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 […]

Successful design, production, and testing of LED calibration systems for Upgrade sensor modules
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 […]
Another successful field season for IceCube Upgrade at the South Pole
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 […]
Successful testing of over 10,000 photomultiplier tubes for IceCube Upgrade digital optical modules
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 […]
First field season for IceCube Upgrade ongoing at the South Pole
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 joins the IceCube Upgrade project
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 […]
Improved IceCube Upgrade optical module paves the way for IceCube-Gen2
The IceCube Neutrino Observatory, a cubic-kilometer-sized neutrino telescope, searches for high-energy neutrinos of astrophysical origin. Located at the geographic South Pole, IceCube consists of 5,160 digital optical modules (DOMs) across 86 vertical cables (strings) embedded deep within the Antarctic ice, as well as a surface array, IceTop, and a denser inner subdetector, DeepCore. When neutrinos […]
IceCube Upgrade Neutrino Monte Carlo Simulation
Introduction The IceCube Upgrade is an upcoming extension to the IceCube neutrino observatory which will densely instrument a 2 Mton region in the deepest ice, within the existing DeepCore sub-array. This new sub-array will comprise 7 new strings featuring a total of nearly 700 multi-PMT optical modules (known as mDOMs and DEggs) at a vertical […]
Putting neutrino masses in their place (soon!) with the IceCube Upgrade and JUNO
Neutrino mass ordering is one of the foremost problems in neutrino physics today. But two new neutrino oscillation experiments are on the horizon—the IceCube Upgrade and JUNO. So the IceCube Collaboration and the JUNO Collaboration studied the combined performance of their respective experiments, which employ very distinct and complementary routes in order to resolve the neutrino mass ordering. In a paper submitted recently to Physical Review D, they show that a combined analysis could eliminate the wrong mass ordering in as few as three years from the start of data taking. […]
