The Radio Neutrino Observatory in Greenland (RNO-G) - System Design and Instrumentation

Abstract

The Radio Neutrino Observatory in Greenland (RNO-G) is designed to measure cosmic neutrinos in the EeV range through an array of radio antennas detecting nanosecond-long radio flashes. In this contribution, the RNO-G electronic system is outlined, illustrating how signals are measured from the antennas to the recorded pulses. We present new instrumentation developments, focusing on electric melters to install LPDA antennas into the Greenlandic ice sheet. The new system will simplify deployment and reduce positioning uncertainty to $\pm$2cm (x/y) and $\pm$1°(rotational). We report on field tests from the RNO-G site at Summit Station.
