The XENONnT Data Acquisition System — •Alexey Elykov for the XENON collaboration — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

The XENONnT experiment, currently under construction in the Laboratori Nazionali del Gran Sasso, is a liquid xenon-based multi-ton-scale dark matter detector. It will allow us to probe new parameter spaces of potential dark matter candidates and search for long sought-after processes, like neutrinoless double beta decay. The scintillation and photoionisation signals that will occur in the detector due to particle interactions will be amplified, digitised and recorded by a Data Acquisition (DAQ) system. This system is predominantly based on commercially available electronics, accompanied by custom-developed firmware and software. In combination with a novel data processing and data reduction framework, it can operate with high efficiency both during the acquisition of low rate dark matter search data and throughout high rate calibration efforts. In this talk, an overview of the XENONnT DAQ system will be presented, as well as its status and potential future developments.
