstanding—is the dream of a lifetime. Still, this group shot shows summer crew about to leave for warmer climes. Maybe that’s why they’re smiling.
The American Physical Society meeting on astronomy, astrophysics, cosmology and particle physics, the so-called April meeting, closes today in Washington DC. The IceCube Collaboration has presented brand new results on neutrino oscillations that are comparable in precision to long-baseline neutrino experiments. From WIPAC, many PhD students and more senior staff presented results about IceCube, including the masterclass, along with results on CTA and Fermi.
