Week 10 at the Pole

IceCube’s winterovers started off last week with continued detector troubleshooting from the previous week. Later in the week, they joined a South Pole webcast and gave an outreach presentation on their experience as winterovers. They also took advantage of being outdoors for some emergency response training to trek out to the IceCube Lab and get […]

Are extragalactic sources of ultra-high-energy cosmic rays efficient emitters of neutrinos?

The search for the sources of ultra-high-energy cosmic rays (UHECRs) is not a simple one. UHECRs, which are a mixture of protons and heavy nuclei, are the highest energy particles ever measured. They should produce “hotspots” of high-energy neutrinos if they interact with other particles near their point of origin. Six years ago, a first […]

Week 9 at the Pole

Last week was somewhat busy at the South Pole for IceCube’s winterovers. There were a couple of troubleshooting issues regarding the detector, and a trip or two out to the IceCube Lab (ICL). That’s Moreno below checking the status of some fans on computers in the ICL. On the recreational side of things, the winterovers […]

Improved reconstruction of low-energy events in IceCube

Every six minutes, a neutrino flies through the Antarctic ice sheet, and close to an IceCube sensor—also called a DOM—it interacts with a molecule of ice and creates a tiny amount of light that triggers data-taking for an event in the IceCube neutrino detector. If this is a high-energy event, a beautiful track or a […]

Week 8 at the Pole

It’s getting colder and colder at the South Pole. And when temperatures get too low, the winterovers can’t use snow vehicles to get around. But IceCube’s winterovers still had snow accumulation measurements to take last week, and the weather was not looking too favorable. Luckily, they did manage to find some open windows of opportunity […]

Week 7 at the Pole

Seasons come and seasons go. At the South Pole, you get only two seasons, and last week the South Pole station closed for…winter! (Isn’t it always winter there?) The last two planes carrying away summer workers left the Pole last week. The remaining winterovers said their final good-byes and then set themselves to the tasks […]

Week 6 at the Pole

Last week was quiet for the IceCube detector but not so quiet for the South Pole station—lots of activity going on there. The third and final South Pole traverse of the season, SPOT 3, arrived with its long load of fuel bladders, shown above and below, under a sun halo. SPOT3 was there just long […]
