Improved Trigger for the Radio Neutrino Observatory in Greenland (RNO-G)

The Radio Neutrino Observatory in Greenland (RNO-G) is a currently under construction detector aimed at detecting ultra-high energy (>100 PeV) neutrinos using radio frequency antennas. At 8 of 35 currently deployed stations and with 5 years of data, we have a better understanding of the detector and the local ice environment. In anticipation of expanding the detector we present a new beamformed triggering method that runs on the current hardware. The new trigger has been running on every station for the 2025 season, and its performance has been validated by in-situ testing and lab testing. The trigger is expected to improve the sensitivities of each station by up to a factor of 2. We further show an updated effective volume using this trigger with more detailed simulations including more refined detector, ice, event generation, and neutrino RF emission models.
