Description
The Radio Neutrino Observatory Greenland (RNO-G) is searching for Askaryan radio signals from ultra-high-energy neutrinos ($E \ge 100\,$PeV) interacting in ice. RNO-G is currently under construction near the apex of the Greenland ice sheet with 8 stations already operational and collecting science data. The constructed observatory will consist of 35 autonomously operating stations deployed over an area of about 50$\,$km$^2$. Its projected sensitivity will allow to test several models of astrophysical and cosmogenic neutrinos with the potential to detect neutrinos above 100$\,$PeV.
Each RNO-G station features 24 radio antennas installed in 3 100$\,$m-deep-boreholes with a diameter of 30$\,$cm and shallow trenches beneath the surface. The stations are powered by solar and wind energy and are each equipped with low-power electronics for data readout and wireless communication to a central server at the nearby NFS-operated Summit Station. RNO-G is the first experiment probing the large-scale in-ice radio detection with tens of stations and hundreds of channels over a large area. It is designed to withstand the harsh conditions of an Arctic environment, with scalability in mind. As such, its construction and operation provides invaluable insights for the development and construction of the planned 500$\,$km$^2$ radio detector of the IceCube-Gen2 facility.
In this contribution, I will give an overview of recent deployment activities, the operation of the 8 deployed stations and discuss the hardware performance over the past 4 years.
