Calibration of the Radio Neutrino Observatory in Greenland

ORAL

Abstract

The Radio Neutrino Observatory in Greenland (RNO-G) aims to detect ultra-high energy (UHE) neutrinos in the PeV to EeV energy range through the detection of coherent Cherenkov emission produced via the Askaryan effect. The coherence increases in the radio regime, allowing for immense detector volumes due to the long attenuation length of radio waves in ice. Currently, seven stations are installed and operating at the NSF's Summit Station in Greenland. When completed, the detector will consist of 35 independent stations spaced roughly 1 km apart which each contain both high gain, shallow in-ice antennas and multiple strings of intermediate-to-deep, omnidirectional, low-gain in-ice antennas to detect the radio emissions. We will present the calibration of the geometry of the stations and implications for the instrument performance, with a special attention to the resolution on reconstructing the arrival direction of the radio signals.

*We are thankful to the staff at Summit Station for supporting our deployment work in every way possible. Also to our colleagues from the British Antarctic Service for embarking on the journey of building and operating the BigRAID drill for our project.We would like to acknowledge our home institutions and funding agencies for supporting the RNO-G work; in particular the Belgian Funds for Scientific Research (FRS-FNRS and FWO) and the FWO programme for International Research Infrastructure (IRI), the National Science Foundation (NSF Award IDs 2118315, 2112352, 211232, 2111410) and the IceCube EPSCoR Initiative (Award ID 2019597), the German research foundation (DFG, Grant NE 2031/2-1), the Helmholtz Association (Initiative and Networking Fund, W2/W3 Program), the University of Chicago Research Computing Center, and the European Research Council under the European Unions Horizon 2020 research and innovation programme (grant agreement No 805486).
