The XENONnT Data Acquisition System — •Robin Glade-Beucke for the XENON collaboration — Albert-Ludwigs Universität, Freiburg, Germany

The XENONnT experiment is an ultra-low background liquid xenon TPC for direct dark matter detection. Its trigger-less Data Acquisition System aims at achieving maximal total uptime and the lowest possible energy threshold. Live processing of the data allows timely insight in current data taking, even in high-rate scenarios such as during calibration. Later reprocessing with improved processing parameters is possible. The high data rates during calibration can be mitigated on-line with FPGA-based veto decision-making.
