Last week’s excitement for the IceCube Upgrade project centered around moving the drill tower and operations structures into place. The location is over hole 87, which will be the first Upgrade hole (the IceCube detector has 86 holes). The installation team is also making progress on setting up the area for acceptance testing of the […]
As the season progresses, the IceCube Upgrade team continues to grow. Eight more arrivals last week brought the South Pole IceCube population up to 29. As newcomers acclimated, the “old-timers” kept up with the snow grooming around drill camp—things are looking good there. They continue to shovel out other structures and have been “harvesting” hoses, […]
After the first group of IceCubers spent a couple of days acclimating and reviewing the work needed to get the drill camp up and running, the crew went straight to work. The first order of business? Shoveling. And lots of it. They managed to shovel out most of the buildings in the drill camp. The […]
The first week of the final field season for the IceCube Upgrade started out with delays. Figures. Of course, even though that’s not what you hope for, uncooperative weather at the South Pole is a fact of life, something to deal with in stride. The first group of IceCubers for the Upgrade season had to […]
As cosmic rays collide with particles in the Earth’s atmosphere, air showers containing atmospheric muons and neutrinos are produced. The atmospheric neutrinos are then detected by DeepCore, a denser and smaller array of sensors in the center of the IceCube Neutrino Observatory at the South Pole. Compared to the main IceCube detector, DeepCore is sensitive […]
Neutrinos are weakly interacting particles that are able to travel unhindered through the cosmos. When a neutrino interacts with a molecule in the ice, blue light is emitted from the resulting secondary charged particles through a process called Cherenkov radiation. The IceCube Neutrino Observatory at the South Pole consists of an array of 5,160 optical […]
Since November of last year, a team of IceCube engineers and scientists have been hard at work during the second of three consecutive field seasons for the IceCube Upgrade. Over the course of the season, 37 team members, including 27 drill engineers and 10 installation and operations experts, were deployed to the U.S. National Science […]
At the South Pole, the cubic-kilometer-sized IceCube Neutrino Observatory searches for high-energy neutrinos of astrophysical origin. When a neutrino crashes into the ice, blue light is emitted and detected by some of IceCube’s 5,160 digital optical modules (DOMs) across 86 vertical cables (strings) embedded deep within the Antarctic ice. The IceCube Upgrade, an enhancement to […]
Over the past two months, a team of IceCube drill engineers have completed an impressive amount of work during the first of three consecutive field seasons for the IceCube Upgrade. The project is funded by the National Science Foundation and international collaborators. The goal of the project is to drill seven holes in 2025/2026 and […]
Thai engineer Chana Sinsabvarodom was recently selected to work on the IceCube Upgrade project, which will install seven more densely instrumented strings of light sensors near the center of the IceCube array at the South Pole. The IceCube Upgrade will significantly enhance IceCube’s sensitivity to lower-energy neutrinos, improve the fidelity of all past and future […]
