Abstract
The Askaryan Radio Array (ARA) experiment aims to detect ultra-high-energy cosmic neutrinos
(>10 PeV) using radio detection techniques. To enhance ARA’s capabilities, a new RFSoC-based
DAQ, ARA-Next, is in the early stages of development. This advanced system will facilitate the
creation of sophisticated triggers, including a novel multi-trigger approach, similar to those used
in collider experiments. Our approach involves crafting and implementing innovative triggers for
ARA’s new DAQ, such as identifying double pulses from potential in-ice neutrino interactions,
utilizing templates for atmospheric cosmic ray signals, optimizing triggers for astrophysical neu-
trino sources, correlating special events between ARA and IceCube, and discerning anthropogenic
events using directional information. These trigger designs aim to lower thresholds and enhance
ARA’s detector sensitivity. Overall, this upgrade will not only enhance ARA’s capabilities but
also contribute to the technological advancements necessary for future experiments of this nature.
