Scientists suggest that the icecube should be eight times larger

The Icecube Neutrino LaboratoryPowered by University of Wisconsin-Madison (UW-M), located in Amundsen-Scott South Pole Station In Antarctica, one of the most ambitious neutrino observatories in the world. This is behind the lab Icecube collaboration, an international group of 300 physicists from 59 institutions in 14 countries. Relying on a cubic kilometer of ice to shield it from external interference, the observatory is dedicated to searching for neutrinos. These nearly massless subatomic particles are abundant in the universe and are constantly passing through normal matter.

By studying these particles, scientists hope to gain insight into some of the most violent sources of astrophysics, such as supernovae, gamma-ray bursts, black holes and merging neutron stars. Also known as research Particle Physics Project Preferences Panel (P5). In a recent draft report, “Pathways to innovation and discovery in particle physics,” the P5 group recommended a Expansion of IceCube is planned. This recommendation is one of many that will define the future of astrophysics and particle physics research.

Along with CERN’s other projects, the report also recommends support for a separate neutrino experiment based in Illinois called the Deep Underground Neutrino Experiment. Large Hadron ColliderThe Vera C. Rubin ObservatoryThe Cherenkov telescope array, and the development of next-generation ground-based telescopes to monitor the cosmic microwave background (CMB). P5 advisors include two UW-Madison faculty members, Dulika Bose And Kyle Cranmerand UW-Madison physicists also play leading roles in the projects listed above.

Bose is an experimental particle physicist who works on Compact muon solenoid Experiment at the LHC. His research focuses on the search for exotic particles, dark matter, and Standard Model measurements. Cranmer’s research focuses on the search for exotic particles and physics beyond the Standard Model. Atlas Experiment at the LHC. Together with their P5 colleagues, the two have spent much of the past year assessing the future of particle physics and recommending projects to help advance the field.

One of the main concerns of the P5 group is how the limited funding allocated by the federal government to particle physics research can be increased over the next decade. This is one of the main reasons for the recommended icecube expansion, as it is colloquially named ICECube-Gen2. As they mention Their statementUpgrades to the current observatory are a relatively cost-effective way to improve the scientific community’s ability to detect and analyze neutrinos:

„IceCube-Gen2 also has a strong scientific case for multi-messenger astrophysics in conjunction with gravitational wave observatories… The South Pole is a unique platform that will enable the world-leading science of CMB-S4 and IceCube-Gen2 to be maintained as a primary science platform that will allow US leadership in these fields to continue.”

„By using new technology and using smarter ice that can be modeled with ever-higher accuracy, IceCube-Gen2 can increase the detection rate by eight times at a cost comparable to the IceCube,” he said. Albrecht KarleA UW-Madison professor of physics, he leads the IceCube upgrade at UW-M. Press release.

In addition to supporting the IceCube expansion and other key experiments, the committee recommended improved funding balance between all-scale projects, a more intensive research and development program leading to the next-generation particle accelerator, and expansion of the nation’s advanced technology workforce. . Bose noted that he was particularly excited by the prospect of a new particle accelerator, which has the potential to be in the U.S. „I am excited by the bold long-term vision presented in the P5 report,” he said. „Such a collision would be an unparalleled global facility, providing new insights into the mysteries of our quantum universe.”

The recommendations of the P5 group are now under review Advisory Committee on High Energy Physics (HEPAP), part of the US Department of Energy (DoE), will meet on December 8 to discuss the recommendations.
