IceCube extension

Coordinating university or institute

Uppsala University,

Project description

IceCube is the largest neutrino detector ever built. It is located at the South Pole where 1 km3 of the deep glacier ice has been instrumented with over 5000 optical sensors. The sensors are attached to cables that have been deployed into vertical holes drilled using jets of hot water. The digital optical modules are read out with a timing precision of a few ns.
For a future expansion of IceCube we are now looking for companies that can develop hybrid, fiber-optical cables to exigent specifications, help develop radio technology for neutrino detection or provide wind turbines and batteries for polar conditions. We are also interested in small cameras for deployment into the ice together with optical modules.
