The XENONnT Data Acquisition System — •Alexey Elykov for the XENON collaboration — University of Freiburg

The XENONnT experiment at the Laboratori Nazionali del Gran Sasso, is a liquid xenon-based multi-ton-scale dark matter detector which will be operational from early 2020. It will allow us to probe new parameter spaces of potential dark matter candidates and search for long sought-after decay processes. The scintillation and photoionisation signals that will occur in the detector due to particle interactions will be detected by 494 PMTs, amplified, digitised and recorded by a Data Acquisition (DAQ) system. This system is predominantly based on commercially available hardware and accompanied by custom-developed firmware and software. In combination with a novel data processing 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.
