Writing photons to disk - The triggerless DAQ-System of XENONnT — •Robin Glade-Beucke for the XENON collaboration — Physikalisches Institut, Universität Freiburg, 79104 Freiburg, Germany

The XENONnT experiment is an ultra low-background liquid xenon TPC for WIMP direct detection which is taking data at LNGS (Italy). Its triggerless data acquisition (DAQ) system allows for fast and storage-efficient recording with a very low threshold, accepting signals as small as from individual photons. Custom-developed FPGA firmware on the read-out digitizers and on auxiliary logic boards, e.g., a high energy veto to remove high-energy events during detector calibration, makes the data-taking in the triggerless paradigm possible. In this talk, I will present the system and its performance.
