Supporting Stations: McMurdo Station, South Pole Station
The pilot project for the Antarctic Ross Ice-Shelf Antenna Neutrino Array (ARIANNA) consists of seven autonomous stations, called the Hexagonal Radio Array (HRA). Located on the surface of the Ross Ice Shelf in Antarctica, the HRA is designed to detect short-duration radio pulses generated by neutrino interactions in the ice, which reflect from the ice-water surface at the bottom of the Ross Ice Shelf up to the stations on the surface. These measurements provide important insight on the locations of the most powerful particle accelerators in the universe and allow physicists to probe for novel physics beyond the standard model used in the field.
Field Season Overview
Four team members will travel by helicopter to the ARIANNA campsite at Moore's Bay, south of McMurdo Station. They will receive support contractor assistance to put in a three-week tent camp. While there, they will collect data from all stations, elevate solar panels to bit snow accumulation, and upgrade and test software. Upon returning to McMurdo Station, two participants will travel to South Pole Station. They will spend about 10 days moving the equipment installed last season to a new location near South Pole Station.
